We undertake work for most of the UK's major Gas users and specialise in all aspects of gas handling


Low-pressure compressors

We offer a wide range of low-pressure oil-lubricated rotary screw compressors, rotary vane compressors and oil-free rotary screw and oil-lubricated and oil-free piston compressors for all kinds of commercial and industrial uses.  Typical low-pressure compressor applications include:

  • Industrial manufacturing
  • Steel production
  • Aerospace
  • Power stations
  • Marine
  • Military
  • Oil & gas
  • Garage compressors
  • Light industry compressors

1 Oil-injected rotary screw compressors

Rotary screw compressors are efficient and long-lasting and can easily be controlled to use no more power than needed.  They have many advantages:

  • Long service life, even when used continuously
  • Heat can be recovered from the hot lubrication oil
  • Modular manufacturing approach for maximum flexibility
  • Can easily be sized to suit the required output
  • Choice of fixed-speed motor or innovative switch reluctance drive system
  • Digital system for precise pressure control
  • Soft starting and stopping to reduce stress

We offer oil-injected rotary screw compressors which are based on a modular design for flexibility and cost-efficiency.  You can take a standard machine and add an integrated dryer and a variable drive system, or for premium efficiency, a larger air-end. 

A refrigerated dryer can be integrated into the package to condense excess moisture out and protect the air distribution network.

Efficiency, reliability, economy and quality without compromise

Rotary screw compressors can be sized to suit the required output, and can be driven by either a fixed-speed drive motor or our innovative switched reluctance drive system.  The volume flow can be precisely controlled to meet changing demands, so you use only the energy required to do the job and no more.

2 Variable-speed rotary screw compressors

  • Use only the energy required to do the job - can be run at 20% of load to save energy

3  Rotary vane compressors from Hydrovane

Hydrovane, part of the CompAir group, has been designing and manufacturing rotary vane compressors for more than 40 years.  

Rotary vane compressors have the advantage that they are of simple construction, so they are cheap and easy to maintain and service.  They also give higher pressure than screw compressors and will routinely operate at up to 10 bar.  They are less suitable for arduous and prolonged use such as may be necessary in double-shift and 24-hour industrial environments.

The simple, robust design of Hydrovane rotary vane compressors makes them versatile, powerful, reliable and cost effective.  Rotary vane compressor technology is ideal for many light industrial applications - Hydrovane rotary vane compressors are found in trains, ships, engineering workshops, distilling, brewing, packaging sites and in large and small industrial units throughout the world.

Hydrovane rotary vane compressors are quiet enough in operation to allow them to be installed right alongside your equipment.  Most models are available either as open units or fitted with enclosure panels, which further reduce noise levels.

The Hydrovane range

The Hydrovane range of rotary vane compressors extends from 1.1 to 75 kw, with flow rates from 0.12 M³ per minute (4 cu ft) to 13.4 (474)

  • Compact design for a wide range of applications including auto, car body repair shops, dentistry, packaging and machine tools
  • Small integrated design - fits anywhere
  • Available free-standing or receiver-mounted
  • Continuous run or stop-start control
  • Low noise, vibration-free

Variable-speed rotary vane compressors

  • Variable speed precisely matches compressor speed with air demand
  • Directly driven at low speed for maximum reliability
  • Consistent pulse-free supply of quality air
  • Intake modulation combined with Hydrovane REVS energy vent minimises energy costs

4 Oil-free rotary screw compressors

We supply oil-free screw compressors to deliver anything from 5-2000 cfm.  Oil-free screw compressors are needed for applications where oil contamination must be rigorously avoided, such as medical facilities, labs and pharmaceutical manufacturing.  Instead, lubrication, sealing and cooling are all provided by a film of water.

The superior cooling properties of water allow the oil-free compressor to operate at a low temperature, providing near isothermal compression, low power consumption and class-leading efficiency levels.

Low operating temperatures and bearing loads allow maintenance-free sealed bearings to be used, removing the need for lubricating oil.  100% oil-free compression is therefore guaranteed and the maintenance and environmental costs associated with oil and filter changes are eradicated. 

5 Piston compressors

Piston compressors are the best option if you’re looking for the lowest-cost compressor for periodic light use.  Piston compressors offer a simple, robust and functional design, providing a dependable and efficient compressed air supply.  Available in oil-Lubricated and oil-free format, air receiver mounted, with refrigerant dryer, mobile or stationary, enabling you to configure your individual compressor solution according to your specific requirements.
