Parker Hannifin Air Saver Units cut energy consumption by halfParker Hannifin is unveiling its innovative Air Saver Unit, which can reduce air consumption by up to 50 per cent and improve efficiency in air blow applications.

Did you know that air blowing activities consume for almost half of all compressed air used in plants? 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 very easy to install. At plants using electrically operated solenoid valves to control air blowing, the units can be quickly and easily retrofitted to straightaway deliver a reduction in air consumption with no significant system changes such as 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. Go to to learn more.
