Application

The F21 Air Intake Filter is recommended for use on turbines, engines, blowers, and compressors where controlled air filtration is required.

Design

A rigid housing designed to accept standard 24" x 24" filter elements. Various types of elements are available to provide filter efficiencies to meet the needs of engines, blowers, or compressors.

Filter housings are available to accept either a single filter element or two filter elements in series. View Filter Elements here.

Internal design provides a safeguard to prevent small size foreign objects from entering the air intake passageway when filters are removed.

Special designs available upon request.

Construction

Welded sheet and plate steel construction. Metal joints are sealed to prevent dirt and air from by-passing the filter element. Surfaces are prime coated, followed with a final coat of machinery enamel. Flanges are drilled to match 125 lb. American Standard Flanges. Weatherhoods are included. Special finishes, or materials are available at extra cost.
