What is a two-stage rotary screw compressor?

A two-stage rotary screw compressor takes in atmospheric air but “shares the work” over two separate compression processes and cools it in between. The difference between the two is not the end result, rather the energy required to produce the end result.

Are rotary screw air compressors a good choice?

There are pros and cons to everything, and air compressors are no different. Both single-stage and two-stage rotary screw air compressors have their place in industry and plant managers are charged with making the right choice based on their unique needs and requirements.

What is a rotary screw air compressor?

Unlike reciprocating air compressors that use a cylinder and piston arrangement in a linear compression process, rotary screw air compressors use a pair of intermeshing screws (rotors) contained in a stator housing (airend), with an inlet port on one end and a discharge port on the other end.

Do you pay for a rotary screw air compressor?

You pay for the air compressor once, but you pay for the power to run that air compressor for its entire lifespan. Power costs represent up to 75% of the total cost of ownership of a rotary screw air compressor, and the energy savings over the life of a two-stage air compressor can be significant.

What is the difference between rotary screw air compressor and reciprocating air compressor?

Both have a place and there are some distinct differences between the two. Rotary screw air compressors often provide plants with the biggest opportunity for improvement and savings. The principle of rotary screw air compression is really no different than reciprocating (piston) compression.
