IMPROVED ROOTS WHISPAIR DESIGN :

Whispair Twin Lobe is an improved design over the conventional blower and is introduced for the first time in India by UNIVERSAL.

A special Whispair pocket is provided in “ROOTS” blowers, at the discharge end, integral to the main housing.

The incoming air is trapped by the lobes and moved through the machine, as in the conventional rotary air blowers. As the lobes rotate further the Whispair slot opens allowing a jet of air from discharge pressure line to enter back into the trapped air area zone. This feedback results in Equalization of pressure between the trapped air and the discharge area, thereby reducing load on Lobes and subsequently power saving. The feature improves efficiency, reduces noise level and increases bearing life. These are the major benefits for a customer applying ROOTS blower.

• CEMENT INDUSTRY
• FERTILISER PLANTS
• CHEMICAL PLANTS
• SUGAR FACTORY
• GLASS INDUSTRY
• ICE PLANTS

TYPICAL PERFORMANCE PRESSURE CURVE : Performance pressure curve of a Blower indicates the Speed vs Brake Horse Power characteristics of the blower at the various operation pressure. The intersection of the vertical line drawn at the speed, to the desired pressure line gives the capacity and B.H.P of the blower.

THE LOBE COMPRESSORS ASSEMBLY :

SR. No	PART NAME	DESCRIPTION
1)	Main Body	Made out of close grained C.I Grade 20, with intergri : Whispair” poacket. Single Piece casting for rigidity. Strength and improved heat transfer
2)	Pulley Side Plate (P.S.P)	Made out of close grained C.I Grade 20 and is suitable rided for high rigidity and designed to resist axial and radial vibrations.
3)	Gear Side Plate (G.S.P)	Made out of closed grained C.I Grade 20 and is designed for high rigidity and strength.
4)	Driving Rotor	Involute profule impellers fitted with high tensile & toughened.
5)	Driving Rotor	Alloy Steel shaft. The complete Rotor assembly is dynamically balanced to ISO : 1940 Standard.
6)	Bearings	Both the impeller assemblies are supported by high dynamic capacity antrification bearings making the blower suitable for continuous duty operations.
7)	Gear Side Cover	C.I Gear cover having fins for effective cooling of lubricating oil.
8)	Timing Gears	High Tensile Alloy Steel hob cut, inducation hardened & ground/lapped to ensure high mechanical efficiency.
9)	Seals	High quality oil seals on shafts restrict leakage of oil or grease to the impellers thus ensuring oil free delivery.
