Piston Air Compressor/Vacuum Pump

Piston air compressors or vacuum pumps are designed to provide compressed air as an energy source or transmit natural gas. Raptor Supplies offers a wide range of these compressors from brands like Welch, Gast and Thomas Pumps. They utilise a crankshaft-driven cylinder & piston to compress the air at high pressures and deliver torque up to 2 HP. These compressors are available in electric, shaded pole, capacitor start, open, permanent magnet and PMDC motor variants for prolonged life, having an oil-less or a rocking piston vacuum pump design.

Working Mechanism

  • Piston air compressor / vacuum pumps operations are based on the reciprocating piston within a cylinder principle.
  • The piston is linked to a crankshaft powered by an electric motor.
  • When the motor starts, the crankshaft begins to rotate, causing the piston within the cylinder to move back and forth.
  • The piston compresses the air in the cylinder as it moves towards the cylinder head. After that, the compressed air is stored in a pressure tank or reservoir.
  • When the piston moves away from the cylinder head, a vacuum is created in the cylinder to draw in the ambient air.

Frequently Asked Questions

Does temperature affect a piston air compressor / vacuum pump?

  • For air compressors, high temperatures can lead to a decrease in the compressor's efficiency and an increase in the risk of overheating.
  • For vacuum pumps, the main concern is low temperature which can lead to condensation and icing in the pump, this can cause damage to the internal parts of the pump and reduce its performance.
