Three Lobe Roots Positive Displacement Air Blower With High Precision Impeller
Features:
- HRB is a displacement blower, the pressure can be adjusted according to the requirement of the user in allowing range
- There are some tiny gap between the impeller to body, impeller to impeller which ensures the impeller rotate
- GRB blower has wide range of capacity and pressure, the pressure of one-stage GRB reach to 8000mmAq
- With the break-through of technology and the modification of practical application, HRB series bowers have higher efficiency, higher pressure and lower weight.
- The biggest feature of HRB is high rotation speed( the maximum can be 4000RPM), high capacity.
- The inlet sizes of HRB are from 2.5" to 12", the pressure of single blower can be 1 Kgf/cm²
