Application
The RE/REC Series of direct drive centrifugal fans provide an excellent solution for residential or commercial ventilation applications where the fan must be mounted on the exterior of the building. These multi-purpose fans can be used to move air from one or more venting points. Interior noise is not an issuebecause the fan motor is located outside the building envelope. 
 
Design
The motorized impeller is both statically and dynamically balanced as one integral unit, for vibration free, quiet performance. Motor bearings are a permanently sealed, self-lubricating ball type. 
 
Motor protection
Built-in thermal overload protection with automatic reset.
