Vacuum blower

RSV vacuum fan is a kind of positive displacement fan. Its negative pressure can be adjusted within the allowable range according to user requirements. There are two sets of impellers rotating in opposite directions inside the chassis, which rotate in a state where there is only a very small gap between the impeller and the impeller, and the impeller and the housing.When the impeller passes through the suction end, a certain amount of air is captured between it and the housing. With the rotation of the impeller, the air moves sideways and is discharged from the outlet end.During operation, the negative pressure of the suction end pipeline will slowly increase until the required value.

Technical features

The air volume and pressure range are large.
Caliber: 40-300mm
Air volume: 0.8-179.2m³/min
Vacuum pressure: -1000mmAq ~ -6000mmAq

Computer dynamic balance correction, low vibration and low noise.

The air volume is stable, and the pressure change has little effect on the air volume.

Special impeller design, high efficiency and energy saving.

The structure is simple and sturdy, and trouble-free.

The use of first-class grinding gears has high accuracy, long life and low noise.

Strict quality management, standardized products.

The impeller adopts the latest six-axis machining method of Longmen planer, which is completed in one machining, which makes it easy to replace and has higher precision.
