Accredited by the Better Business Bureau and headquartered in Englewood, Ohio, Eaton Compressor & Fabrication ships air compressors and accessories across the United States. The company offers a selection of electric-powered rotary screw compressors, with options including single-, dual-, or three-phase rotary swing arms and variable speed drives. Sold under the Polar Air brand name, Eaton Compressor’s “Nex-Gen” rotary screw compressor has recently been redesigned with ROTORCOMP air ends and sound attenuating cabinets.

Available in both oil-injected and oil-free

models, rotary screw compressors use two

rotors, or helical screws, to compress air for

a variety of industrial purposes. These two

“male” and “female” rotors are designed to

fit each other with absolute precision. When

the screw compressor rotors begin to turn,

air is sucked in through an outside vent to

get “trapped” between the rotors.

Industry experts turn to the rotary screw

compressor for its highly efficient

functionality and its largely noiseless

operation. Because it employs a

continuous compression modality, it runs

smoothly and quietly.
