**[PART 2 - PRODUCTS]{.underline}**

**2.01 [ACCEPTABLE MANUFACTURERS]{.underline}**

> A. Terminal HEPA Filter Modules manufactured by one of the following:
>
> 1\. Flanders Filter, Co., Inc.
>
> 2\. American Air Filter.
>
> 3\. Filtra Systems
>
> 4\. Approved Substitute

**2.02 [MATERIAL]{.underline}**

> A. Steel: Galvanized in accordance with ASTM A386 or ASTM A525, G-90
> coating, or finished with baked-on enamel; thickness in accordance
> with USS gauges.
>
> B. Stainless Steel: Type 304, conforming to ASTM A167 or ASTM A666;
> thickness in accordance with USS gauges.
>
> C. Aluminum Sheet and Plate: 3003-H14 alloy, conforming to ASTM B209.

**2.03 [EQUIPMENT]{.underline}**

> A. General
>
> 1\. Provide a \"throwaway\" type HEPA filter.
>
> 2\. Use a design air flow of 100 fpm face velocity.
>
> B. Housings
>
> 1\. Provide housings with features indicated below.
>
> a\. Use 14 gauge aluminum.
>
> b\. Seal airtight at factory.
>
> c\. Design the unit to fit into a suspended 1-1/2-inch (in.), T-bar
> ceilings with 2 foot (ft.) by 4 ft. sealed grid.
>
