The axial-flow compressor has two main elements: a rotor and a stator. The rotor has blades fixed on a spindle. These blades impel air rearward in the same manner as a propeller because of their angle and airfoil contour. The rotor, turning at high speed, takes in air at the compressor inlet and impels it through a series of stages.

A single-stage reciprocating compressor is a type of compressor in which the gas or air is compressed in a single stage. This compressor uses a single cylinder and a piston for the compression of air. And also, the air is compressed only one time. The body of this compressor sets according to the arrangement of the piston and cylinder.
