1. An Overview of Dual Inlet Forward Centrifugal Blowers
(1)Description
Dual Inlet Forward Centrifugal Blowers are designed for use where space limitations are a problem. The impellers are permanently mounted to the external rotors for ease of installation and maintenance-free operation. These units may be mounted in any orientation for effective air movement. Optional configuration includes different size scroll housing and impellers mounted on either end of the motor, airflow aimed at any angle and various output characteristics.
