The FT30C Fiberglass Motor External Axial Flow Fan features a rational structure, simple design, high static pressure, high efficiency, excellent corrosion resistance, low noise, smooth operation, minimal mechanical vibration, and smooth airflow. The motor is mounted on the upper portion of the fan body and utilizes an adjustable motor support plate and an angled toothed belt drive to isolate the various corrosion-resistant gases conveyed by the fan from the motor, thereby ensuring the motor's service life. The fan utilizes an external groove spherical universal bearing seat, offering advantages such as compact size and excellent sealing performance. This series of fans is primarily suitable for series pressurization and air supply and exhaust in general industrial pipelines. The conveyed gas must not contain viscous materials, dust, or hard particles. The gas temperature must be ≤60°C and the relative humidity ≤100%.
