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