Outstanding features and Benefits

Three lobe rotor design

Leads to lower range of pressure pulsations at discharge which results in smoother air discharge, Low levels of noise < 90-100 dbA, vibration less than 80 Microns and Lower shock loading of bearings and timing gears.

Heat-treated castings of graded cast irons

Improves grain structure which ensures dimensional stability, results in higher reliability and lower maintenance.

Dynamically balanced rotors

Lower to noise, vibration levels and reduced bearing loads. Results in smoother operation, low maintenance, higher reliability.

Alloy steel hardened, ground and crowned timing gears

Leads to lower gear running noise, low wear & longer life of gears.

High quality, amply designed anti-friction bearings

Long life of bearings- virtually maintenance free and smooth operation.

Intermediate chamber side covers and labyrinth shaft seal

Prevent oil leakage into main chamber and ensure 100% oil free air.

Optimum internal clearances

Reduce air slippage giving high volumetric and energy efficiency and lower air discharge temperature (generally less than 100 Deg C.).

Bottom Horizontal discharge design with lube oil cooling facility

Compact installation, maintains low lube oil temperature which minimizes wear of gears and bearings.

Engineered, high quality accessories

Reliable, trouble free operation with guaranteed performance.
