Featuring a galvanized steel housing, the Fantech RVF4XLEC Centrifugal Exterior Duct Fan is the perfect solution for direct through-wall ventilation where quiet operation is required in residential or commercial applications. RVF fan motors mount to the outside wall of the building limiting noise from operation. This 120 volt model can produce a maximum airflow of up to 254 CFM. The RVF4XLEC is constructed with a 4" round duct.
Permanently Lubricated Sealed Ball Bearings
Permanently lubricated sealed ball bearings extend the service life of your fan.
By having the ability to be installed outdoors, all of the ambient noise is kept outside.
100% Speed Controllable
On-demand ventilation and precision balancing of systems is controllable through voltage reduction. A pre-wired speed control potentiometer is included to control the EC motor for the most efficient solution for your needs.
By being located on an outside wall, you have easy access to the fan. This unit comes with a removable housing for immediate access to the motor and wiring.
High Efficiency Motor
The RVF4XLEC features a high efficiency EC motor that both reduces energy consumption and also provides 100% speed control.
