The RVF models are exhaust-air fans for installation on external walls. The unit consists of an impeller with backward-curved blades and a casing in galvanized sheet steel with a white powder-paint coating. When installed on an exterior wall, all ambient noise is kept outside.
- Galvanized steel housing features powder-coat finish
- External rotor motor with totally enclosed design allows fans to operate in high moisture, lint and dust laden air
- Permanent split capacitor motors feature automatic reset thermal overload protection and sealed ball bearings for long life and maintenance-free operation
- All motors and impellers are designed as one integral unit, allowing for excellent motor heat dissipation, even at low RPM
- Permanently lubricated sealed ball bearings
