Specification
1.0 General 
1.1 - Unit shall be ducted high efficiency ceiling module consisting of anodized aluminum frame, a galvanized back plate, 41-mm filter pack, polyurethane encapsulating sealant and dual access ports. Maximum module depth shall not exceed 4.73”.
1.2 - Sizes shall be as noted on drawings or other supporting materials.
2.0 Construction
2.1 - Filter housing shall be constructed of an anodized aluminum frame mated with a galvanized steel back plate. It shall be designed for installation into a T-Bar ceiling grid system.
2.2 - The media pack shall have a maximum depth of 41-mm (1.61”) and shall have an efficiency of (95 @ 0.3 micron, 99.99% @ 0.3 micron, 99.9995% @ MPPS).
2.3 - Pleat spacing shall be by continuous glass filament separators to prevent media-to-media contact and promote uniform airflow through the media pack.
2.4 - The media pack shall be completely encapsulated in a polyurethane sealant creating a rigid self-supporting pack. The sealant shall be low out gassing, fire-retardant and self-extinguishing. 
2.5 - The module shall include an adjustable airflow diffusion disc that is adjustable from the room side through an access port to allow balancing across multiple units throughout the clean room.
2.6 - A second port, accessible from the room side, shall be provided to allow aerosol test challenge measurement or pressure drop.
2.7 - Housing shall be supplied with a (“10”, 12”) collar that includes an integral continuous raised ridge for duct side connection to air system.
2.8 - Unit shall include an epoxy-coated steel face screen with a minimum 62% open area.
3.0 Performance
3.1 - The filter shall be identified on a label indicating minimum efficiency, tested airflow and pressure drop. The unit shall be bar code serialized for individual unit identification.
3.2 - The module shall be listed by Underwriters Laboratories as UL 900.
3.3 - Manufacturer shall provide evidence of facility certification to ISO 9001:2008.
