Centrifugal fan made of plastic. High-pressure fan for industrial applications, suitable for conveying corrosive and acidic media. Designed for simple and direct installation on a pipework system. Features a low noise level and high efficiency. The motor is located outside the airflow, and the motor base made of epoxy-coated sheet steel for mounting the fan is included in the delivery. The housing is made of plastic with a standard orientation of LG 270°. Suitable for temperature ranges from -15 °C to +70 °C. Centrifugal impellers have backward curved blades made of polypropylene.

The fan is equipped with a three-phase asynchronous motor with a protection class of IP55 and operates in mode S1 (continuous operation). Speed is controllable with a frequency converter, with a permissible frequency range for speed control of 20-50 Hz. The temperature in the fan motor is monitored by PTC thermistors, which must be connected to a tripping system that disconnects the fan from the mains if the temperature is too high.
