Air System Equipment Air Filters and Cleaners Continental Air Filters, Inc. 2524 Helm Street Louisville, Kentucky THE CONTINENTAL AUTOMATIC SELF-CLEANING AIR FILTER -- now being used by many nationally-known companies (names on request)--has three entirely unique features: Revolutionary new filter media, Ferris-Wheel action, and positive, effective self cleaning. THE FILTER MEDIA The filter media consists of double-corrugated strips of aluminum or other metal, placed in non-nesting relation ship to form a honeycomb structure. The main air stream is divided positively into approximately 2300 small air streams per square foot of filter surface. An extremely high efficiency in dust removal is obtained due to the many changes in direction and the turbulence caused by air streams crossing each other while traveling in different directions. The resistance to air flow, however, is lower than in comparable air filters. FERRIS-WHEEL ACTION The filter cells, suspended from chains, move in FerrisWheel fashion without changing their relative positions. The air enters and leaves the same side of each filter cell, regard less of whether it is in the front or back section of AIB the filter curtain. Thus dirt cannot he blown off n_uv\ the dirty side of a cell, back into the clean-air stream. POSITIVE SELF CLEANING After the individual filter cells have traveled down into the viscous liquid in the tank, a cam action causes each cell to be held in a horizontal position for approximately 30 minutes. The dirty cell is fully submerged at this point, and the 30-minute submergence breaks the surface tension of.the liquid which binds the accumulated dust to the filter media. Then, when the. cell is released, it quickly drops to a vertical position, and this movement through the\Iiquid washes the dust particles out of the cell. Cleaning Efficiency: 91.3 per cent, determined in test by Professor F. B. Rowley, University of Minnesota, v under A.S.H.V.E.

The alternate layers of flat and Herring bone-Crimp fine wire screen results in Low Pressure Drop (0.12 in. W.G. clean at 519 fpm), Greater Air Delivery (1200 cfm at 519 fpm through 20 x 20 x 2 in. unit-permitting equal filter and coil area and eliminating most V-bank installa tions), Higher Efficiency (improved per formance up to velocities as high as 750 fpm), Larger Dirt Holding Capacity (from 30 per cent to over 125 per cent more filtering media per unit), and Easier Cleaning (cold water hosing cleans thor oughly. Far-Air Filters can be cleanedin-place . . . they do not have to be removed from their holding frames). Based on the recommended net face velocity of 519 fpm, Far-Air Filters de liver 50 per cent more air with the same blower power. This effects a saving in both initial costs and maintenance costs as only 23 the filter area need be installed and maintained. PROGRESSIVE LOADING Farr Company has originated a simple procedure for testing air filters iiydace to determine . the comparative efficiency. Write for information regarding this test. A complete testing laboratory is main tained for all types of research work in the field of air cleaning. Trade Mark registered. As entering orifices of Far-Air Filters are loaded, air direction changes, flowing past the front loaded surface and pro gressively loading the clean screen mesh that remains. Greater free area permits a larger dirt load with lower pressure drop. For full information about Far-Air. Filters write: Farr Company, Dept.
