Electro-air Cleaner Company Inc.

"In Greater Pittsburgh'* Representatives in Principal Cities
Electro-air Hi-C, "High Capacity" Electronic Air Cleaners have been developed for ease of installation, maintenance-free operation and high efficiency. The entire line features a self-adjusting, ballasted, single circuit and selenium rectifiers. All parts, including selenium rectifiers are guaranteed for five years.
All Electro-air equipment incorporates the patented "Inside Curve" Ioniser which means higher efficiency, reduced size of equipment, increased capacity and face velocity, and service-free operation. All sizes of Elec tro-air units are available with either vertical travel ing manifold or horizontal fixed manifold washing
systems.
The latest Electro-air engineering development is the new DetergentAdhesive System, Type "X", with "double action" DAX solution which is available with all sizes of Electro-air equipment. It is supplied as a "package" and is used to promote thorough washing and adhesive applica tion. DAX solution is injected into the wash water during the last Vs of the washing cycle, acta as a strong detergent, then dries and leaves an ad hesive coating on collecting plates and electrodes.
Electro-air Detergent-Adhesive System Type "X
"Boilt-up Line" equipment is manufactured in capacities from 10,350 cfm to 200,000 cfm for larger building areas. Each unit is made "to order" according to the specified height, width and cleaning capacity required, is assembled and tested at the factory, then match-marked, disassembled and shipped in well marked crates. "Built-up Line" units are also fur nished with "enclosures" complete with drain pans, fore and aft ducts, windowed access doors and complete wiring.
Electro-air "Built-up Line" Enclosure Unit
"Custom Line" units are furnished in capacities from 1,150 cfm to 21,360 cfm as complete "packages" and are designed for use in those cases where space is limited and access doors in ducts are not practical. Each unit is complete with the required number of collecting cells, drain pan, washing system and power pack. "Custom Line" Electro-airs are fur nished in either horizontal or vertical (up or down) air flow, and may be floor mounted or suspended.
Electro-air "Custom Line" Unit
' "Compact line" Electro-airs, are moderately priced and are designed for easy installation in homes and smaller commercial or industrial build ings which have forced air ventilation. They are available in fifteen models, both horizontal and vertical (down) flow in capacities from 800 to 9,600 cfm. Horizontal flow models may be either floor mounted or sus pended. "Compact Line" units include most features of larger "made-toorder" Electro-air models.
Electro-air "Compact Line" Unit
Electro-air Cleaner Company, Inc. also manufactures low cost uTec Line" units which are true electronic air cleaners (90 percent efficient as . determined by the National Bureau of Standards Dust Spot Test) for in stallation in small and medium size homes.

Evans Lifelong Air and Grease Filters All Aluminum . . . Every Part Precision Made
FILTER PACK HOLDS MORE GRAMS OF DIRT PER CUBIC INCH.
SEAL TIGHT HOLDING FRAME WITH PVC GASKET GIVES PERMANENT DUST TIGHT SEAL.
Abe* pboto shows neeUon of procUoa stamped (rid.
Strands and grids are scientifically sited and placed for holding
maximum dirt load. Filter pack has larger grid openings on sir inlet side progressing to smaller grid openings on air outlet
side. Prevents face loading and choke-on of air stream. Ac complishes uniform depth loading ail through the pack. Every grid, every strand does its part.
TURBULENCE AIR CLEANING ACTION.
Dirt is slammed into the flat strands of mesh where it is-caught and held by talon like edges of these grids. Precision stamped openings force air to travel many times filter depth from inlet to outlet side.. .. for high efficiency air cleaning.
LOWER AND SLOWER STATIC PRESSURE RISE PER GRAM OF DIRT LOAD.
Filter pack catches and holds dirt without strangling air stream. Filter remains in service longer: (1) without sharp increase in resistance (2) with fewer cleanings (3) with power costs held down.
HIGH VELOCITY APPLICATION ... UP TO 1,000 FPM.
Using turbulence air cleaning action (instead of screening or
straining action) makes Evans filters particularly well suited
to extremely high velocity requirements. The higher the
velocity . . . the harder dirt is'slammed into the
where
it is caught and held by the talon like edges of the strands.
Filter's efficiency rises as velocities rise.
DOUBLE ACTION ADHESIVE.
Works as adhesive while filter is in service. Becomes a detergent and helps wash filter when water is flooded on. IMPORTANT . . . When Evans filter fluid is used filters can be washed with tap water.
