Centrifugal fan made of plastic. High-pressure fan for industrial applications. Suitable for conveying corrosive and acidic media. For simple and direct installation on a pipework system. Low noise level and high efficiency. The motor is located outside the air flow. The motor base made of epoxy-coated sheet steel for mounting the fan is included in the scope of delivery. Housing made of plastic. Standard orientation for housing LG 270°. Suitable for temperature ranges from -15 °C to +70 °C. Centrifugal impellers with backward curved blades made of polypropylene. AC motor: Single-phase AC motors. Protection class IP55. Operating mode S1 (continuous operation). The temperature in the fan motor is monitored by PTC thermistors. The PTC thermistors must be connected to a tripping system that permanently disconnects the fan from the mains if the temperature is too high.
