Rotary compressor are suitable for High pressure and low discharge as compare to the dynamic (centrifugal compressors).

Rotary-screw pressure is used where large volume and high pressure is needed.

Rotary (screw) compressors are suitable for large discharge of air at high pressure. [Ref: Wikipedia].

I thought there is a wrong answer. Because the rotary compressor is the type of positive displacement compressor. And the property of positive displacement is highly discharge pressure and low discharge.

I thought you mean screw compressor by "rotary compressors", which actually can be used at low pressure but wouldn't be suitable for large discharge.

Centrifugal compressor always give more flow then pressure, where reciprocating compressor gives more pressure and less flow.
