General catalog also available on request. micron diameter, has rated efficiency over 90 per cent, as tested by the Na tional Bureau of Standards Discoloration Method. Collects smoke, fumes, pollens, and soot. AUTOMAZE AUTOMATIC AIR FILTER AIR FILTER PANELS Available in metal washable, viscous im pingement types, and dry disposable types. Dry `filters also available with washable strainer-type filter element. ELECTROMAZE ELECTRONIC AIR FILTER Where continuous operation without servicing is required, the Automaze "pulse action" automatic self-cleaning filter should be used. It combines a double filter panel curtain witb a positive effective panel cleaning action to provide the best in viscous impingement air filtration with a minimum of mainte nance. New self contained drive mecha nism and unitized control system simplifies installation. Standard Auto maze filter media is satisfactory for most installations, but other media types are available for special applications. ACCESSORIES Super-cleans air. Has semi or completely automatic vertical spray washing sys tem. Removes particles as small as 0.1 Cleaning tanks, holding frames, com plete assemblies for range canopies, viscous adhesive coatings, spray guns, etc. are available for complete installa tion and service Requirements. . 1318- Air System Equipment ^ American Air Filter Company, Inc. 673 Central Avenue, Louisville 8, Ky.

AAF AIR CLEANING PRODUCTS Electro-Matic Self-Cleaning Electronic Precipitator--The Electro-Matic Precip itator is an automatic electronic pre cipitator combining advanced principles of electronic air cleaning with an ex clusive self-cleaning principle. It elimi nates the necessity of shutting down the filter for manual cleaning, minimizes the need for personal attention and permits continuous high-efficiency oper ation. It also allows the Electro-Matic filter to be built in standardized selfcontained sections, easy to install and with all exposed parts of the filter casing electrically grounded for the protection of operating personnel.

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-OMATIC'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 848. 1319
