Model HCR High Capacity Radial Diffusers

Anemostat Model HCR High Capacity Radial diffusers shall be installed where shown on the drawings. The diffuser shall incorporate a flat, non-aspirating face flush to the ceiling or mounting surface.

The diffuser shall be of the (surface mounting type) (lay-in inverted tee bar type), and shall be fully assembled at the factory consisting of a hinged removable face, a gasketed frame body, and sub-duct. Field assembly shall not be required.

The supply duct shall connect to a top duct collar on the diffuser. (Optional) The supply duct shall connect to a side or end duct collar on the diffuser, of the size and location as shown on the plans.

The diffuser air discharge shall be a radial, outward contiguous air stream that forms and fills a (90°) (180°) arc in continuous planes, perpendicular to the longitudinal axis of the diffuser. The air discharge stream shall allow installation of continuous rows of diffusers that abut each other without air stream interference between adjacent diffusers. Each diffuser shall incorporate a manual pattern controller to trim adjust the pattern. The controller shall be accessible from the room, without the need to remove the face.

The diffuser face shall be hinged to the diffuser back pan and attached to the back pan in the plane of the ceiling with 1/4 turn quick lock fasteners. Stainless steel safety cables shall prevent the face from falling during face removal. The diffuser face shall consist of a discrete pattern of perforations and directional apertures that cause the air discharge to flow in radial jets that coalesce to form the contiguous air flow pattern. Multi-blade, grille-like assemblies requiring field adjustment of each individual blade to obtain desired pattern are not acceptable. 

The radial diffusers shall be constructed from steel, stainless steel, or aluminum, as indicated.

The finish of the face assembly shall be (Arctic White baked-on epoxy) (304 stainless steel - #4 satin polish). The finish of the back pan assembly shall be (Arctic White baked-on epoxy) (304 stainless steel – mill finish).

(Optional) A volume balancing damper shall be factory installed integral with the diffuser and shall be adjustable from the room side.

HCRF Radial Hepa Filter Modules

Anemostat Model HCRF High Capacity Radial Hepa Filter Modules shall be installed where shown on the drawings. 

The diffuser shall be of the (surface mounting type) (lay-in inverted tee bar type), and shall be fully assembled at the factory consisting of a hinged removable face, a gasketed frame body, and sub-duct. Field assembly shall not be required.

Multi-blade, grille-like assemblies requiring field adjustment of each individual blade to obtain desired pattern are not acceptable

The unit shall house a HEPA filter (field installed after diffuser installation), replaceable from the room side, without the need to disconnect or disturb the supply duct system. The filter shall be retained in the housing by means of quarter turn latches and cap screws. Retaining methods with exposed bolt threads are not acceptable. The housing shall also include a combination stiffening frame and knife edge to provide leak-free attachment of the HEPA Filter with gel seals.  Each diffuser shall include a volume adjustment damper. For diffusers with top inlets, the damper shall consist of a perforated disk, with the adjustment rod extending through the center divider of the filter. A removable / replaceable rubber expansion plug shall seal the damper rod opening. For diffusers with end inlets, a cable shall operate the damper for volume adjustment. 

The radial diffusers shall be constructed from steel, stainless steel, or aluminum, as indicated.

The finish of the face assembly shall be (Arctic White baked-on epoxy) (304 stainless steel - #4 satin polish). The finish of the back pan assembly shall be (Arctic White baked-on epoxy) (304 stainless steel – mill finish).

(Optional) Each diffuser shall include the Anemostat Light Alert filter monitoring system.

(Optional) A volume balancing damper shall be factory installed integral with the diffuser and shall be adjustable from the room side.

(Optional) All filter modules shall include an integral Aerosol Injection system to simplify field verification and certification.
