Single Suction Multi Stage Centrifugal Blower
MODEL BTnP
For Oil & Gas, Petrochemical Plants, etc.
Product Outline
DMW’s single suction multi-stage centrifugal blowers are designed and manufactured based on the following concepts.
High Reliability
The blower consists of high precision components manufactured and processed with our extensive know-how and is assembled by experienced technicians.
High Efficiency
CFD analysis is used to design the impeller and the passage to improve efficiency and reduce shaft power.
Quiet Operation
Rotor imbalance is corrected with a dynamic balancer to suppress vibration during operation.
This enables stable continuous operation for a long period.
Easy Maintenance
The horizontally split structure of the casing makes maintenance easier.
