Efficiency gains, which result in savings being made, is usually the ideal situation that a company is looking for.

Parker Hannifin’s latest device promises to provide both efficiency gains and cost reductions. The Air Saver Unit can reduce air consumption by 50% and Improve air efficiency in air blow applications.

Air blowing activities are responsible for almost half of all compressed air used in plants. So to help reduce this resource burden, Parker Hannifin’s Air Saver Unit uses pulsed air technology.

At its core is a switching valve that converts continuous air blow into pulsed air blow without the need for any additional external control. Put simply, it creates air that is blown in a series of high speed on and off pulses; when the blow is off, there is no air consumption, resulting in fewer tank recharging cycles.

Aside from a sizeable reduction in air consumption, the Air Saver Unit offers other major advantages that include savings in compressor power, a reduction in overall CO2 emissions and a significant contribution to energy-saving activities.

The Air Saver Unit is also extremely easy to install. At plants using electrically operated solenoid valves to control air blowing, the units can be quickly and easily retrofitted to deliver a reduction in air consumption with no significant system changes – like PLC program reconfiguration.

For plants using manual ball valves, there are also passive versions of the Air Saver Unit series; these do not require any electrical power.

In total there are seven models in the Air Saver Unit range, offering flows (at 5-bar) from 150 to 15,000 l/min.
