BKF 315D4-6-XL/F400 Smoke extract centrifugal fan, 120°C continuous, 400°C/2 hours, 2,632m³/h
BKF smoke and heat extract fans are used in case of fire to extract smoke gases and also during normal working conditions for standard ventilation. Smoke free escape routes assist egress and provide clear access points for fire departments. Extracting poisonous and hot gases also make fire extinguishing easier and reduce the damage on the building. For speed control of single speed motors use combination of frequency converter and appropriateFilter to motor side (sine or du/dt), respectively observe
Smoke free escape routes assist egress and provide clear access points for fire departments. Extracting poisonous and hot gases also make fire extinguishing easier and reduce the damage on the building.
Applications: malls, garages, 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 combination of frequency converter and appropriateFilter to motor side (sine or du/dt), respectively observe instructions. Not suitable for voltage control. Working points within blue area of diagrams of single speed fans can be achieved with frequency converter. Tested to 400°C/2h together with frequency converter. However, we recommend bridging of frequency converter in case of fire to eliminate possible risk of malfunction of frequency converter. In case of fire all motor protective devices and thermal protections in frequency converter must be bridged or disabled to guarantee functional capability. When choosing AES control accessory please observe serial connecting capability of the motor (instructions).
