Anemostat Multi-Vent Model MV-HEP room side, replaceable laminar flow HEPA filter modules shall be installed where shown on the drawings, and shall integrate with the ceiling type shown. For hard surface installations, multiple filter modules shall be attached directly to each other, as shown, to form a contiguous array of panels that creates a single, downward piston of laminar flow air, to provide particle control of the work space below. The perimeter edges of the module array shall include trim strips to conceal rough ceiling opening.

The non-aspirating laminar flow filter modules shall include a (top)(end) round inlet collar (suitable for attachment of flexible duct of the size shown on the plans) and a perforated face, to establish a unidirectional flow of air.

The filter module assembly shall include an integral knife edge for use with HEPA filter Gel seals. A pressure port shall be included to measure the HEPA filter pressure drop. A volume damper shall be located in the neck to assist in air balancing, and shall be adjustable from the room without removal of the face. Plug buttons shall be provided in the face for access holes.

The removable face shall be attached to the assembly with 1/4 turn fasteners and shall include closed cell gaskets. Stainless steel safety cables shall prevent accidental dropping of the panel. The face shall include hinges, in addition to the safety cables, to allow the face to swing down 90 degrees for cleaning.

(Optional) All filter modules shall include the Anemostat Light-Alert filter monitoring system.

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

Laminar flow filter modules shall be constructed from steel, stainless steel, or aluminum as indicated. 

The finish of the perforated face shall be (Arctic White baked-on epoxy) (304 stainless steel - #4 satin polish). The finish of the rear, dual chamber assembly shall be (Arctic White baked-on epoxy) (304 stainless steel – mill finish).
