Criti-Clean-Ultra fan powered laminar flow HEPA filter diffuser

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. 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.

Optional Features:

  • Built-In LED Lights – eliminate the need for additional light fixtures, help maximize the use of ceiling space and do not interfere with the airstream like hanging lights.
  • UV-C Radiation Module – assists in sterilizing particulates in the FFU’s air stream and also disinfects the HEPA filter to help protect against viruses, bacteria and mold.
  • Needlepoint Bipolar Ionization Module – produces a stream of ions that create free radicals, which attach themselves to airborne pathogens and rob them of hydrogen to deactivate them. The larger clusters of particles are also more easily trapped in the HEPA filter.

Criti-Clean Ultra: We re-designed and re-engineered our popular Criti-Clean fan powered laminar flow HEPA filter diffuser to maximize both CFM and energy efficiency. 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/ 450 CFM), and is incredibly quiet (only 45 DBA at 90 FPM, 58 DBA at 1100 CFM). Plus, the new unit has all the same great features and options as the original.
