FATA THE COMPANY: The American Air Filter Company, Inc., is recognized in ternationally as an authority on air filtration and dust control. In 30 years, its leadership and scientific "know how" have been responsible for installations of AAF equipment in every industrial ized part of the world. Because its con tinuous research, high engineering stand ards and exclusive specialization have been consistently maintained, AAF equipment is used by leading companies in nearly every industry and is specified by leading architects and engineers for use in commercial and industrial air conditioning. The American Air Filter Company)^ Inc., manufactures a complete line of air|| filtering and dust control equipments?? A few representative types are shown?!; here. AAF's years of experience and the scope of its knowledge dealing with the elimination of air-borne particles io 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 con trol, or its Herman Nelson Division (see pages *118-119) on heating or ventilat ing problems. AAF AIR CLEANING PRODUCTS Electro-Matte Self-Cleaning Electronic Precipitator--The Electro-Matic Precip itator 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 cleaning, minimizes the need for personal attention and permits continu ous high-efficiency operation. It also allows the Electro-Matic filter to be built in standardized self-contained sec tions, easy to install and with all exposed parts of the filter casing electrically grounded for the protection of operating personnel. Send for Bulletin No. 50. ROLL-O-MATIC Renewable Media Fil ter--An automatic air filter featuring a low cost, renewable media filtering cur tain 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. Intro duction of clean material to maintain desired operating resistance is controlled by an automatic time switch. ROLL-0MATIC's maintenance-free operation provides continuous, high efficiency cleaning at less than half the operating cost of a disposable type filter of equal capacity. Send for Bulletin 48. American Air Filler Co., Inc, Air System Equipment Air Filters and Cleaners EleclroCdl Electronic Filter Electro-PL Electro-matte Filter Multi-Duty Automatic Filter Electro-Cell Electronic Filter--A plate type electronic precipitator offering sim plified design, improved performance and maintenance advantages. Built in verti AMER-glas Replaceable Unit Filters. A new viscous impingement type for eliminating atmospheric dust from forced air heating systems. The highly efficient cal sections 2-ft and 3-ft wide. Hinged filtering media consists of continuous, ionizers extend the full height of the sections for easy access. Collector as semblies may be removed for individual cleaning--washed in place manually--or, with the addition of Type "H" Washer, cleaned automatically by traveling water sprays.
