You will find all Exhaust fans with frequency-controlled motor and linear air stream from Ruck® here! With these fans, the air stream continues in the same direction with respect to the duct. These Exhaust fans are suitable for extraction in catering establishments because the motor is mounted outside the air stream and can therefore extract air of high temperatures. The fan is available in many different capacities, from 1960 m³/h up to 12075 m³/h. Attention: these Exhaust fans must be controlled with a frequency converter. They are available separately.
