Air System Equipment Air Filters and Cleaners The Air-Maze Corporation 5202 Harvard Avenue, Cleveland, Ohio ENGINEERS AND MANUFACTURERS OF AIR FILTERS EXCLUSIVELY Direct Factory Representatives in All Industrial Areas. Distributors in principal cities and towns throughout the United States. During more than a decade devoted exclusively to air filter engineering and manufacturing, a great deal about the control and elimination of dust, pollens and grit has been learned by AIR-MAZE engineers. Their design and development of a unique type of filter element con struction, embodying distinctive advan tages, has been considered a worthy con tribution to the air filtering science and has resulted in wide acceptance of AIR-MAZE air filters in all fields of application. Efficiency--Tests under varying con ditions, both in laboratories and field oper ations, show air filtering efficiency of from 98.00 to 99.83 per cent with practical dust. No Clogging--Because AIR-MAZE panel filters are easy to completely clean and since the exact density enables uni form deposit of dust, no clogging can occur. Adaptibility--In addition to air condi tioning and power equipment installations AIR-MAZE panel filters are effectively .used in humidifiers, water eliminator units, paint spray-booths, oil separators, range canopies in kitchens, and other applica tions where specific problems and unusual requirements are easily handled by adapta tions of the panels. AIR-MAZE panels will be made to fit frames of existing installations and can be furnished with locking handles and latches, snap catches, or with Hanged edges and lift handles. S in. Thick Panel 4 in. Thick Panel AIR-MAZE Permanent Cleanable Panel Filters Note Advantages Made Possible by Air-Maze Scientific Construction: Costs Little to Clean--The separating layers and exact spacing of baffles permit free washing action between and around all baffles. Thus, cleaning and charging operations may be easily and economically performed. Great Dust Capacity--Unique design of the AIR-MAZE screen wire element provides a vast area of baffles on which collected material can become impinged; thus great capacity is assured. Vibration Proof--Vibrations in service cannot shake filter media out of position-- the uniform density remains permanently perfect; no replacements are necessary! AIR-MAZE Are Listed by Under writers* Laboratories--When serviced according to the methods recommended by the Underwriters* Laboratories, AIRMAZE pane! filters are approved as fire retardant air filters. Magnified Section of "Loaded" AIR-MAZE Air Filter Element. Note that dust has been quite evenly impinged on the wires. No obstructed spaces can be seen. This feature accounts for the Low Pressure Drop and Non-clogging characteristics ofAIR-MAZE TECHNICAL INFORMATION Sizes--All sizes and thicknesses are available; two and four inch thick panels are the accepted standard. Installations using large sizes of these permanent panels are surprisingly low in cost. Capacity--Recommended air capacity is 1J4 to 2Yi cfm per square inch. Thus, the capacity of a 20 x 20 in. panel is 600 to 1000 cfm. Normally, 2 cfm per square inch should be used. 862 Air System Equipment Air Filters and Cleaners The Air-Maze Corporation 5202 Harvard Avenue, Cleveland, Ohio Resistance--For 2 in. thick panels the resistance varies from 0.089 in. to 0.10 in. H,0 when handling 2 cfm per square inch of filter area (288 fpm velocity); and for 4 in. thick filters the resistance varies from 0.121 in. to 0.140 in. H,0 at 2 cfm per square inch (288 fpm velocity); the vari ation being in accordance with the differ ent types of filter media construction available. To obtain specific restriction data write for graph RE-2A. Construction--AIR-MAZE filters are of patented construction consisting of a maze of alternately placed and exactly spaced crimped galvanized wire screens of selected meshes; these are arranged with precision so as to create graduated and progressive density, and to positively em body the baffle impingement principle. The filter element is enclosed in a heavy gauge metalescent enameled steel frame having an open end to simplify servicing. EASY TO CLEAN AND CHARGE Cut-away View From a fiat sur face raise one end and let it drop sharply several times. This facilitates drainage. After cleaning and also after charg ing. set panel on edge, with open end down, to drain. Gleaning--Simply tap panel a few times on a hard surface to remove heavy accumulations and then wash under a stream of hot water or in a pan of hot water. Steam also cleans the panels quickly and effectively. Be sure filter is dry before charging. Charging--(For general applications) Spray both front and back of panel with just enough oil to coat the wires. Any inexpensive oil of S.A.E. 40 or 50 viscosity is suitable. An ordinary insect spray gun will do the work splendidly. Or, if desired, panel may be immersed^ in oil and then thoroughly drained. AIR-MAZE INSTALLATION FRAMES frames assure efficient, attractive installations. AIR-MAZE panel holding frames are constructed of metalescent enameled heavy gage steel having % inch flanged back edge. A thick felt lining on inside of flange insures against air leakage when panels are in place. One frame may be used alone in single panel installations, or a group of frames may be supplied, fixed together; thus a large bank of filter panels may be provided. Every frame section is fitted with snap catches as standard equip ment; a lift handle is installed on each panel. In determining frame sizes, ^ inch is allowed over the EXACT width, and h/z inch over the EXACT height dimen sions of the panels. These dimensions include frame edge, clearance and felt edge seals. Specify AIR-MAZE--for all air filter installations and you will be assured of efficient, economical performance. Write for specification bulletin CCC-69. Engineering Service Available--The Air-Maze Engineering Department will gladly offer installation suggestions for special air filter applications. Other AIR-MAZE Products--In ad dition to the panel types, Air-Maze Cor poration also manufactures a complete line of circular shaped air filters for use in various Railroad, Industrial and Auto motive applications. Literature Available--Catalog GPC740 describing industrial types "A," "B," Greastop, and Kleenflo panel filters.
