BKF-120BKF 710D4-XL-120°C
BKF-120 Rectangular Duct Fans
BKF-120 fans are used for ventilation in normal working conditions and can transport hot gases up to 120°C.
Continuous operation up to 120°C medium temperature
Casing made of zinc-magnesium coated steel (ZM)
Backward curved impeller made from steel and galvanized
Motor outside the air stream
Single speed IE3 motor
PTC serial built-in motor
Installation possible in all positions, flange connection 30 mm
Installation outside building or inside the building
Applications: malls, warehouses, kitchen exhaust...Generally suitable for ambient temperature -20 to +40°C (depending on specific motor load the permissible ambient temperature may be increased - on request). For speed control of single speed motors use a combination of frequency converter and appropriate filter to the motor side (sine or du/dt), respectively observe instructions. Not suitable for voltage control. Working points within the blue area of diagrams of single speed fans can be achieved with a frequency converter.
