Renting vs. Buying Temporary Containment Walls

The world of construction and design is always advancing as innovative, cost effective, and sustainable solutions are introduced into the marketplace. Temporary modular containment walls are the perfect example of this. Modular containment walls—like our SHIELD WALL™ system—are a versatile and adaptable alternative to traditional drywall and poly sheeting containment methods. 

Temporary modular containment walls offer a variety of benefits to commercial construction and renovation projects, from an aesthetically pleasing appearance to a more efficient set-up. Modular containment systems can be installed significantly faster than traditional methods, saving time and reducing labor costs. These reusable walls are constructed with eco-friendly materials, meaning less waste and faster cleanup at the end of a project. 

The flexibility, speed, and cost effectiveness of temporary modular wall systems have redefined the way contactors contain dust and other airborne pathogens during construction. From hospital construction to office space renovations and many other projects, and whether buying or renting,  temporary modular wall systems provide a practical and sustainable alternative to older containment methods. While purchasing the walls is an excellent multi-use solution, renting can also be an attractive option.

Renting Modular Containment Walls

Though the upfront cost of modular containment systems may seem comparable to traditional methods, time and labor savings in addition to reusability make them the most cost-effective solution. In fact, our SHIELD WALL™ containment walls can pay for themselves in as few as two or three uses, depending on the scope of the project. Purchasing modular containment walls outright is an easy decision for some while others, especially those with short-term projects, or those who do not have the storage space between jobs, may benefit from using a rental service that provides the containment walls alongside a quick installation and teardown service.

Renting the walls can reduce the initial investment, which is helpful when you're looking to control costs while still reaping the benefits of modular containment solutions. For some companies, the expense of renting may fall under a different budgetary spend, making it easier for approvals. Renting also allows contractors to try the modular walls before purchasing to assess how they will work in different spaces and help make decisions about whether they’re a good long-term investment.
For some, purchasing modular containment walls outright is the best option, but those with short-term projects may benefit more from leasing or renting the walls. Companies can work with a knowledgeable team of experts to help determine what will work best for their project. These experts may ask key questions, such as:

  1. How many projects do you have that require containment?
  2. Do you have space to store modular walls between projects?
  3. What is the length of time between the start and finish of a project? 
  4. Do you have the staffing to install and maintain the walls?

While purchasing the walls is an excellent long-term solution, renting can also be an attractive option. And, with a knowledgeable team of IAQ experts on staff, Abatement Technologies’ consultants can help guide you through the selection process and help determine if renting is the best financial route for your needs. 

Blog #5 – DUCT-PRO®: Cleaning the Return

Abatement Technologies® is the industry leader in quality duct cleaning solutions. Our high-performance DUCT-PRO® packages utilize HEPA-AIRE® equipment to clean HVAC duct systems faster and more efficiently than other methods. Abatement Technologies’ equipment uses our exclusive source removal duct cleaning process, meaning our equipment captures dirt and debris to provide complete air duct cleaning and decontamination. Our source removal duct cleaning process is designed to work with the tools and procedures professional duct cleaners need to follow the NADCA recommended steps for cleaning air duct systems effectively.

We have created a blog series based on our official DUCT-PRO® training videos to guide users through the proper DUCT-PRO® processes and procedures. In our last post, we covered the proper steps for agitation to remove debris and dirt from the ductwork. Here we’ll cover the procedure for cleaning the return.

Attaching the Vacuum

Check the power vacuum filters after the supply system has been cleaned and clean or replace them if necessary. It’s also a good idea to check the moisture filter and drain it if needed. After examining these areas inspect the ductwork and furnace layout to determine the best locations for hookups. Taking the time to complete this step now will save time later in the process.

To attach the vacuum, the duct cleaning professional will cut a hole in the return plenum on the upstream side of the filter and then attach the quick connect collar. The filter should be removed if it is upstream from the vacuum hose. Then the zone bag can be put in the main duct above the coil, preventing air from being pulled through the previously cleaned supply side of the system.

Cleaning the Return 

The return duct system should be cleaned using the same procedures that were used on the supply side. Duct cleaning pros should keep in mind that return systems are typically much dirtier than the supply side and require more brushing and air sweeping. It’s important to properly clean the equipment after use. Place the air hose from the power vacuum in the blower compartment and air wash the blower compartment with the DUCT-PRO® air booster gun when all the duct work has been completely cleaned.

Sanitizing can begin once the return is clean, it’s important to read the label and follow the manufacturer’s directions accurately before using any sanitizer. Be certain the product has an EPA registration for its intended purpose, follow the manufacturer’s recommendations regarding personal protective equipment (PPE), and ensure all grills and registers are covered before sanitizing. Adding a drop cloth around the work area to prevent damage to the flooring surfaces is also a good idea.

Air Duct Sanitizing 

These instructions are for non-porous duct systems. Due to the porosity of the material, there are no sanitizers with EPA registration for use in porous ductwork such as duct board or lined duct.

The sanitization process is generally conducted using a ULV fogger which produces a variable flow from light fog to a heavy mist, adjusted at the nozzle. The correct output is a mist that will quickly wet the entire surface without creating puddles.

A good practice is to fog the branch runs with slight negative pressure in the duct system. This not only helps pull the fog through the ductwork but also helps to prevent the sanitizer from entering the room, and can be accomplished by attaching the vacuum to the original hookup point. If the duct system is small, adjust the airflow of the DUCT-PRO® HEPA-AIRE® vacuum for better coverage before fogging. Allow all surfaces to dry before restarting the air handler.

Blog Series #4 – DUCT-PRO®: Agitation

Abatement Technologies® is the industry leader in quality duct cleaning solutions. Our DUCT-PRO® source removal cleaning packages utilize our HEPA-AIRE® equipment to clean HVAC duct systems faster and more efficiently than other methods. Abatement Technologies’ equipment uses our exclusive source removal duct cleaning process to capture dirt and debris and provide complete air duct cleaning and decontamination.

Our source removal duct cleaning process is designed to work with the tools and procedures professional duct cleaners need to follow the NADCA recommended steps for cleaning air duct systems effectively. We have created a blog series based on our official DUCT-PRO® training videos to guide users through duct cleaning processes and ensure the equipment is used properly and efficiently.

We’ve looked at the methods for duct cleaning and air sweeping in our previous posts. 

In this installment, we’ll cover agitation—a process for dislodging the extreme buildup of debris prior to air sweeping.

Methods for Agitation 

Manual brushes or whips with add-on rods are some of the most used tools and methods for agitation. The procedure is similar to chimney sweeping, with the brushes swept horizontally instead of vertically. The DUCT-PRO® power rod system is used with compressed air and has lengths of connected rods with three different flexibilities. Each rod has a special fitting that connects to various whip heads.

The DUCT-PRO® power brush system is a powerful method of agitation in large ducts and for commercial applications. This system is driven by its own power source and enables the use of both compressed air and brushes for optimal performance. The remote-control setting allows cleaners to operate the compressed air, rotation, and speed functions. The brushes can be turned both clockwise and counterclockwise to clean both sides and bottom corners. 

There are many advantages to the system, including brushes of different sizes and bristle stiffness designed for various duct types. The softer brushes should be used for inline duct and duct board and stiffer bristles for metal. It is important to do a thorough examination prior to cleaning to determine the condition of the ductwork. 

The DUCT-PRO® power brush system offers contractors the unique capability to use both forward and reverse compressed air, allowing cleaners to brush and air sweep at the same time.

Power brushing eliminates the need for an extra access hole and speeds up the cleaning process while producing excellent results. 

We’ll explore the proper steps for cleaning the return side of the ductwork in our next blog.

Blog Series #3 – DUCT-PRO®: The “Push” Method

Abatement Technologies® is the industry leader in quality duct cleaning equipment. Our DUCT-PRO® source removal duct cleaning process provides contractors with the tools needed to follow the NADCA recommended steps for cleaning air duct systems effectively. With DUCT-PRO, contractors can benefit from a faster and more efficient cleaning process and customizable duct cleaning packages, and Abatement Technologies® can help contractors select a package that is suited to their needs.

It’s important to understand the role each piece of equipment plays in the duct cleaning process to ensure their efficiency and proper use. In previous blogs, we’ve explained the necessary equipment and prep work and the process for cleaning the HVAC supply. In this blog, we’ll explain the methods for duct cleaning, beginning with the “push” method. 

Conducting the “Push” Method

Once the grills have been covered in the preparation stages, duct cleaning professionals can begin the “push” step of the process using specialized air tools and nozzles operated by the DUCT-PRO® AIRE-SWEEP® portable air compressor. The duct cleaning professional should give the furthest grill an initial air wash using a light blast from an air booster gun, then clean the entire grill completely. In this step, many duct cleaners will also wash and sanitize the grills.

The branch duct will then be cleaned using a forward air sweep. This step uses a nozzle that has holes pointing in a forward direction, which pushes the debris forward toward the main duct and to the power vacuum. Forward air sweeping should be done until the branch is clean. Another common method of branch cleaning is the reverse air sweep method, which is usually done if the ductwork is in the basement and affords easy access. 

Once each branch is clean, the grills should be replaced and the main duct can be cleaned. This process typically involves the use of the reverse air sweep.  However, in an attic or crawl space, the forward air sweep is used. 

Cleaners will often need to air sweep each section of the ductwork several times before they’re considered clean. The cleaners will know the section is clean when they no longer hear or see debris being pulled through the clear power vacuum hose.

In the event of extreme debris, agitation may be required to dislodge the buildup prior to air sweeping. We’ll explain the proper tools and systems for agitation in our next blog.

Blog Series #2 – DUCT-PRO®: Cleaning the Supply

Abatement Technologies® is leading the duct cleaning industry with our quality equipment and innovative solutions. Our DUCT-PRO® source removal duct cleaning packages provide the tools professional duct cleaners need to follow the NADCA recommended steps for cleaning air duct systems effectively.

Our DUCT-PRO® cleaning process has been designed to create new business opportunities for contractors. It is faster and more efficient than other solutions on the market, and our customizable duct cleaning packages can accommodate each contractor’s unique requirements. We have developed a process to ensure duct cleaners select the right package for their needs and can customize everything from the vacuum to the AIRE-SWEEP® portable air compressor, agitation devices, and accessories.

It’s important to understand the role each piece of equipment plays in the process to ensure their efficiency and proper use. Our team of Aire Guardians at Abatement Technologies have® created a video series to provide users with the information needed to clean HVAC duct systems quickly and efficiently, leading to a profitable indoor air quality business. 

To accompany the training videos, we’ve created a blog series to help break down the steps and process for using DUCT-PRO®. In our last post, we covered the proper protective equipment and prep work needed to efficiently clean ducts. Here we'll discuss the proper steps for cleaning the supply side of the ductwork. 

Steps for cleaning the supply

The duct cleaning professional will prepare to clean the supply side by cutting a 12-inch access hole.  If cutting a 12-inch hole is not possible, the largest possible size should be cut, keeping in mind that the larger the hole, the better the airflow. If the duct is constructed with duct board instead of sheet metal, it's important to hold the hole cutter blade at a 45-degree angle (similar to cutting the top off of a pumpkin) to achieve a good fit when replacing the piece at the end of the project. 

This access hole is typically cut into the plenum, as high above the coil as possible. Sometimes, the hole is cut into the main duct close to the plenum. It’s important to cut the hole high enough that the cutting doesn’t damage the coil. It’s a good idea to protect the coil by covering it with a tarp or piece of plastic to prevent debris from falling into it during the cleaning process. 

Once the access holes are made, a quick connect adaptor is screwed over the holes using zip screws to hold it in place. The contractor will then use flexible ducting to attach the quick connect collar which will be held in place using the locking collar. Duct tape can be used in this step to attach the quick connection to the duct board. 

The contractor should check all damper settings in the branches and main ducts before beginning the cleaning process to ensure they are all open. With the DUCT-PRO® power vacuum connected to the supply, the duct system can be turned on to create a strong airflow through its supply.

In our next post, we’ll share how to properly conduct the push method in duct cleaning.

Blog Series #1 – DUCT-PRO®: Preparing for the job

Abatement Technologies® is the industry leader in quality duct cleaning solutions. Our high-performance DUCT-PRO® packages utilize HEPA-AIRE® equipment to clean HVAC duct systems faster and more efficiently than other methods. Abatement Technologies’ equipment uses our exclusive source removal duct cleaning process, meaning our equipment captures dirt and debris to provide complete air duct cleaning and decontamination.

Our source removal duct cleaning process is designed to work with the tools professional duct cleaners need to follow the NADCA recommended steps for cleaning air duct systems effectively. Abatement Technologies® DUCT-PRO® equipment is designed for contractors looking to expand their existing business. DUCT-PRO® enables professionals to offer duct cleaning as an add-on service, which can lead to more business opportunities and higher revenue. 

It’s important to understand the role each piece of equipment plays in the process before starting a duct cleaning business. Our team of Aire Guardians at Abatement Technologies® has created a video series to provide users with the key information needed to safely start using DUCT-PRO®. We’ve created a blog series to accompany our training videos and help break down the process for using DUCT-PRO®. In this blog, we’ll discuss the proper accessories and equipment needed for the job as well as the necessary prep work for their optimal performance. 

DUCT-PRO® Accessories & Equipment 

We recommend beginning any duct-cleaning project with personal protective equipment (PPE) including safety glasses and respirators. Additional recommended PPE includes cut-resistant gloves and sleeves to reduce injuries when reaching through ductwork with sheet metal cutouts. 

Once the proper PPE has been identified, it's time to identify which duct cleaning method is right for the job. Our  DUCT-PRO® system uses the state-of-the-art source removal duct cleaning push/pull method. The “push” mechanism is achieved with high-velocity compressed air tools while the “pull” mechanism is accomplished by creating powerful airflow through the air conveyance system with the use of the HEPA-AIRE® portable vacuum included in the DUCT-PRO® package from Abatement Technologies®.

Duct Cleaning Prep Work

Next ensure the furnace, AC, and duct systems are turned off and will remain off for the duration of the project. It’s also good practice to turn off the air handling unit at the thermostat as well as the circuit breaker to prevent accidental startup. It’s important to be aware of, and adhere to, all local regulations regarding gas pilot lights and other utilities before beginning any project.

The duct cleaning professional should conduct a thorough inspection of the project site to identify any potential safety concerns and determine the layout of the ductwork once the systems have been turned off. During this process, the duct cleaning professional will examine the condition of the ductwork and determine the type of air handler used so they can develop a plan for hookup points and air sweeping procedures. It’s important to understand how to clean the supply and return duct networks to avoid pulling debris through the heat exchanger and coil. To separate the supply and return, simply pull out the furnace filter and insert an inflatable zone bag into the air handle to isolate the supply and block airflow. 

Grill masking tape should be used to seal off the registers and increase airflow through the branch being cleaned. It’s important to keep the furthest two or three vents uncovered during this step to allow air into the ductwork to create airflow. The airflow will be inadequate for transferring debris to the power vacuum if all vents are covered.

Our DUCT-PRO® HEPA-AIRE® portable vacuums are designed to pull large volumes of debris through the duct system and filter all of the contaminants before exhausting clean air from the vacuum. For optimal performance, the vacuums should be placed as close to the furnace as possible. 

When the filters become dirty, audio and visual alarm cues will signal that airflow has been reduced and it’s time to change them. Most operators prefer to change the HEPA filter every one to two years of use.

IAQ Is Creating Big Opportunities for Service Contractors

Indoor air quality is creating big opportunities for service contractors

Residential and commercial air duct cleaning is one of the most lucrative business opportunities in the booming indoor air quality field, with excellent annual growth rates. Industry analysts expect this growth rate to continue through increased customer concern about IAQ in their homes and businesses.

Whether you’re already offering contracted services or you’re interested in getting into the indoor air quality market for the first time - we have a list of considerations to help you in the decision making process.

Cashing in on indoor air quality

Air duct cleaning services allow contractors to increase profits in an ever-growing market. A number of factors make air duct cleaning an attractive business opportunity, such as the following:

- Great return on investment

- Diverse business opportunities

- DUCT-PRO® equipment leasing programs

- Be in control of your earnings and profit

- Provide significant add-on revenues with existing customers

- Generate new customers for other products and services

As the industry leader since 1990, Abatement Technologies® has helped thousands of companies develop and grow successful air duct cleaning businesses. High-performance DUCT-PRO®  and HEPA-AIRE® equipment has helped professionals clean HVAC systems in millions of homes and commercial buildings. 

What is source removal and capture duct cleaning?

Studies have shown that even a small amount of dirt buildup on HVAC system components can significantly reduce HVAC efficiency and increase energy consumption. Complete removal of dirt, debris, and other contaminants from the air duct system is the most effective and acceptable cleaning and decontamination method for ductwork in both homes and commercial buildings.

Abatement Technologies' duct cleaning method goes a step further by combining effective source removal with source capture. Here's how we do it:

- A specially designed compressor equipped with special agitation tools is used to loosen or dislodge dirt, debris and other contaminants from inner ductwork surfaces.

- A HEPA-AIRE® portable vacuum system is taken right into the home or building and plugged into a standard 115 V wall outlet. It combines the power needed to place the ductwork under negative pressure and pull out the contaminants, with a stage 3 filtration system, that has the efficiency and capacity needed to capture them.

Because the HEPA-filtered air exhausted back into the indoor environment from the vacuum is cleaner than many hospital operating rooms, there is no need to pull huge amounts of heated or cooled air out the building and exhaust it outside, as must be done with gasoline or diesel-powered equipment.

The Best Ways to Enhance Whole-Home Air Purification

Learn about the best ways to enhance whole-home air purification

Clean purified air is desired more than ever, especially in our homes. Harmful particles and pathogens can pose a risk on our short and long term health. There is advanced purification technology that exists and is created with the intention of trying to improve whole-home air quality. Allergists and other medical professionals widely promote allergen avoidance as a way to improve health of sensitive individuals with respiratory diseases.

 

The premise is simple, reduce exposure to pollutants. Central Air Purification (CAP®) units from Abatement Technologies incorporate one or more effective and targeted air purification technologies for this purpose.

 

Mechanical particle filtration

 

Filters are assigned a minimum efficiency reporting value (MERV) rating between 1-16, the higher the rating the better the filter is at removing small particulates. A standard low-efficiency throwaway furnace filter rated at MERV1 or MERV2 is only effective for large particles.

 

CAP®100, CAP®600 and CAP®1200 series HEPA Air Purification Systems are equipped with MERV 4 first stage pre filters designed primarily to capture large, visible dirt and dust particles that are too large and heavy to be respirable, but can become a housekeeping issue when they accumulate on surfaces. The second stage pleated particle filters in these CAP® models capture smaller, visible particles that can easily pass through most throwaway furnace filters. The high-capacity 5” deep CAP®100 series second stage filter, MERV 13 is especially effective. 

 

Activated carbon filtration

 

The VAPOR-LOCK® activated carbon filters utilized in CAP®600 Series and CAP®1200 Series models capture airborne gasses, volatile organic compounds off-gassed from carpets, composite wood furniture and other materials in the home, and odors caused by pets, cooking or smoking. VAPOR-LOCK® filters utilize a process known as adsorption, in which the gas-phase molecules of the contaminants are attracted to and chemically bond to the surface of the carbon. 

Combining UV Germicidal Irradiation and Photolysis Technologies

Over time our homes endure different issues like persistent molds and fungal odor problems usually found in areas with high moisture or humidity levels like the damp, dark and dirty recesses of an HVAC system where organisms can thrive and multiply.

CAP® systems are equipped with our advanced, dual frequency UV plus lamp. Frequency one creates germicidal UV energy to irradiate and break down molds and fungi. The second frequency creates a controlled amount of trivalent oxygen for enhanced odor-neutralizing capability

CAP®100, CAP®500, CAP®600 and CAP®1200 Series Whole-Home Central Air Purifiers are equipped with germicidal UV lamp technology. Microorganisms are irradiated to high levels of UVGI energy each time they pass by the lamp as the air cycles through the central HVAC system of your home. All CAP® germicidal UV lamps are ozone-free. 

HEPA Filtration

The beauty of a HEPA filter is that its efficiency starts at 99.97% and actually improves as the filter loads. Because of the exceptional small-particle capture performance of CAP®600 Series and CAP®1200 Series models, these units are the most widely recommended for homes with family members who are asthmatic or have the highest sensitivity to respiratory allergens.

The Secrets Of Negative Pressure Containment

The Secrets of Negative Pressure Containment

The average hospital lasts more than 40 years, and often as many as 100 years. If you've ever considered buying an old house, or seen others do it on TV, you know just how much renovation and maintenance they require. Now multiply the square footage by more than 10, and you can imagine how much renovation is consistently needed in hospitals not only to keep them going but to continually improve services and meet changing building requirements.

While renovation and maintenance projects may pose little more than an inconvenience to homeowners, they require special attention in healthcare facilities because of the danger that airborne particles, spores, and pathogens released into the air by construction pose to patients. In order to carry out essential construction and maintenance work without harming patients, construction zones must be sealed off from patients, and air must be filtered and diverted away from vulnerable patients. 

To do this, facilities must perform Negative Pressure Containment. 

What is Negative Pressure Containment?

By its very definition, a negative pressure room has more air exiting it then entering. There is less air inside the room compared to the other rooms, hence why it is negative. What this does is ensures that any airflow outside of the HEPA exhaust is flowing into the room to fill that vacuum. Because airflow can only flow in one direction through the cracks or designated makeup air locations, the contaminants cannot escape the room.  Always check regulations when exhausting inside a healthcare facility as regulations can vary.

How to create Negative Pressure Containment

There are four key steps to creating negative pressure containment:

1. Construct a physical barrier around the area. 

Product Tip: You can do this with Abatement Technologies' AIRE GUARDIAN® SHIELD

2. Seal off any HVAC Returns

Tip: This ensures that dirty air does not escape into the rest of the building. 

3. Filter air in the sealed room with a portable air scrubber (PAS)

Product Tip: Use a HEPA-AIRE® or PREDATOR® series Portable Air Scrubber (PAS) from Abatement Technologies.

4. Use a PAS (portable air scrubber) to exhaust the filtered air out the construction zone through duct work

Product Tip: Find compatible duct here

Get it right everytime

Before attempting to create negative pressure, use our air change calculator to determine your airflow needs. Once you’ve followed the four steps above, use a portable differential pressure monitor for the most accurate reading of your negative pressurization.
