FFU fade
Ceiling-Mounted Criti-Clean Ultra Fan Filter Units (FFUs)

For permanent installations, our ceiling-mounted FFU offers the industry’s highest output of up to 1200 CFM.

Mobile Criti-Clean Ultra FFU

The Portable Reverse Flow unit can be plugged into a standard electrical wall outlet and placed anywhere on the floor of the isolation room. It draws air in, then exhausts HEPA filtered air out through ductwork connected to a room exhaust, return grille, adjacent space or through a window. Openings for ductwork must be sealed to prevent leakage and maintain room pressurization. The unit features a push/pull handle and swivel casters for easy movement.
