For temporary, relocatable use whenever and wherever you need clean air, we offer Criti-Clean Ultra in convenient portable units. They are mounted on swivel casters for easy movement, plug into standard electrical wall outlets and can be placed virtually anywhere to provide effective HEPA filtration. Our portable FFUs are available in both air recirculating and reverse-flow models:
Recirculating Units
The recirculating unit draws air in through the back and expels HEPA filtered air out through its face, continually circulating and filtering the air in any room. CFM can easily be set and monitored from the front of the unit to meet air change requirements.
Reverse Flow Units
The portable reverse-flow unit draws air in through the face, then exhausts HEPA-filtered air out through ductwork that can be connected to room exhaust or vented out through a window. It’s a fast and easy way to turn existing spaces into isolation areas.
