Piston compressors for the highest pressures
For more than 120 years Reavell has built high-pressure piston compressors for air and gases. Every block is designed and manufactured in its own factory in Redditch, UK, with no bought-in assemblies from other manufacturers.

Set the required final pressure and flow. The selector compares 29 blocks from the Reavell catalogue and shows the ones that reach the duty point.
Cooling
3 models reach this point
Indicative calculation from catalogue data at atmospheric inlet. Flow depends on speed and drive. With elevated inlet pressure (booster) the flow is much higher.

Where reliability and pressure are critical
Reavell has dedicated designs for each field. Pick a field to see the recommended models.
Industrial air and gas
Configured and custom-built packages for leak testing, autoclaves, wind tunnels, cylinder filling, laser cutting, turbine blow-out in pumped-storage hydro plants and recovery of expensive helium.
- Up to 600 kW for air and up to 260 kW for gases
- Zero-loss booster up to 18 bar inlet pressure
- HAI version on anti-vibration mounts, no special foundations
- HQI version with sound-attenuated enclosure for installation in any workspace
Example: Reavell 5337 in an ATEX zone of a refinery, with a plate heat exchanger that recovers 70% of the absorbed power as heat.
Piston technology that keeps oil and gas in
Each stage is designed for its own pressure. The result is minimal blow-by past the pistons and best-in-class oil carryover.
Low-pressure stages
- Iron alloy bores to Reavell's own specification, plateau honed
- Iron piston rings with optimised geometry
- Unchromed rings for maximum heat transfer
- Targeted lubrication for maximum efficiency
High-pressure stages
- Hardened and polished steel bores
- Polymer piston rings with few wearing parts
- Torus lubrication system on the final stage
- Retained plunger for fast maintenance
- ATEX T2All designs are ATEX assessed and can be supplied with certification.
- 3.1 certificateMaterial certificates for pressure-retaining parts for full traceability.
- Down to −10 °COperation at low ambient temperatures, sump heater above 5 kW.
- DNVType approval for engine-start compressors.
Fast maintenance, long service life
Critical parts are easy to reach, so the compressor is back in operation quickly. Factory service kits cover everything from an oil change to a full overhaul.
