Backward Curved Centrifugal Fan for AHU – Wheel Type H – YFBCDH

Impeller Technology

• The backward curved impeller has higher efficiency comparing with axial wheel, mixed flow impeller and forward curved impeller.
• Accurately sized V-type performance baffle effectively reduced turbulence which results low noise and high efficiency.
• The backward curved impeller has repeatedly optimized performance cures results safer running.

 

General Features

1. Advanced Technology

• The fan housing is “Pittsburgh” method joined, which results zero air leakage.
• The two pieces of housing side joint at the same one-time procedure to improve the accuracy and reduce the dimension of assembly error.
• The blades are made by once punch forming, and dedicated fixture to ensure precise install.

3. Improved Design

• The backward curved impeller precisely designed reinforcing threaded rod make sure long time reliable running.
• The fan is supported by stable channel steel frame, so that stable running of the fan is ensured.
• Statically and dynamically Balance level up to G2.5.
• Reducing the vibration of the fan, to improve reliability.
• Reducing the running noise effectively.
