Tri-Lobe Roots Blowers/Compressors

Beta provides a complete range of blowers having flow rate ranging from 10m3/hr to 15000 m3/hr for working pressure up to 1kg/cm2(10,000MMWC) in pressure applications and up to 0.5kg/cm2(5000MMWC) in Vacuum applications.

Beta Blowers are available as complete package units or as a bare blower unit for replacement of an existing blower.

Working Principle:

Tri Lobe Blowers/Compressors are positive displacement units, whose pumping capacity is determined by size, operating speed and pressure conditions.

It has two Tri-lobe (each lobe at an angle of 120ᴼ) impellers mounted on parallel shafts, rotating in opposite directions within a casing closed at the ends by side plates. Impellers rotation allows air 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.

Advantages of Tri-Lobe Blower over Twin-Lobe Blower:

• In Twin Lobe the lobes are dispersed at 180ᴼ to each other whereas in Tri-Lobe the lobes are at an angle of 120ᴼ to each other which increases resistance to angular deflection in Tri-Lobe Blowers.
• Twin lobe conveys 4 large pockets of air from suction to discharge in one revolution whereas Tri lobe conveys 6 small pockets of air due to which pressure pulsations in Tri-Lobe blowers is comparatively less than that of Twin-Lobe blowers which in turn reduces the noise level of Tri-Lobe Blowers.
• Due to presence of Tri-Lobes there is better load distribution between rotors and gear sets which enhances life of both bearings and gears.
• Due to better load distribution in Tri-Lobe design, it is possible to operate Tri-Lobe Blowers at comparatively high speeds of up to 4000RPM which is not possible in Twin-Lobe design.

Features of Beta Make Twin Lobe Roots Blowers:

• Superior product quality & robust design
• 100% oil free air delivery
• Anti Friction bearings are used in every blower
• Precision ground and hardened steel gears are used to ensure smooth, silent running and accurate timing of the rotating impellers.
• Suitable for handling air/gas
• Dynamically balanced rotors as per ISO 1940/1,Gr. 6.3 to ensure vibration free operation
• All machines are thoroughly tested for performance parameters as per BS-1571-Part-2 prior to dispatch
• Improved volumetric efficiency and reduced operating temperature
• Beta blowers have large shaft diameter comparative to many other manufacturers which keeps drive stresses low enabling increased operating pressures to be achieved without increasing blower size.
• Both side oil splash lubrication
