Overview for Fantech REC10XL Fantech's RE / REC Series 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. Two base styles are available: RE models with a flat base for direct flashing to the roof or REC models with flanged base for curb mounting. RE models can also be mounted on an exterior wall when roof access is not suitable. With duct diameters from 4 to 10 inches, air performance from 116 to 1008 CFM, and 100% speed controllability, these multi-purpose fans can be used to move air from one or more venting points. Interior noise is not an issue because the fan motor is located outside the building envelope.
