GAST Piston Air Compressor/Vacuum Pump

Gast 1/4 and 3/8 NPT air compressors / vacuum pumps are suitable for natural gas pipelines. They feature a thermally protected, shaded-pole motor for preventing accidents caused by overheating and have aluminium cylinders & heads for quick heat transfer. These pumps are equipped with sandwich valves to restrict foreign particles from lodging on valve seats.

Filter

Gast vacuum pumps produce air pressure or vacuum using a reciprocating piston. They operate continuously without oil and are employed in industrial applications like aeration, beverage dispensing and packaging.

Features

  • Gast vacuum pumps feature a thermally protected, shaded-pole motor for preventing accidents caused by overheating and have aluminium cylinders & heads for quick heat transfer.
  • These pumps are equipped with sandwich valves to restrict foreign particles from lodging on valve seats.
  • They utilise a crankshaft-driven cylinder & piston to compress the air at high pressures and deliver torque up to 2 HP.
  • These pumps employ positive displacement in which the pistons operate in small, indistinct bursts to increase or decrease the space that contains the air, causing the air to move through a one-way valve.
  • Gast rocking piston air compressors feature rocking piston design to provide consistent flow throughout the service life and oil-less permanent lubrication to offer smooth and quiet operation.

Working Mechanism

  • These type of pumps produce vacuum and compression through the movement of the piston sealed against a cylinder.
  • The piston is attached to the crankshaft via a connecting rod.
  • As the crankshaft rotates, the piston is pushed back-and-forth within the cylinder.

Standards and Approvals

  • CE Approved

Frequently Asked Questions

What are the different types of vacuum pumps?

There are many types of vacuum pumps, such as rotary vane, diaphragm, liquid ring, scroll and turbomolecular vacuum pumps.

What is a reciprocating air compressor?

Reciprocating air compressors (also known as Piston air compressors) are positive-displacement compressors that employ a crankshaft-driven piston and cylinder to compress the air. Successive volumes of air are confined within a sealed space.

What is the difference between a piston and a rotary compressor?

A piston air compressor is oil-cooled, which results in the discharge of oil residue when the compressed air is discharged. Whereas rotary air compressors are usually equipped with two interlocking helical rotors fit with a little gap between them and soaked in an oil bath inside a housing.

What are compressor pistons constructed of?

Piston Compressors are usually constructed of one of these two materials - cast iron or aluminium.
