Rotary sliding vane compressor screw compressor for sale LUY290D-21

A screw air compressor uses a rotary-type positive-displacement mechanism. They are commonly used to replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications or to operate high-power air tools such as jackhammers and impact wrenches.

Multi-stage, or two stages, compressors feature a series of cylinders, each a different diameter. Between each compression stage, the air passes through a heat exchanger, where it is cooled. 

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 faster recovery time and can handle more tools at once.

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.
