Sound insulated duct fan (40 mm insulation), centrifugal fan with EC motor
Application
BFA-R EC fans are used for ventilation in many applications where low noise levels have to be respected, such as offices, restaurants, technical rooms or other
The BFA-R EC can be controlled by an external analogue signal (0-10 V): ideal for realising a control in function of CO2, temperature, constant pressure or humidity
Can be used for air supply or extraction
Indoor and outdoor installation possible without additional accessories
Composition
Casing procured from galvanised steel
Removable panel with mounted roof, fixed with screws for easy inspection of motor
Isolation: high performance wool (88 kg/m³) with fireclass A1 according to DIN EN13501-1
Fan with backwards curved blades
Only suction fan, completely synthetic
Isolation class motor B for diameter 355 and 400, class F for all other diameters
Protection classes:
BFA-R 125 - 200 EC K 01 et BFA-R 355 - 500 EC K 01: IP54 for the motor protection class and the whole fan
BFA-R 250 - 315 EC K 01: motor protection class IP33, IP54 for the whole fan
BFA-R 450 - 500 EC K 01: motor protection class IP55, IP54 for the whole fan
Terminal box IP66 with cable glands
