Working Principle
The three-leaf Roots blower is a type of volumetric fan. Its pressure can be adjusted within the allowable range according to the requirements of the user. Two sets of impellers rotate only with a very small gap remains bot between the impellers and between impellers and housing. As the impeller rotates the air moves sideways, the pressure gradually rises and then is sent to the outlet end.
- Capacity, Pressure and Vacuum range; Outlet: 40mm-300mm(1.5 “-12”); Capacity: 0.6-160m3/min(21-5700CFM);
- Pressure: One-Stage GRB type 8000mmAq(0.8kgf/cm2).
- Delivers completely oil-free air.
- Low oscillation and low noise by complete balancing.
- Small change in capacity against change in pressure
- High efficiency due to special profile. Simple structure, free from trouble.
- Highest quality pilot & Accurate great applied,
- long life and low noise assured.
- Standardized product with strict quality control.
- Our rotor has used the most advanced-one time for all working process of the Four-
