Shanti Tri Lobe Blowers

Home - Shanti Tri Lobe Blowers

SHANTI Blowers Commenced Manufacturing of Positive Displacement Blowers way back in 2008 . Shanti Blowers manufacturers Tri Lobe blowers starting from 10m3/hr to 7,000m3/hr with pressure range upto 8,000 mmwc

Tri Lobe Blowers have Lobe Tips exposed to 120 Deg instead of 180 Deg as in Twin Lobe Blowers. This provides a stiffer rotor set, which means less deflection at any load. These have been designed specially keeping the specific demands of industry like continuous operation, reduced pulsation and vibrations, Longer bearing life and less maintenance.

Working Principle

Shanti Tri Lobe Blowers employes two tri lobe impellers mounted on parallel shafts, rotating in opposite direction within a casing closed at the ends by side plates. As the impellers rotate, air is drawn into one side of the casing and forced out of the opposite side against the existing pressures. The differential pressure developed, therefore, depends upon the resistance of the connected system. The Blowers, being positive  displacement type, do not develop pressure within the casing but the discharge pressure depends upon the system resistance / back pressure. Effective sealing of the compressor inlet area from the discharge area is accomplished by use of very small operational clearance, eliminating the need of any internal lubrication of the lobes .A pair of accurately machined alloy steel, hardened and ground timing gears maintain clearances between the impellers, during rotation. The air, thus delivered, is 100% OIL FREE. The pumping capacity of a lobe compressor, operating at constant speed remains relatively independent of inlet and discharge pressure variations. These Blowers are constant volume machines, which deliver a fixed discharge against the system back pressure
