Maximize Efficiency with Positive Displacement Compressor

Product Details: Positive displacement compressors are mechanical devices that increase the pressure of a gas by reducing its volume. They operate by drawing in a discrete volume of gas and then forcing it out at a higher pressure. Common types include reciprocating piston compressors, rotary screw compressors, and rotary vane compressors. Reciprocating piston compressors use a piston driven by a crankshaft, while rotary screw compressors use two meshed rotating helical screws. Rotary vane compressors employ vanes that slide in and out of a rotor to compress air[2][3][5].
