Air Saver Unit Valve Reduces Energy Use in Air Blow Applications

Pulsing technology reduces the air consumption by up to 50%

Parker’s Air Saver Unit is a valve that converts a continuous air blow to a pulsed air blow without the need for any other external control. Air is blown with a series of ON and OFF pulses. When the blow is OFF, there is no air consumption. By using switching valve technology, the Air Saver Unit can reduce the air consumption by up to 50%, which translates into:

  • Large reductions in air consumption.
  • Savings in compressor power consumption.
  • Reduction in plant CO2 emissions.
  • Big contribution to energy-saving activities.
  • Improved efficiency.

When you consider that air blowing accounts for up to half of all compressed air used in plants, the potential energy, and cost savings is considerable. In the example outlined below, the application of Air Saver Unit on four nozzles with a one minute below per four-minute cycle operating for three shifts, five days per week saved plant operators $3,500 annually.

Value of Parker air saver unit in sample application

The reduction in air consumption doesn’t necessarily mean a decrease in blow performance. The Air Saver Unit uses switching valve technology when the pulsed air blow created by the unit hits the work repeatedly. As a result,  the efficiency of the air blow is increased, and air consumption is decreased. 

The following applications will benefit from a high-performance air saver unit valve the most:

  • Cleaning blows before assembly
  • Swarf removal
  • Ionizer dust removal
  • Cooling and drying applications
  • Liquid removal after the manufacturing process
  • PET bottle transfer
