Roots Type Rotary Twin Lobe Air Blower

Product Categories

Blowers & Accessories

Product Profile

Air Blower is based on tried & tested volumetric principle by which the volume generated proportional to the speed of rotation, providing a guaranteed 100 % oil -free air and a transported gas that is free of any contamination. This consist of two identical twin or tri lobes that rotate in opposite directions.

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.

Applications

Effluent/water treatment plant
Air agitation of chemical solution
Filter bed agitation
Sulphation process-sugar plants
Cement blending, aeration & fluidation
Pneumatic conveying- cement chemicals
Fertilizer & chemical plants
Pressuration of high altitude chambers
Air blowing glass industry
Agitation of liquids-electroplating plants, ice plants, lamps & luminaries manufacturing plants, etc
Centralised vacuum cleaning
Boosting or evacuation of gases
Fisheries/ hatcheries / aquaculture

Features

Well suited for V-belt as well as direct coupled drive
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
