Single Suction 2-Stage Centrifugal Fan
MODEL FT2B
For Oil & Gas, Petrochemical Plants, etc.
Product Outline
DMW’s single suction 2-stage centrifugal fans are designed and manufactured based on the following concepts.
High Efficiency
CFD analysis is used to design the impeller and the passage to improve efficiency and reduce shaft power.
High Reliability
The fan consists of well-proven components manufactured with our advanced processing technology.
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 and inspection easier.
