Manufactured under licence by Farr Co, Mfg, Ltd,, Montreal, Canada New York FAR-AIR FILTER AND HOLDING FRAME A high velocity, low resistance, viscous impingement unit for industrial and commercial applications. Available in a wide range of types and sizes for dirt, lint, grease, entrained water, ink, paint, etc. Herringbone-crimp media design assures higher performance, larger dirt holding capacity, lower pressure loss, easier cleanability and reduced main tenance costs. Standard interlocking holding frames are 16 gage steel. Various protective coatings available. FAR-AIR CAPACITIES Recommended net face velocity is guide in estimating FAR-AIR Filter 519 fpm although velocities up to 700 requirements. 4 in. filter thickness has fpm may be used.

AirJSystem Equipment AirFm* HOW TO SPECIFY STANDARD TYPE 44 FILTERS & FRAMES Filter shall be permanent, impinge ment, washable, all metal, panel type. Media shaii be zinc electroplated, 14 mesh steel screen, arranged in alternate layers of flat and herringbone-crimped screens, so that at no point is air flow restricted to flow through the screen, 4 layers of each per inch, J-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 cfm per square inch of net face area. Holding frames shall be factory built on 16 gage steel "T" section, with felt air seal, interlocking edges, and filter lock ing 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. ROTONAMIC SELF WASHING FILTERS ROTONAMIC The Rotonamic is a compact, multiple tube; cyclonic type air cleaner with continuous dirt removal by air bleed. Efficiency averages 98 percent on 5 to 10 micron dust of 2.5 specific gravity. Efficiency is even higher on larger parti cles or on denser material. Rating of 20 x 20 x 4in. panel is 1000 to 2000 cfm depending on available pressure. Ap parent straight through air flow requires no difficult change in duct direction. Bleed off piping is simple. Deflecting vanes form a high velocity vortex in each tube. Internal reversal of the direc tion of flow doubles the cyclonic action, . producing the high efficiency. *ucac completely automatic units was! and re-oil themselves on any frequency cycle desired. Each is made up iron 4 in. thick corrosion-resistant filters it 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 ant inexpensive. ENDLESS GREASE ELIMINATORS FAR-AIR Endless Grease Eliminators 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 one-sided and twosided models in sizes to meet any cfm requirement. Full catalog and technical informa tion on any FAR-AIR product is avail able on request. 1321
