BKKF SQUARE DUCT FANS BACKWARD CURVED

 The double-skin panels with heat and sound insulation are manufactured from galvanized sheet metal. The fans are made of high-quality galvanized steel which is resistant to corrosion. All models have an external rotor motor with closed structure. The device is capable of handling air at max. 40ºC.

The fan blades are aerodynamically curved and provide regular flow. The fans are composed of backward sloping and infrequently arranged fins.

The swing-out lid allows the product to be maintained effortlessly without removing the fan. They work quietly thanks to isolation. Thanks to the removable panels, the air can be easily steered in the desired way. Speed can be adjusted with speed control devices.

Optional control devices can be provided.Speed control can be done with linear voltage regulator in 1 ~ phase products (see BSC accessory). Speed control with frequency inverter can be done in 3 ~ phase products (see BSC-F accessory)

It is designed to meet medium and high volume ventilation requirements in channel systems where the application area is limited.
