Reciprocating Single Acting Air Compressors Manufacture Coimbatore

Reciprocating Single Acting Air Compressors Reciprocating single acting compressors are generally of one-stage or two-stage design. Compressors can be of a lubricated, non-lubricated or oil-less design. In the single-stage compressor, air is drawn in from the atmosphere and compressed to final pressure in a single stroke.

  • The Single-stage compressors are generally used for pressures of 70 psi (pounds per square inch) to 135 psi.
  • In the two-stage compressor, air is drawn in from the atmosphere and compressed to an intermediate pressure in the first stage. Most of the heat of compression is removed as the compressed air then passes through the intercooler to the second stage, where it is compressed to final pressure. Two-stage compressors can include two cylinder designs.
    Single and two-stage reciprocating compressors are frequently used in auto and truck repair shops, body shops, service businesses and industrial plants. Although this type of compressor is usually oil lubricated, hospitals and laboratories can purchase oil-less versions of the compressors.

This type of compressor develops pressure through a reciprocating action of a one-piece connecting rod and piston. The piston head rocks as it reciprocates. These compressors utilize non-metallic, low friction rings and do not require lubrication. The rocking piston type compressors are generally of a smaller size and lower pressure capability.

The diaphragm compressor develops pressure through a reciprocating or oscillating action of a flexible disc actuated by an eccentric. Since a sliding seal is not required between moving parts, this design is not lubricated. Diaphragm compressors are often selected when no contamination is allowed in the output air or atmosphere, such as hospital and laboratory applications. Diaphragm compressors are limited in output and pressure and they are used most often for light-duty applications.
