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. The motor base, made of epoxy-coated sheet steel for mounting the fan, is included in the scope of delivery. The housing is made of plastic with a standard orientation of LG 270°. Suitable for temperature ranges from -15 °C to +70 °C. The centrifugal impellers have backward curved blades made of polypropylene.

It is equipped with a three-phase asynchronous motor with a protection class of IP55. The operating mode is 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 permanently disconnects the fan from the mains if the temperature exceeds safe limits.

Electrical connection is made in the terminal box on the motor. The flow rate is 2250 m³/h, with a speed of 1440 rpm. The impeller type is radial, and it is not reversible. The fan operates on three-phase current with a rated voltage of 400 V and a mains frequency of 50 Hz. The rated power is 250 W, with a current of 0.85 A. The protection rating is IP 55, and the thermal class is F. The fan does not have pole-changing capabilities.

Installation location is for pipe connection, and the installation position is horizontal. The housing material is plastic (polyethylene), and the impeller material is also plastic (polyethylene). The color is light grey, with a weight of 45 kg and a weight with packaging of 68 kg. Dimensions are as follows: size 310 mm, width 527 mm, height 640 mm, depth 560 mm; with packaging: width 1200 mm, height 800 mm, depth 790 mm. The fluid temperature at maximum is -15 °C to 70 °C.
