Montreal AIR FILTERS (formerly Aircor) Permanent-CIeanable GREASE FILTERS AIRSAN AIR FILTERS Industrial Domestic Commercial Airsan's expanded metal face plate acts as a lint arrestor to provide easier clean ing and servicing. It distributes air evenly over entire filtering area provid ing high filtering efficiency and dust holding capacity with low resistance. Media is viscous type, permanent, cleanable, and is constructed of multiple layers of galvanized wire mesh to give maximum air resistance. All Airsan Filters have full bronze welded corners, galvanized steel frames and drain slots for quicker, easier cleaning.

Plants: Louisville, Ky., and Moline, HL In Canada: Darling Brothers, Ltd., Montreal, Quebec MC 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 equipment. 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 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 con trol, or its Herman Nelson Division (see pages 1146-1147) on heating or ventilat ing problems. REPRESENTATIVE AAF PRODUCTS ELECTRONIC AIR FILTERS: For air cleaning problems requiring super-clean air AAF has developed three types of high-efficiency electronic filters. The complete line now available is the re sult of more than ten years of basic research and experimentation with elec tronic precipitation. It includes the self-cleaning Electro-Matic, the wash able Electro-Cell with removable collec tor plates, and the Electro-PL with the replaceable Airmat Paper medium. Electro-Matic Self-Cleaning Electronic Filter--The Electro-Matic filter is anautomatic electric precipitator combin ing advanced principles of electronic air cleaning with an exclusive self-cleaning principle. It eliminates the necessity of shutting down the fil ter for manual cleaning, minimizes the need for personal attention and permits continuous highefficiency operation. It also allows the ElectroMatic filter to be built in standardized self-con tained sections, easy to install and with all ex posed parts of the filter casing electrically grounded for the protec tion of operating person nel.
