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 epoxy-coated face screen. 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 hot melt media 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 a fixed airflow diffusion to promote uniform airflow across the media pack.
2.6 - Housing shall be supplied with a (“10”, 12”) collar that includes an integral continuous raised ridge for duct side connection to air system. 
2.7 - The module shall include an epoxy-coated steel face screen with 62% open area to promote uniform airflow on the exiting side of the module. 
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.
