BFA-R EC • Fan casing - 40 mm insulation with EC motor

• 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
  

• 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

• Potentiometer, type ESCP010
• Flexible connection, type BMK

• The centrifugal fan box shall be acoustically insulated with 40 mm rock wool fibrewith a density of minimum 88 kg/m³. The closed motor shall be of the direct driven type, IP44, insulation class B, with thermal protection, voltage controllable with auto transformer
