Better under pressure.
Air compressors, nitrogen generators and vacuum systems. Supplied, installed and serviced from our 6,000 sq ft factory in High Wycombe.

Three ways to move air, gas and vacuum
We stock and supply thousands of products from industry-leading brands. Many lines can be bought direct from the website and delivered across the UK.
Air compressors
CompAir, Hydrovane, Champion and Bambi ranges, fixed speed and regulated speed, plus oil-free machines from bench units to 160 kW.
Air treatment
Filters, three types of dryer and condensate management, so water and oil never reach your process.
Energy and controls
Audits, leak detection, variable speed drives, heat recovery and flow monitoring with clear payback periods.
On-site nitrogen generators
Make nitrogen from your own compressed air with PSA or membrane generators, instead of buying cylinders.
Vacuum pumps and blowers
Rotary vane, claw, liquid ring and screw pumps, plus side channel and rotary lobe blowers, from Elmo Rietschle.
Pneumatics and spares
Authorised Parker Store. Cylinders, valves, FRLs, fittings and tubing, plus service kits and consumables at the trade counter.
Supplied, installed and serviced by the same people.

Questions we hear often
Do you only service the compressors you supply?
No. We service CompAir, Hydrovane, Ingersoll Rand, Gardner Denver, Atlas Copco, Kaeser, Champion, BroomWade and many others, regardless of who supplied the unit.
How often does a rotary screw compressor need servicing?
Rotary screw compressors commonly need servicing every 2,000 hours or annually, whichever comes first.
What does compressor hire cost?
Hire units start from £10 per day, up to 1,000+ cfm, to keep production running while a machine is repaired.
Do I really need an oil-free compressor?
We will tell you honestly whether your application needs oil-free compression, or whether filtration is an appropriate and more cost-effective alternative.
