Air System Equipment ci^ners Owens-Corning Fiberglas Corporation Toledo 1, Ohio OH'EN'S-CORNIXO Fiberglas AIR FILTERS WHAT THEY ARE--Fiberglas* Dust-Stop Air Filters are replaceable, impingement-type filters. Dust-Stops are con structed of fibers of glass that are non-absorptive, do not shrink or swell. WHERE DUST-STOPS ARE USED-- Dust-Stop Filters are used in all systems in which there is a mechanical movement of air--central heating, ventilating and air-conditioning systems, and forced warm air furnaces. Composed of nu merous fibers of glass coated with a viscous adhesive, Dust-Stop Filters catch the dust particles as the air moves through them. ADVANTAGES OF DUST-STOPS--One of Dust-Stops' great est plus values is fire safety. The fibers cannot burn and will withstand temperatures of 1,000 F. Being glass, the fibers are inorganic, chemically stable and resistant to corrosive vapors. A new, improved dust-catching adhesive is sprayed on the fibers for longer life with no loss of efficiency. . All Dust-Stop Fil ters are now listed by Underwriters' Laboratories. No special machinery , is necessary to install Dust-Stops. Air filtering costs are further cut by Dust-Stops' high capacity to clean the air 6f dust, dirt, lint and pollen. Dust-Stops are readily adaptable to practically any system. Their low cost and easy installation make Dust-Stops the engineer's preferred filters. FACTS ABOUT DUST-STOPS--Avail able in two standard types: (1 inch and 2 inches). Both types are made in many sizes to fit practically every installation. Each filter is faced with a metal grille and bound on the edges with a fiberboard frame. WHERE TO BUY DUST-STOPS--Check yellow pages of your phone book for name of the Dust-Stop distributor in your vi cinity. If unable to locate a distributor write Dept. 44, Owens-Corning Fiberglas Corporation, Toledo-1, Ohio. "FIBERGLAS and DUST-STOP are trade-marks (Rea. U. S. Pat. OS.) of Owens-Corning Fiberglas Corporation for products made of or with fibers of glass. 1236, Air System Equipment raters Research Products Corporation Madison 10, Wisconsin AIR FILTERS FOR HEATING AND VENTILATING Grease Filters for Kitchen Exhaust Systems--Paint Arrestor Pads RP AIR FILTERS Controlled turbulence design is pro vided in every RP filter. Scientifically staggered baffles cause thousands of sharp reversals of air flow in the filter. Media gradation, insures RP depth loading, an important longevity feature. Air borne particles are centrifuged against the baffles and are held by adhe sive in the air filter and by the viscous qualities of the particles, themselves, in the grease filter and paint arrestor appli cations. Constructed of slit and expanded ma terial, RP filters are uniform in con struction and performance. ODOR REMOVAL Exclusive RP Combination dust and odor removal is available in the D-O Air Filter--a replaceable filter--and with D-O Kote, the dust and odor removing ad hesive for application to RP alumaloy washable filters. WASHABLE REPLACEMENT All RP replacement filters employ a fiber media. The oversize RP "SelfSeal" idea was developed due to the ease and safety in handling the exposed media. Soft, resilient, and nonfractur ing, the media only is sold in a refill pad for the famous RP Fiber Self-Seal, Air Filter for central systems and units and the RP Snap-In Grid for central systems (illustrated). The filters and pads as well as a conventional cardboard frame filter are available in one and two inch thickness. RP Paint Arrestor Pads, stop and hold overspray in spray booth operation. RP Paint Arrestors cut labor costs and maintenance down-time necessary with conventional paint spray booths. RP Paint arrestors have high overspray removal efficiency, versatility in applica tion and low first cost. The RP Alumaloy E Z Kleen Air Filter is an economical selection for many applications.. Like all RP washable air filters, this filter is ex tremely easy to clean. RP Alumaloy Industrial air filters are multi-velocity filters, which have ex tremely low initial resistance and slow build-up resistance. Holding frames for filter banks, combination lift and lock handles, lift handles and water soluble filter coat adhesive are available. Efficiency in excess of 99 per cent on grease vapors, gleaming appearance, ease of cleaning and light weight have made RP Alumaloy Grease Filters a volume performance leader in its field.
