Pumps & Compressors

Air compressors are critical pieces of equipment on most jobsites, used to power tools and complete many tasks. ... One key difference is choosing between an air compressor that uses an oil-lubricated pump and one that utilizes an oil-free design.

Patented scroll wrap design with labyrinth seal provides superior performance and reliability Proprietary tip seal reduces air leakage while extending service intervals Normal maintenance can be completed without disassembling pump Integrated Design for Maximum User Benefits

No oil means that there is no oil for sealing the rotors and for cooling the compressed air, elements and rotors. ... The element is cooled by cooling water that flows through special pockets in the element casing.

The general mechanism of an air compressor is a piston or rotary element (e.g. rotary screw or vane) that draws in air, which is compressed into a storage tank. Naturally, since the piston or rotary element needs to move consistently and smoothly for this to work, it generally needs to be lubricated.

Rotary vane: Rotary vane pumps are comprised of a series of vanes that are mounted to a rotor that turns inside a cavity. As the vanes rotate, centrifugal force extends them from their individual slots, forming compression cells that get larger to draw air in from the intake and smaller to push air out the exhaust.

A vacuum pump is a device or device that USES mechanical, physical, chemical substance or physical-chemical strategies to pump air out of a container to get a vacuum.
