LPAC is classified as which type of compressor?

Explanation:
LPAC is a rotary compressor. It’s designed to deliver a steady, large volume of air at a relatively low pressure, which is ideal for starting and pneumatic needs in a gas-turbine system. A rotary type provides smooth flow with fewer pulsations and a compact package, which is important in aircraft and turbine installations where reliability and size matter. Among rotary designs, the single-screw configuration is used for LPAC because of its simple, robust construction and good performance at low to moderate pressures. It efficiently generates the required low-pressure, high-volume air without the pulsations that come with reciprocating machines, and without the high-speed, high-pressure characteristics of centrifugal compressors. Diaphragm compressors aren’t typically used for this service due to their limited flow and different applications. So, LPAC is best described as a rotary single-screw compressor.
