(IN STOCK NOW) The FASU range are filtered air supply units, designed to provide clean, quiet air. FASUs are commonly used in environments with installed air conditioning systems which don’t supply fresh, filtered replacement air. The FASU range incorporates a powerful single phase centrifugal fan with three different motor speeds, protected by a powder coated, corrosion resistant steel casing. This range of fresh air supply units are designed to provide air quietly and efficiently, making them well-suited to school rooms, offices, and various other general buildings.
