RS 40-20 EC sileo Rectangular (400x200mm) duct fan - 1,360m³/h, 230v, 166W.

RS 40-20 EC sileo. The RSI models are thermally and acoustically insulated with 50mm mineral wool and perforated sheet steel on the inner surface. This gives a quiet running with many installation possibilities. The RS/RSI EC series have impellers with backward-curved blades and are fitted to EC external rotor motors. These fans have a high capacity in relation to their compact design. The fans are delivered with a pre-wired potentiometer (0-10V) which allows you to easily find the desired working point. EC fans are notable for their economical use of energy and excellent ease of control. They can be varied in speed to match the airflow demand, and operate at high efficiency levels. For the same air volume, they consume distinctly less energy than AC fan drives. Motor protection is integrated in the electronics of the motor. The casing is manufactured from galvanized sheet steel.
