What is a 2 Stage Air Compressor

Lubricated-Reciprocating-Industrial-Air-Compressor

The main difference between single and two stage compressors is the number of times the air gets compressed between the inlet valve and the tool nozzle. In a single stage compressor, the air is compressed once; in a two stage compressor, the air is compressed twice for double the pressure. By increasing the number of cylinder stages and pressure, these machines work more effectively with a faster recovery time, and can handle more tools at once.

How does a 2 stage air compressor work?
Multi-stage, or two stage, compressors feature a series of cylinders, each a different diameter. Between each compression stage, the air passes through a heat exchanger, where its cooled. Cooling the air reduces the amount of work necessary to compress it further. In a two-stage compressor, air is then forced into an additional chamber where its pressurized.

When to use a 2 stage air compressor
There are benefits to selecting a two stage air compressor, however, they’re not necessarily the right choice for every application. Generally speaking, single-stage compressors are best for light-duty, intermittent use applications, in which pressure requirements don’t exceed 100 PSIG. Two-stage compressors offer better value and reliability for continuous use applications, such as auto repair and manufacturing.
