Compressed air filters designed to be the most energy-efficient in the world are being marketed in Australia by the company that pioneered such filters, domnick hunter.

The OIL-X EVOLUTION filters use aerospace technology to optimise air flow paths through the filter’s housing and element to significantly reduce air turbulence and pressure losses, reducing system operating costs.

Installed in a compressed air system using an 185kW compressor, for example, the innovative design could save the user up to 60 per cent per filter in energy consumption compared with a traditional filter, says the company’s Business Development Manager John Davis.

To be launched in Australia as part of a global launch in September - and shown at the Queensland Manufacturing and Technology Exhibition 19-21 October – the unique design guarantees compressed air quality and offers optimum protection of downstream equipment, processes and workplace environments, says Mr Davis.

”This new domnick hunter OIL-X EVOLUTION range of compressed air filters has been designed from the outset to meet current and forthcoming requirements for compressed air quality. Design of the compact filter has focused on efficiency-critical areas, such as air flow management, filtration media selection and construction and efficient removal of coalesced liquid”

“domnick hunter invented the coalescing compressed air filter in1963 and this all-new high-efficiency filter is truly a generational evolution that results in the most energy efficient filter of its type in the world,” said Mr Davis, whose company is a leading international specialist in filtration, separation and purification technology, including refrigerant and desiccant compressed air dryers and complementary products in its complete filtration programme.

Aerospace technology has been applied to eliminating all unnecessary pressure losses in the new filters. These losses would otherwise consume energy as the pneumatic system worked harder to compensate.

Air streams are channelled through the filters in a way that reduces turbulence and pressure losses, including the use of full radius blended bends, diffusers and turning vanes that reduce a 90-degree inlet corner into a number of smaller, more efficient, corners.

OIL-X EVOLUTION filters also employ a flow distributor to ensure the air stream is evenly distributed throughout the filter element for maximum filtration performance and energy efficiency.

The advanced design means the performance of OIL-X EVOLUTION filters exceeds the latest International ISO 8573.1 air quality standard. The filters’ efficiency has been verified not only by domnick hunter, but also independently confirmed by testing at Northumbria University.

With nine new International patents pending, OIL-X EVOLUTION filters have been designed to provide a very low initial saturated pressure loss which stays low throughout their 12-month guaranteed life, he says.

To achieve this, the filter media selected for OIL-X EVOLUTION is a borosilicate glass nanofibre with 96 per cent open area or voids volume, providing an extremely high dirt holding capacity. A special oleophobic coating actively repels oil and water, ensuring the open area is maximized for dirt entrapment.

The surface area of the cartridge has also been maximized with deep pleat media beds, which provide surface areas up to five times greater than filter elements using standard wrapped construction. This allows overall filter size to be reduced and ensures pressure losses start low and stay low.
