Blauberg Volute-S

The dual-purpose centrifugal smoke extraction fan is used in emergency exhaust ventilation systems for forced removal of smoke, heated gas and combustion products. The fan may be used for general exhaust ventilation. The fan is a component part and is not designed for independent operation.

The fans are made from steel with heat-resistant polymer coating, which ensures protection from weather conditions. The impeller and backward curved blades are powder-coated. The fan’s casing can rotate within the angle range of 0° – 315°. The unit design is constantly being improved, thus some models may be slightly different from those described in this catalog.

The fans are equipped with three-phase electric motors rated for a voltage of 400 V. The motor is located outside of the transported air flow. The motor protection class according to IEC 60034-5 is IP55.

The fan is designed to remove smoke and air mixtures heated up to +400 °C for up to 120 minutes, and long-term operation with transported air temperature of up to +120 °C. The fans can be equipped with a frequency converter to adjust the rotation speed. The fan may be used for general extract ventilation. The fan can be designed for temperate (U) , tropical (T) or maritime moderately cold (M) climate of the first placement category.
