Filter Holding Frames and Fasteners

Models 9HF-xxxxx

General

Flanders Type 9 Holding Frames are used to con- struct built-up filter banks for upstream or down- stream access using ASHRAE rated filters. Type 9 frames will accommodate 1”, 2” or 4” panel filters including metal washable filters. They are also suit- able for bag filters, self-supporting rigid filters and disposable type carbon elements. A filter-to-frame seal is effected by a factory-installed gasket and positive-sealing fasteners.

Options

The standard frame is nominal 3” deep and con- structed of 16 ga. galvanized steel. Type 304 stainless steel is an available option. Frames are also available in nominal 2”, 4”, and 6” depth. Actual depth is 1/8” under nominal size.

Installation Consideration

Type 9 Frames can be assembled with pop rivets or nuts and bolts. Prior to assembly, all sides should be caulked with a non-hardening compound to pre- vent air bypass. Filter banks three frames high or higher should be strengthened with 3” wide 16 ga. stiffeners between each vertical row.

Fasteners

Flanders offers several types of fas eners for use with Type 9 Frames. Refer to the Fastener Selection Chart on the rever e ide of this sheet to select the appropriate fastener.
