Maico Centrifugal blower 4 pole

Centrifugal fan made of plastic. This high-pressure fan is designed for industrial applications and is suitable for conveying corrosive and acidic media. It is designed for simple and direct installation on a pipework system. The fan 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 scope of delivery. The housing is made of plastic with a standard orientation of LG 270°. It is suitable for temperature ranges from -15 °C to +70 °C. The centrifugal impellers have backward curved blades made of polypropylene.

The fan is equipped with a three-phase asynchronous motor with protection class IP55 and an IE3 rating. It operates in mode S1 (continuous operation). The 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 is too high.

Electrical connection is made in the terminal box on the motor. The flow rate is 12500 m³/h, speed is 1440 1/min, and the impeller type is radial. The fan is not reversible. The voltage type is three-phase with a rated voltage of 400 V and a mains frequency of 50 Hz. The rated power is 4000 W, with an INenn of 8.1 A. The protection rating is IP 55, and the thermal class is F. The fan is not pole-changing and is designed for pipe connection with a horizontal installation position.

The housing material is plastic (polyethylene), and the impeller is also made of plastic (polyethylene). The color is light grey. The weight is 120 kg, and the weight with packaging is 143 kg. The dimensions are 560 mm in size, 760 mm in width, 1045 mm in height, and 930 mm in depth. The width with packaging is 800 mm, height with packaging is 1200 mm, and depth with packaging is 930 mm. The fluid temperature at IMax is -15 °C to 70 °C. PTC DIN 44081: M 100.
