Rotary air compressor or reciprocating air compressor?

 
There are far more than two types of air compressor available on the market, but in terms of basic ‘operating system’ the choice effectively comes down to rotary or reciprocating. Here’s what that means.

Selection of Air Compressors

Rotary and reciprocating air compressors

Rotary air compressors generate pressure using two interlocking screws (rotors) which take the air coming through the inlet valve, and generate pressure by reducing its volume. Reciprocating air compressors generate pressure by using pistons rather than rotors.

Which is better?

Confusingly, it depends. If you’re operating in a workspace which needs its air compressors to work 100% of the time, rotary or screw air compressors are likely to be a far better bet, because they’re better able to work without a break. Reciprocating air compressors are a better choice for intermittent duty cycles, but even here, a rotary system could be the more efficient in terms of energy consumption.

Design matters

The crucial deciding factor in determining whether a rotary or reciprocating air compressor will be more effective for your business is system design. It’s very easy to lose the theoretical efficiency advantages of a rotary system in an inefficiently designed system. That’s why it’s essential to seek expert compressed air system design.
