RANGE From 20m3/hr to 30000 m3/hr with pressure application from 1000mmwc (0.1kg/cm2) to 10000mmwg (1.0kg/cm2) CONSTRUCTIONS CASING : Cast iron in Grade 25 with extra deep rib sections for greater rigidity under vacuum or pressures service. IMPELLERS : are accurately machined in Cast iron or Forged steel for close tolerance & long life operation. Dynamically balanced for smooth running & lower bearing loads. SIDE PLATES : have vents that ensure no risk of oil contamination. BEARINGS : Heavy-duty roller bearings for maximum loading.

Well suited for V-belt as well as direct coupled drives. Material of construction of the casing and lobes for all blowers is C.I.F.G.-260 conforming to IS: 210. Shaft material is alloy steel, EN24 (817M40) conforming to BS: 970 Part-iii Close tolerance between the impellers, body & side plates to minimize Back Slippage of air improving efficiency & reliability Impellers & pulleys are dynamically; balanced to avoid undue load over the bearings. Precision hardened & ground helical gears located for more input torque capability are used to ensure smooth, silent running and accurate timing of the rotating impellers.
