Abstract: A clean room filter array including a plurality of individual filter units arranged for delivery of filtered air to a clean room is supported by an individual suspension assembly including a fastener pin at outturned flanges of each filter unit that is unshared with any other filter unit so that the filter unit of a frame and fixed filter media is shiftable to and from the array independently of shifting the position or orientation of the other filter units or altering their respective suspension assemblies.

Abstract: A clean room ceiling filter system has a filter unit received by a filter unit receiving unit, the filter unit and filter receiving unit define cooperating latch and keeper structure that deflects into fastened engagement and releases from within the clean room by simultaneous pivoting of each latch member of each set of latch members. A tubular rod within the filter unit allows dispensing test material onto the filter media from within the clean room and adjustment of an air flow damper also from within the clean room.

Abstract: Clean room ceiling in which the individual filter units are suspended solely by unshared suspension assemblies so as to be self-supporting and readily installable and removable individually and free of grids and other multiple unit supporting expedients.

Abstract: A fan filter unit for clean rooms has baffle structures sized and placed to limit the paths of entry of air flow from the unit motorized fan to the outlet ports, the baffle structures extending for a vertical height sufficient to avoid reversal of air flow within the enclosure for lower energy requirements in the unit while controlling noise levels and keeping BTU output low.

Abstract: A clean room filter unit mounting system including a bracket, a bracket and fastener assembly, and individually mounted filter units. The bracket and fastener assembly includes a bracket having a relatively fixed member and a relatively movable member to allow misaligned mounting of parts such as the filter units in a clean room ceiling to fixed suspension rods without perfect registration of the bracket fixed member with the suspension rods, and a fastener able to pass through both bracket members in a first arrangement and to block such passage in a second disposition.
