Features

The main operating component of the fan - the motor - is made of cast iron base and is an outdoor fully enclosed waterproof motor. The rated service life is designed to be over 80,000 hours, and the anti-corrosion grade is IP55. An aluminum alloy casing can also be adopted, which not only reduces the overall weight of the machine but also has excellent corrosion resistance, does not rust, can increase the motor's lifespan and reduce motor noise.The outer cylinder of the fan is formed by one-time rolling, with a gentle curve, elegant appearance and strong practicality.The fan blades are formed by die-pressing high-strength aluminum alloy plates, featuring large air volume, low noise, high efficiency and long service life.The entire fan undergoes hot-dip galvanizing treatment to enhance its anti-corrosion ability, improve the appearance quality and service life of the fan.

Application:Specifically designed for the heat dissipation and cooling systems of large and medium-sized transformers.
