Logo-Energy-Efficient-Blauberg-NA

Inline duct fan for supply and exhaust ventilation and air conditioning systems of various premises requiring cost-saving controllable  ventilation.

The best ventilation solution for exhaust ventilation of bathrooms, kitchens and other humid premises. 

Compatible with Ø 100 up to 315 mm round air ducts. 

Durable, impact-resistant and corrosion-free ABS-plastic casing.

Aerodynamically shaped casing.

Airtight terminal box for connection to power mains.

High-efficient direct current EC motor with external rotor and backward curved blades.

EC technology meets the up-to-date requirements to energy-saving and controllable ventilation and provides up to 35 % energy saving as compared to asynchronous motors.

EC motor ensures totally controllable speed range for the fan and has integrated overheating protection with automatic restart.

EC motor has no friction and wearing parts as capacitor und brushes. Instead a maintenance-free EC controller electronic circuit board is used.

The impeller is dynamically balanced.

The fan is compatible with 50 Hz and 60 Hz power mains and the maximum speed does not depend on power mains frequency. 

 

The fan speed is controlled with a 0–10 V control signal from the following sources:

  • integrated or external speed controller
  • controller with sensors
  • central BMS system.

The control signal value changes depending on air temperature, pressure, smoke concentration and other parameters.

During signal value change the fan with EC motor correspondingly changes the rotations speed and delivers required air volume to the ventilation system.

The computer central building management systems (BMS) enable integration of several EC motors in network and precise individual operation control for each fan.

The fans are designed for duct mounting in any point of the ventilation system with the casing mounted at any angle. In case of vertical mounting a protective outer hood must be installed on the top.

Fixation to the floor wall or ceiling is performed with the supplied mounting brackets.

Electric connection and installation must be performed in compliance with the manual and the wiring diagram on the terminal box.
