Coupling Drive Centrifugal Fans
The No.7 Arrangement, also known as the Coupling Arrangement, is designed for SINGLE INLET CENTRIFUGAL fan sets.
Centrigual Fans
Distinct advantage over direct drive systems
Introducing our No.7 arrangements, a versatile option in our lineup. Similar to the No.4 Pedestal design, the No.7 features a motor placed on a pedestal, aligned directly with the impeller hub. However, in the No.7, a shaft and bearing unit, connected via a flexible coupling, separate the motor from the impeller hub. This configuration is often used instead of a direct-driven fan (No.4) in situations where the fan and motor's physical size make future maintenance a key consideration. With the No.7 arrangement, the fan and impeller can be removed independently of each other, simplifying future maintenance tasks.
