Powerex® Oil-less Reciprocating Piston Pumps


The oil-less composite piston slides up and down within a low friction, wear-resistant aluminum cylinder, compressing air on the upstroke. The discharge air is cooled via an air to air after cooler. The multi-finned compressor cylinder is cooled by a dedicated fan (2 through 15 hp) as well as the fan blades on the flywheel. Compressors are single stage 1 through 3 hp and two stage 5 through 15 hp.

Benefits:
  • No oil anywhere
  • Composite piston reduces bearing heat
  • Dual cooling flywheel and fan
  • Corrosion resistant coating extends valve and ring life
  • NFPA 99 compliant
