In this configuration, the unit pulls in contaminated air, filters out contaminants and propels the filtered air outside the environment to negatively pressurize the room. Click on the arrow to view the animation.

Negative Pressure Mode with HEPA-Filtered Air Exhausted Into a Ceiling Plenum

In this configuration, filtered air from a portable unit in the room is ducted out the top exhaust port and into the plenum area above the drop ceiling. If a ceiling-mounted fixed model is used, the unit can simply exhaust out one or both of the exhaust grills directly into the space above the drop ceiling. Click on the arrow to view the animation.

Note: This option is for conversion of existing patient rooms into patient isolation rooms but should not be used for new facility renovation or construction.

Continuous Air Cleaning and Recirculation

The unit is located within the isolation room with no inlet or exhaust ducting, so there is no affect on room pressurization. This setup accelerates the removal rate of airborne contaminants and provides supplemental ACH equivalents. Click on the arrow to view the animation.

50% Negative Pressure Exhaust and 50% Negative Pressure

Air is ducted to the outdoors from one outlet for negative pressure and recirculated into the room from the other. Running a HEPA-CARE unit in this configuration at high speed provides the ability to clean the air in some rooms up to 30 times per hour, without having to exhaust that much conditioned air from the building.

HEPA-CARE Air Purification Systems can also be located within the room (as shown) or in an adjacent area to provide HEPA-filtered supply air and positive room-pressurization for Protective Environments and other sensitive areas. Click on the arrow to view the animation.
