 Operating Principle:
The blower is of displacement type, and sends a fixed amount of air in proportion to its rotation speed. With the three-lobed rotors, the two rotors make three intake and exhaust cycles per revolution. Because the air has less pulse compared with the two-lobed type, fluctuations in load, noise and vibration are small. While the two three-lobed rotors mounted on two parallel shafts maintain only a very small clearance between themselves and the inner surfaces of the oval casing operation chamber and between each other, they are driven by timing gears, moving a fixed volume of the air enclosed by the casing and rotors from the intake side to the output side. The blower is free of Internal lubrication. And its simple design, easy handling, and stable performance make a wide range of applications possible. 

 Features of 3-lobe Roots Blower: 
● The three-lobe design and reasonable inlet and outlet structure offers a lower noise and small vibration.
● The rotor and shaft have been combined as a single unit with no wear, the performance of the blower is stalbe, permitting long-term continuous operation.
● Large useful cubage, high volume efficiency speed, compact structure and variable installation
● The bearings of reasonable type with average durability prolong blower’s life. 
● The oil seals made of imported fluorubber offers excellent heat-resistance, wear-restistance and long using life.
● The blowers are of various types possible for different applications.
