Axial Flow Fan Galvanized Negative Pressure Fan High Air Volume
Galvanized sheet is not introduced in detail. As is well known, its advantage in factory ventilation and cooling equipment is its high cost-effectiveness.
Profile negative pressure fan: currently rarely used in the market;
Fiberglass negative pressure fan: Fiberglass is a chemical fiber reinforced plastic.
The characteristics of fiberglass are: (1) light weight and high strength. (2) Good corrosion resistance. It has good tolerance to air, water, acids, alkalis, general concentrations of salts, various raw oils, and organic solvents. (3) Good electrical performance. A good insulation layer material used for manufacturing conductors and insulators. It can still maintain good dielectric charge at high frequencies. Excellent microwave heating permeability. (4) Excellent thermal characteristics. Fiberglass has a low thermal conductivity and is not easily deformed. Due to the strict ventilation and cooling conditions in the workshop, it can be baked with fire.

Introduction to Negative Pressure Fans
Negative pressure fans are the latest type of ventilation fans and belong to the category of axial flow fans. They are primarily used in negative pressure ventilation and cooling projects, addressing both ventilation and cooling needs simultaneously. These fans are also utilized in various applications such as positive pressure water curtain eco-friendly air conditioning, positive pressure air supply, and positive pressure blowing.
Features
Negative pressure fans are characterized by their large size, oversized air ducts, large fan diameters, high air volume, low energy consumption, low speed, and low noise. They are mainly classified into two types based on construction materials:
Galvanized Sheet Square Negative Pressure Fans
Fiberglass Horn Negative Pressure Fans
Most galvanized sheet square negative pressure fans share similar structures and technical parameters. The classification of negative pressure fan models will be detailed further. The fiberglass horn negative pressure fans can be divided into belt-driven and direct drive types based on their transmission methods.
Product Characteristics
The entire unit is designed using CAD/CAM technology, featuring low investment costs, high air volume, low noise, minimal energy consumption, stable operation, long lifespan, and high efficiency. The automatic louvers provide dust and water protection while enhancing aesthetics. These fans can both blow air and extract air, making them the optimal choice for modern workshop cooling and ventilation.
Environmentally friendly and energy-efficient, negative pressure fans are set to become the mainstream choice in the ventilation and cooling equipment market.
