172 Air System Equipment American Air Filter Company, Inc, 673 Central Avenue, Louisville 8, Ky. American An Filter of Canada, Ltd., Montreal, P. Q. THE COMPANY: The American Air Filter Company, Inc.', is recognized internationally as an authority on air filtration and dust control In 30 years, its leadership and scientific "know how" have been responsible for installa tions of AAF equipment in every industrialized part of the world. Because its continuous research, high engineering standards and exclusive specialization have been consist ently maintained, AAF equipment is used by leading com panies in nearly every industry and is specified by leading architects and engineers for use in commercial and indus trial air conditioning. The American Air Filter Company, Inc., manufactures a complete line of air filtering and dust control equipment. A few representative types are shown here. AAI^s years of experience and the scope of its knowledge dealing with the elimination of air-bome particles in' every form insures maximum efficiency in application, design, manufacture and installation . . . with a minimum of field engineering. Write AAF on all problems of air filtration and dust control, or its Herman Nelson Division on heating or ventilating problems. AAF AIR CLEANING PRODUCTS Electro-Matfe Self-Cleaning Electronic Precipitator--The Electro-Matic Precipitator is an automatic electronic pre cipitator combining advanced principles of electronic air cleaning with a special self-cleaning principle. It eliminates the necessity of shutting down the filter for manual clean ing, minimizes the need for personal attention and permits continuous high-efficiency operation. It also allows the Electro-Matic filter to be built in standardized self-con tained sections, easy to install and with all exposed parts of the filter casing electrically grounded for the protection of operating personnel Send for Bulletin No. 250. ROLL-O-MATIC Renewable Media Filter --An automatic air filter featuring a low cost, renewable media filtering curtain of bonded glass fibers supplied in convenient roll form. The media, mounted at top of filter, moves down the face of the ROLL-O-MATIC and is re-rolled on a driven spool at bottom. Introduction of clean material to maintain desired operating resistance is controlled by an automatic time switch. ROLL-O-MATICs maintenance-free opera tion provides continuous, high efficiency cleaning at less than half the operating cost of a disposable type filter of equal capacity. Send for Bulletin 248. Air rate. American Air Filter Company, Inc. 673 Central Avenue, Louisville 8, Ky. American An Filter of Canada. Ltd.. Mnxnwi,, p, Q. 173 The Electro-Cell is a stationary plate-type electronic precip itator available in both conventional and high-velocity designs for application on a wide range of dirt concentrations. Cell construction assures simplified installation-and ease of main tenance. Collector assemblies may be removed for individual cleaning--washed in place manually--or, with the addition of Type "H" Washer, cleaned automatically by traveling water sprays. Write for Bulletin No. 252. Electro-PL--A special dry-type electronic air filter with charged Airmat collector element which combines air filtra tion and electronic precipitation in a single unit. Gives inter mediate efficiency at lower cost, when the need for superdean dr is not indicated. However, it has twice the efficiency of uncharged dry-type filters. Available in Straight Bank or "V" arrangement to meet virtually any space or capacity requirement Send for Engineering Bulletin No. 257. Motti-Daty Automatic Filter provides outstanding features of performance and design and wdl accommodate either ar mored screen panels or die stamped louvre panels available in three types. Offers advantage of uniformly constant air supply, fixed operating resistance and automatic operation. Ideal for ventilation and air conditioning service. Available in any size or capacity. Send for Bulletin No. 241-A. ROLLOTRON Renewing Filtering Media. This unit com bines a dry-plate electrostatic precipitator with an automa tically renewing filter media, for the ultimate in air filtration. Dust particles are attracted to the dry plates of the ROLLOTRON'S precipitator section where they adhere to one an other until the build-up becomes great enough to be carried by the air stream to the storage section. Here they are trapped in a blanket of media which is pulled across the face of the filter section from top to bottom, at a rate sufficient to main tain operating resistance at a desired level. Maintenance in volves ooly the simple replacement of a soiled media roll with a new one. Write for Bulletin 249. Airmat Type PL-24--Airmat filters use standard Airmat me dium, renewable after collecting dust load. Used both for comfort and industrial air conditioning. Available with unit frames to be set up to meet any capacity requirement or space condition. Send for Bulletin No. 230. Type HV-2 Filter: A high capacity, low-resistance unit de signed for velocities up to 500 fpm. Special pyramid pocket media design eliminates through-air passages and gives uni formly high efficiency over wide range of air velocities. HV-2 has large dust capacity, long life, and decided advantages where space is limited. Available in three designs. Write for"' Engineering Bulletin No. 203.
