? Features:
1. The pressure changes with the change of system resistance and is adaptive.
2. It has the hard exhaust characteristic of forced air supply, that is, when the pressure changes, the flow changes little.
3. The transmission medium does not contain oil.
4. The flow is classified and dense, covering a wide range, which can be widely used by users.
5. Various sealing forms can meet the needs of different media.
6. There are many specifications and varieties, including vertical, horizontal, positive pressure and negative pressure.
7. Advanced structure, reliable operation, long service life, convenient operation and maintenance.
? Purpose:
The conveying medium includes clean air, clean gas, sulfur dioxide and other gases. It is widely used in power, petroleum, chemical, fertilizer, steel, smelting, oxygen production, cement, food, textile, paper making, dust removal and blowback, aquaculture, sewage treatment, pneumatic transmission and other sectors.

What are the advantages of three blade roots blower?
1. Large displacement:
Under the condition of the same center distance and outer circle radius, the displacement of three blade rotor Roots blower with circular blade is larger than that of two blades.
2. Low noise:
The vibration and noise of the rotor of the three blade roots blower is smaller than that of the two blade blower, and the life of the bearing used on the three blade rotor is about 15% longer than that used on the two blade blower.
Moreover, the three blade rotor can use twisted blade rotor to reduce its noise and vibration, and the two blade rotor cannot use twisted blade structure due to structural limitations 3. The structure is more stable
The mechanical performance of the three blade rotor is better. Compared with the two blade rotor, the clearance between the impellers and between the impeller and the casing can be better guaranteed. The rotors of three blade roots blowers, especially the twisted blades, are more and more used in automobile supercharging due to their good noise and dynamic balance performance.
? Summary:
The two blade roots fan is less used now, because the three blade fan uses two impellers for three times of suction and exhaust every time it rotates. Compared with the two blade fan, the gas pulse is smaller, the load is smaller, the mechanical strength is high, the noise is low, and the vibration is small. Three blade roots blower is generally recommended.
