An air compressor is one among the major energy consuming efficacies in any industrial operation and is generally classified in two categories. The classification is based as per their construction and operation facets. The two main categorization of Air Compressor are: 1. Positive Displacement Type 2. Dynamic Type 1. Positive Displacement Type Air Compressor Positive displacement kinds of compressors are those, who automatically transfer a set volume of air into a reduced volume. The steady volume could be delivered by the compressor while it is operated at a set speed. The discharge pressure is decided through the system load states. If the utilization of air is more then the discharge pressure falls below the set cut-off pressure and compressor works on the load condition. Air Compressor Sales Michigan depends upon the consideration mentioned. This kind of air compressor can be further categorized as: a. Reciprocating Air Compressor In this type of air compressor, the compressed air is generated by the to and fro movement of piston inside the cylinder or also known as compression chamber. b. Rotary Air Compressor In this kind of air compressor, air is compressed by two inter meshing or rotating motors. And rotary compressors could further be classified as rotary Screw Compressor and rotary vane compressor. 2. Dynamic Type Air Compressor The dynamic type air compressors mechanically pass on the velocity to the air. This action is generated by the Impellers rotating at a very high speed, in enclosed casing. The air is compelled into an increasingly reduced volume. The volumetric flow varies inversely with the differential pressure transversely the compressor. This kind of compressor could also be classified further as Centrifugal Air Compressor, Axial Flow Air Compressor and Roots Blower Compressor. a. Centrifugal Air Compressor In a Centrifugal Air Compressor, an Impeller is built up on a shaft and positioned within housing, containing of a diffuser, a volute and an inlet duct. b. Axial Flow Air Compressor The Axial Flow Type Air Compressor is fundamentally a large capacity, high speed machinery with features quite different from the centrifugal air compressor. Every air compressor installation Michigan stage contains two rows of blades, one row is stationary and the other one rotates. c. Roots Blower Compressor This kind is usually known as blower. The discharge air pressure obtained from this kind of machine is very low. The Discharge Pressure of 1 bar could be attained in Single Stage and pressure of 2. 2 bars are attained from Double Stage. This is the instance of Positive Displacement Compressor in Rotary Type Air Compressor.
