Our ceiling-mounted Criti-Clean Ultra fan filter units have the highest CFM output on the market (up to 1200 CFM for our 48″x24″ model), are energy efficient (only 42 watts at 90 FPM velocity/ 450 CFM), and are incredibly quiet (only 45 DBA at 90 FPM, 58 DBA at 1100 CFM).
Plus, these units are easy to retrofit into existing spaces due to their low plenum height – just 13.7″ on the air supply unit and 15.8″ on the reverse-flow unit. They connect to building ductwork and are easy to install in either a ceiling grid system or a plaster/hard ceiling using our innovative surface mount clamps.
The units have also passed the stringent seismic testing requirements of the California Department of Health Care Access and Information (HCAI), formerly known as OSHPD, allowing them to be used in seismic zones. You can download the full HCAI report below and watch a video of one of our shake tests here.
For permanent installations, our ceiling-mounted FFU offers the industry’s highest output of up to 1200 CFM. Plus, it’s easy to retrofit into existing spaces due to its low plenum height – just 13.7″ on the air supply unit and 15.8″ on the reverse-flow unit. The FFUs connect to building ductwork and are easy to install in either a ceiling grid system or a plaster/hard ceiling using our innovative surface mount clamps.
Our new Criti-Clean Ultra has the highest CFM output on the market (up to 1200 CFM for our 48″x24″ model), is more energy efficient (only 42 watts at 90 FPM velocity/450CFM), and is incredibly quiet (only 45 DBA at 90 FPM, 58 DBA at 1100CFM). Plus, the new uit has all the same great features and options as the original.
Models include:
Air Supply Units
The air supply Criti-Clean Ultra continually produces a non-aspirating, low velocity, uniformly distributed, downward moving “piston” of HEPA-filtered air, as is used in hospital operating rooms and other critical environments. Multiple units can be linked together to produce one large combined laminar mass. Air recirculating units are also available.
Reverse Flow Units
Our reverse flow FFUs create a negative pressure environment that draws air up and out of a room, removing airborne contaminants via the unit’s built-in HEPA filter, and then discharges clean air. Reverse-flow units are typically used for patient isolation.
