What factors must be considered before purchasing air compressor pumps?

Users should check whether they require rotary or reciprocating type pumps and whether the applications require single-stage or multi-stage operation. Multi-stage pumps generally produce higher pressurised air than single-stage pumps.Specific applications require a specific amount of air pressure and airflow rate. Maximum air pressure and rate & volume of airflow offered by an air compressor pump should match the application before purchasing. CFM (cubic feet per minute) denotes the maximum quantity of air a compressor can produce at a preset pressure level.

What is the difference between 1 and 2-stage air compressors?

The basic difference between a 1-stage and 2-stage air compressor is the number of times the air gets compressed. Air is compressed once in a 1-stage compressor, while it is compressed twice (for doubling the pressure) in a 2-stage compressor.

Piston Air Compressors

Gast piston air compressors are positive displacement compressors which employs a crankshaft-driven piston and cylinder to compress the air. These vacuum pumps feature aluminium cylinders and heads having thermally protected, shaded-pole motors with superior torque start windings. Choose from a wide range of these piston air compressors, available in electric, shaded pole, capacitor start and open motor types.

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.

Features

Gast piston air compressors are equipped with a sandwich valve made of stainless steel to prevent the accumulation of contaminants on the valve seats.
They feature an aluminium cylinder head for abrasion resistance and installation in constrained spaces of automobiles.
These piston air compressor's head are thermally protected.
They feature Teflon-filled piston rings for minimum downtime, high wear resistance, low friction operation and broad temperature tolerance.
These piston air compressors have automatic thermal protection to eliminate overheating hazards and tolerates temperatures ranging from 32 to 100 / 32 to 104 degrees F.
They are available in capacitor start, electric, open and shaded pole motor variants.
