Manufactured under license by Control Equipment Co., Ltd., Montreal, Canada FAR-AIR* FILTERS FOR ALL TYPES OF INDUSTRIAL USE New York THE FAR-AIR FILTERING PRINCIPLE . . . Herringbone-Crimp Media Design FAR-AIR Filters obtain maximum efficiency through their herringbonecrimp media design. Zinc electroplated wire mesh is formed in alternate layers of flat and herringbone-crimp to make channeled, triangular openings facing the incoming air flow. Design allows greater air flow, turbulence and effi ciency. Dirt builds up in the mesh on the entering side which diverts the air Progressive Loading Feature flow through the channels to clean mesh where the filtering process continues. The accompanying diagram of progres sive dirt loading shows why FAR-AIR filters have higher performance, larger dirt holding capacity, lower pressure loss, easier cleanability and reduced maintenance costs. FAR-AIR CAPACITIES . . . Recommended face velocity is 519 fpm although velocities up to 700 fpm may be used. Higher air velocities than recommended results in.greater pressure loss and a shorter service period. Ve locities lower than 350 fpm are not recommended. The following chart can be used as a guide in estimating FAR-AIR Filter requirements. 4 in. filter thickness has twice the pressure loss of the 2 in. thick ness. NETT FACE VEL.

Box 10187, Airport Station LOS Angles 45, Calif. Manufactured under license by Control Equipment Co., Ltd., Montreal, Canada New York HOLDING FRAMES AND DIMENSIONS FAR-AIR holding frames are made from 16 gage steel and have a baked enamel finish. Felt stripping around the inside flange assures tight filter fit and prevents air by-pass. Frames are interlocking and easily bolt together to form a rigid framework. Calking be tween frames in a bank is unnecessary. Clips hold filters firmly in place. Brac ing is not needed in banks up to 5,fi)ters high by 6 filters wide. Instruction sheets are included in every shipment.

Sizes over 25 in. X 30 in. are not recommended, however, as they are difficult to handle. HOW TO SPECIFY STANDARD TYPE 44 FILTERS & FRAMES Filter shall be permanent, impinge ment, washable, all metal, panel type. Media shall be zinc electroplated, 14 mesh steel screen, arranged in alternate layers of flat and herringbone-crimped screens, so that at no point is air now restricted to flow through the screen, 4 layers of each per inch, i-in. rod reinforced, and enclosed in a frame of 16 gage steel with flush mitered corners. Resistance to air flow of a clean filter shall not exceed 0.12 in. w. g. at 3.6 efm per square inch of net face area. Holding frames shall be factory built on 16 gage steel "T" section, bonderized and bake enameled, with felt air seal, interlocking edges, and filter locking device; Filters shall be Far-Air Type 44 and frames shall be Far-Air Standard Inter locking as manufactured by Farr Com pany, Los Angeles 45, California. SELF WASHING FILTERS GREASE ELIMINATORS These completely automatic units wash and re-oil themselves on any frequency cycle desired. Each is made up from 4 in. thick corrosion-resistant filters in combination to meet any cfm require ment. Washing water and contami nated oil is immediately flushed away, eliminating messy sludge and oil sumps. There is no oil entrainment. Each unit has a safety deluge valve that auto matically prevents fire from passing the unit. Installation is simple and inexpensive. FAR-AIR Grease Eliminators, consist of two standard filters in a special adapter with drip pan.. These units halt the deposit of highly combustible grease and lint in the air ducts, reduce maintenance, protect blower and fan, provide better ventilation and sanita tion. Available in sizes and types to meet any cfm requirement. Full catalog and technical information on any FAR-AIR product is available on request ... or see Sweet's Architec tural File. 1233
