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.
