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, baked enamel finish.
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. The following chart is a twice the pressure loss of the 2 in.

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 flow restricted to flow through the screen, 4 layers of each per inch, 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, 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.
KOTONAMIC 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 4}j| in. 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.
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.
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 sizes and types to meet any cfm requirement.
