Reliable operation: The main components are processed by CNC equipment with high precision; There is a gap of 0.2-0.5mm between the rotor and the transfer, as well as between the rotor and the housing, without friction, allowing the airflow to contain a certain amount of dust, reducing the probability of faults and ensuring good operational stability.

Product Features
Structural design: Composed of two Roots blowers connected in series, each blower housing has two three bladed rotors with opposite directions inside. Each three bladed rotor is supported by two bearings and a pair of high-precision synchronous spur gears are used to maintain the relative position of the two rotors. A certain gap is maintained between the rotors and between the rotors and the housing, allowing for non-contact rotation and reducing friction and wear.
Stable performance: The two-stage three blade Roots blower has high volumetric efficiency, large air supply, stable operation, reliable use, and relatively stable working characteristics. Within a certain pressure range, its flow rate changes little with pressure, which can force gas transmission and ensure stable output gas flow rate to meet the system's requirements.

Function
Gas pressurization and transportation: By connecting two Roots blowers in series, the gas is pressurized twice, which can transport the gas to a higher pressure to meet some process requirements with high gas pressure requirements. For example, in pneumatic conveying systems, when materials need to be transported to distant or higher positions, sufficient pressure is provided to overcome pipeline resistance and material gravity.
Stable gas supply: With the characteristic of forced gas transmission, it can maintain a relatively stable gas flow output under different pressure conditions, ensuring the stability requirements for gas supply in the production process.

Compared to single-stage Roots blowers, two-stage series Roots blowers may consume less energy under the same pressure and flow requirements.
High reliability: The service life of each bearing is uniform, and the fan oil seal is made of imported fluororubber material, which is resistant to high temperature and wear, resulting in a long service life and high reliability of the fan. At the same time, its stable working characteristics and fewer fault points reduce production interruptions caused by equipment failures, lowering maintenance costs and production losses.
