When placed on special floor support stands or suspended from ceiling frames, and fitted with vinyl curtains, they form an enclosure with an air cleanliness level of better than Class 100 in accordance with AS 1386.1.Motor blowers draw in ambient air through prefilters which remove all particulates 5 micron and larger. The prefiltered air is introduced to the laminar flow enclosure via final HEPA filters in the underside of the unit. The average air flow velocity within the enclosure is maintained at 0.35 m/s with uniformity of ±20%. Alternative air velocity levels for specific applications are readily achievable.
