Air System Equipment Air Recover (mtBzn an Charles E. Maiming Co. ------------------- J 4135 Brownsville Road Pittsburgh 27, Pexma. AIR PURIFICATION AIR RECOVERY SYSTEMS REFILLABLE ACTIVATED CARBON RECOVERY CANISTER I, rn--TYPE "C"--CANISTER, a perforate metal cylinder filled with granular car bon (for 15 to 35 cfm each with recom mended maximum of 25 cfm). Made up of one perforate metal cylinder within another, with the side walls of the two forming an open area which is filled with granular activated carbon. The top is completely sealed with a cap that en closes both the inner and outer shell. Air flows through the cylindrical side wall and carbon bed, into the hollow center of the inner cylinder--then down PERFORMANCE CHART C-4 Cfm Pressure Loss* (Inches W.

The Canisters may be set on the mani fold plate in any arrangement that best suits the requirements and available space.' Canisters and/or manifold plate can be furnished in stainless steel, brass or aluminum for special installations. NU-AIR TYPE "A" AIR RECOVERY UNIT The Type "A" panel Air Recovery unit handles from 700 to a maximum of 1000 cfm. For use in removing odor and gaseous impurities where those concen- trations-are light to medium. The shape of the carbon bed offers a great exposed area to the air flow for maximum effi ciency. The carbon bed is formed by two parallel sheets of perforated metal, fashioned in a series of S-curves, com prising the Surface through which the air flows. Both types of equipment can be used in single or multiple units for required capacities. Complete technical data available in oeiv' bulletin 1S-CX, 1B-DX by writing the manufacturer.

Correctly sized fibers mean peak efficiency . . . minimum resistance. "Depth-load ing" extends filter life. THE FILTER Dust-Stop Air Filters are impinge ment-type filters constructed of glass fibers which are non-absorptive, fire proof and will not shrink or swell. Fibers are coated with a non-evaporating odorless adhesive which effectively traps dust, lint and pollen. Dust-Stops are replacement-type filters and should not be laundered. Uses--Dust-Stop Filters may be used at approach velocities up to 450 fpm with out impairment of their high efficiency characteristics but with higher resist ances. Maximum permissible resist ance of filters is in. water gage. Resistances Resistance--inches, water gauge 300 fpm 450 fpm 1 in. filter .080 .170 2 in. filter .135 .300 In cases where velocities approach 450 fpm, care should be taken to see that fan capacity is adequate to overcome; increased resistances. Cfm Capacities--Rated capacities of standard 20 in. x 20 in. Dust-Stop Filters are 800 cfm at 300 fpm velocity and 1250 cfm at maximum permissible velocity of 450 fpm. DUST-STOP FILTER FRAMES --^o.-kjvup vliter -frames are designee for the convenience of the engineer ir constructing filter banks. Metal frame is of universal style, suited to use in Bat or "V" banks. Designed-in, self-lock ing device ' permits fast, economical assembly. Made to take 2 in. or 4 in depth of standard 20 in. x 20 in. or 20 in. x 25 in. filters. Black painted or galva nized finish. Front, back and side angle uprights for V-bank assembly are also offered in 20 in. increments up to 160 in. length.
