Systemair RVF 100 EC Wall fan - Centrifugal wall fan, <125W

• EC-motor with high efficiency throughout the entire fan performance range • Less energy use, resulting in lower energy costs • 100% speed controllable • Pre-wired potentiometer (0-10V) that allows you to easily find the desired working point. • Ventilation on demand - easy to adjust ventilation rate to actual need • Low sound level throughout the entire fan performance range • Integrated motor protection • For mounting on external walls • Useful where internal space is limited 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. All ambient noise created by the fan is kept outside the building if it is installed on an external wall. EC EC technology is intelligent technology; using integral electronic control which eliminates the slip losses in the motor and ensures that the motor always runs at optimal load and guarantees that the proportion of energy ...
