Cleanair™ Fan Filter Units are self-contained, motorized Supply Air Modules equipped with either HEPA or ULPA filters. Our FFU's can be used in either horizontal or vertical flow positions, wherever clean air is needed. The clean air fan filter module includes a fan shroud, a fan/motor mount, a centrifugal fan, a fan motor, and a HEPA filter, the fan shroud having an air inlet and two inclined ends, the fan/motor mounted below the air inlet on the fan/motor mount, the centrifugal fan blowing air radially towards the fan shroud, the HEPA filter constituting the air outlet.

Fan Filter unit is generally used to supply purified air to the clean room for manufacturing semiconductor, liquid crystal, etc. The installation space is the system ceiling grid. For a large clean room, the number of required FFU is from several hundred to several thousands.
