fan for wooden boiler

The fan is designed for air supply in central heating boilers with a power of 25–50 kW, and is also used in other technological devices with an ambient temperature of -15°C to +40°C and a relative humidity of up to 95%.
The fan housing is made of aluminum alloy. The external rotor motor is mounted inside the housing and attached with M4 screws. The metal fan rotor is placed directly on the outer rotor of the motor. The opening through which air enters the fan is protected by a cover that prevents fingers from touching the moving parts of the fan/turbine. All electrical connections are placed in a junction box made of insulating material.
The fan motor is adapted for speed control. The fan has an EU conformity certificate.
