DIRECT DRIVE RECTANGULAR IN LINE DUCT FANS/BACKWARD CURVED

Fan Components and Material Properties
Rectangular body is manufactured from galvanized steel sheet. The fans of the BDKF-R 315-355-400 are made of high quality galvanized steel which is resistant to corrosion. The fans of the BDKF-R 450- 500-560 models are made of aluminum sheet. All models use an asynchronous motor and the motor is out of airflow. The device is capable of carrying air at max. 120ºC.
Fan Structure
It is designed to work between the rectangular channel. The fan blades are aerodynamically curved and provide regular flow. The fans are composed of backward sloping and infrequently arranged fins. 
Benefits
Since the motor is out of airflow, it is resistant to high temperature. The swing-out lid allows the product to be maintained effortlessly without removing the fan. Thanks to the aerodynamic wing structure, they work quietly. Speed can be adjusted with speed control devices.
Speed Control 
Optional control devices can be provided. Speed control with frequency inverter can be done in 3 ~ phase products.
Usage Areas
It is designed to meet medium and high volume ventilation requirements in rectangular duct systems where the application area is limited. It is able to carry air at higher temperatures due to the motor being out of airflow.
