HGF4-72 Type (Type A) Fiberglass Centrifugal Ventilation Fan
HGF4-72 Type (Type A) Fiberglass Centrifugal Ventilation Fan
| Parameter
The HGF4-72 series of FRP centrifugal fans is a high-efficiency, high-performance, and energy-saving environmentally friendly fan designed and improved by our company based on the original 4-72 model. This new model features an optimized design that enhances gas flow performance, with dimensions perfectly tailored to seamlessly integrate with standard ductwork systems. The HGF4-72 series FRP centrifugal fans are engineered and manufactured using advanced vinyl resin composites, drawing inspiration from the performance specifications of the traditional metal 4-72 fans. These fans are specifically designed to handle corrosive gases containing acidic, alkaline, or chemically aggressive components—provided that the conveyed gases remain free of sticky substances, dust, or hard particles exceeding 150 mg/m³. Additionally, the operating temperature must not exceed 80°C, and the relative humidity should stay below 100%. Key advantages of this fan series include exceptional strength, lightweight construction, excellent resistance to aging, superior corrosion protection, low noise levels, and smooth, stable operation. As a result, these fans stand out as highly efficient, high-performance, and energy-saving general-purpose anti-corrosion models. Widely used in industries such as chemical processing, power generation, electroplating, power plants, laboratories, printed circuit board manufacturing, and environmental protection equipment, these fans are ideal for environments where corrosive gases are present.
