Here you will find all Ruck® Exhaust fans with frequency-controlled motor, the Ruck® MPS D-series! This motor is mounted outside the air stream so that the fan is also suitable for high temperatures. This makes the MPS fan also suitable for extraction in the catering industry. The Ruck® MPS fans are available in capacities from 1960 m³/h to 7890 m³/h. Attention: the fan must be controlled with a frequency converter.
