BACKWARD CURVED FANS
Fan Components and Material Properties
The fan is made of high quality galvanized steel which is resistant to corrosion. Some models can also be manufactured in plastic or aluminum to meet application and perform a nee requirements. All fans have an external rotor motor that creates a compact structure and have air transport at max. 40°C. Motors are mounted to the fan by means of tight fitting or fasteners. Thanks to the holes on the motor cover, it can be mounted easily on the surface. The suction flange is available as an option.
Fan Structure
The fan blades are aerodynamically curved and provide regular flow. The fans are composed of backward sloping and infrequently arranged fins.
Benefits
The rotation of the fan on the motor housing saves efficiency and space. It works at optimum sound levels while providing strong air suction. It can be operated in any position. Speed can be adjusted with speed control devices.
Speed Control
Optional control devices can be provided.
1~ phase products can be controlled with linear voltage regulator (see BSC accessory). Speed control can be done with frequency inverter in 3~ phase products
Usage Areas
They are used in air-conditioning devices and duct fans.
