Advanced Concentric disc valve technology

Manufactured on computerised SPMs, the perfect concentricity and flatness provides close tolerance and ensures a aerodynamic flow for low resistance. All of which means higher reliability, least valve losses & power savings.

Light weight piston & teflon rings

Special design light weight piston result in lesser inertia forces resulting in increased power savings and the ceramic filled teflon piston rings are higher wear resistant and hence have longer life.

One piece bearing suited for near life time operation

Shrunk fit bearings ensure proper alignment & clearance thereby reducing wear and tear. They have very high load bearing capacity. Ideally suited for high pressure piston compressors.

Overhung crank shaft for easy maintenance

Twin sleeve bearing on the crankshaft at the flywheel side to take the weight of the belt wheel. It is very easy to repair at customer site.

Scroll Oil Free compressor

The air is sucked in from the suction mouth at the outside of the fixed scroll. The air enclosed in the compressed space is compressed towards the center when the compression chamber is becoming smaller due to the rotation movement. The compressed space becomes smallest in th e cen ter , an d th e air compr essed to th e hi gh est limit is squeezed out fr om th e cen tr al exhaust port.
