Forward Curved Centrifugal Fan for AHU – Wheel Type T – YFFCDT

Impeller Technology

• The forward inclined DWDI impeller has good ability of low noise and reliable running.
• The forward curved impeller has bigger volume comparing with backward curved impeller in the same speed.
• The forward curved impeller has lower speed and lower noise comparing with backward curved impeller in the same working condition.
• Spinning precisely matched Venturi inlets and impeller cones assuring smooth, which further results well rectification effect and low noise.

 

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.

2. Improved Design

• The forward 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.
