Reciprocating 0.5 To 15 HP Two Stage Low Pressure

The technology and development engineers at oil-free technology INDO-AIR did extensive research on the critical components of the compressors to operate in oil free operating conditions.

Oil Free Technology

The technology and development engineers at oil-free technology INDO-AIR did extensive research on the critical components of the compressors to operate in oil free operating conditions.

The result is the new series of reciprocating compressors with Reliable Oil Free Technology employing special material to withstand extreme pressure & temperature operations.

Salient Features

  • Sealed and high temperature resistant pre-lubricated bearings.
  • Well designed cooling system of air cooled inter/after coolers.
  • special material piston ring which retains its properties under high temperature working conditions.
  • Piston ring outer surface always in contact with the cylinder bore even after thousands of hours of running and corresponding wear ensuring unchanged pumping up time.
  • Special material piston ensures the retention of cylinder bore finish in adverse temperature condition and expansion of piston.

Proven Rof Technology

Reliable Oil Free (ROF) technology Gives 100% oil free air and Thousands of hours of continuous running without any seizure.
