Industrial Air Compressors
CompAir oil-free screw air compressors

Where contaminated compressed air can result in expensive product spoilage, you can be rest assured that a CompAir oil-free compressor will eliminate oil-carryover in the compressed air. In addition, the removal of oil from the compression process enables compressed air users to operate with maximum environmental efficiency.

Industries, both large and small, rely on CompAir for a supply of consistent high quality compressed air including automotive, aviation, petro-chemical, power generation, shipping and utilities. In situations where the compressed air comes into direct contact with the products being manufactured: for example food and drink, pharmaceuticals, electronics and textiles CompAir compressors have been enabling users to meet their quality and production needs for many years.

The new DH-Series offers a cost-effective oil-free solution

We have extended our oil-free offering with the introduction of a new range of water-injected single screw compressors. Designed for applications where there is a need for high-quality 'active' air - air that comes into direct contact with the process it serves. The series is launched with 15, 22 and 37kW models.

Product manager Andy Pulley comments:
"In active air applications, quality of the air is key. High technology industries in particular, including precision engineering, pharmaceutical, food and drink, electronics, chemicals and healthcare, all demand higher quality air. They are also looking for the lowest ownership and operating costs. The DH single-stage water-injected rotary series is not only the most efficient range of oil-free rotary products available, it offers reduced energy and maintenance costs and hence a lower life time cost than any other compressor in its size range."

A Reliable and Efficient Heart

At the heart of the compressor is an innovative single screw compression element, featuring a single main rotor with 6 flutes meshing with a pair of 11 tooth gate rotors, that is proven in thousands of installations.

Compression takes place in two chambers above and below the main rotor, as a result compression loads are balanced and bearing loads are significantly reduced. The low bearing loads extend compression element life and significantly reduce lifetime operating costs.

Water injected into the compression element provides lubrication, sealing and cooling. The superior cooling properties of water allows the compressor to operate at a low temperature providing near isothermal compression, low power consumption and class leading efficiency levels. A reverse osmosis membrane cartridge filters the injection water entering the compressor; as a result the water is always maintained at a high purity level.
 

100% Oil-Free Construction

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

100% oil-free compressed air - guaranteed

Non-contact, non wearing labyrinth seals prevent bearing lubricant entering the compression chamber. Thrust balance pistons equalise the loads across the heavy duty. low friction ball and roller bearing, allowing each bearing to achieve its optimum life expectancy.

Market leading efficiency

The CompAir compression element design sets the industry standard for energy efficiency. The rotor casing feature generously sized liquid cooling passages for even heat dissipation, enabling closer tolerances to be used for high compression efficiency.


Extended service life

The CompAir D series features an electric motor driven oil pump that delivers full lubricant pressure prior to starting thereby extending the operational life of the compression element and its bearings.

Two stage inlet filtration protects against the ingress of airborne particles into the compression element.

Compact design

The fully silenced, free standing CompAir D series compressor package includes drive motor, coolers, inlet filtration and silencing system, integrated compressor controls and all service connections.

Simplified maintenance

Servicing costs and downtime are kept to a minimum with; a grouped service area, simplified access for cooler cleaning, hinged service doors all round and an 8000 hour service interval.
 

CompAir control system

CompAir's microprocessor-based compressor management system simplifies operation and allows instant review of status. Comprehensive control, condition monitoring, protection and remote control facilities are built into the system.

As demand for compressed air can vary, CompAir D series compressors are fitted with a regulation system that efficiently matches output to demand. Discharge pressure is monitored via a pressure transducer and the compressor automatically loads and unloads, minimising energy consumption.
