How effective is the galvanized iron shell of the negative pressure fan in dust and pollution prevention?

1. Dust-proof effect
Strong anti-corrosion performance: Galvanized iron has extremely strong anti-corrosion performance. This is because the chemical properties of zinc are relatively active and it is easy to react with oxygen in the air to form a dense zinc oxide film. This film can effectively prevent moisture and oxygen in the air from directly contacting the iron sheet, thereby slowing down the corrosion rate of the iron sheet. This feature enables the shell of the galvanized iron negative pressure fan to effectively resist the erosion of dust, materials and other impurities in the workshop, keeping the inside of the fan clean and operating normally.
Fully enclosed design: The shell of the galvanized iron negative pressure fan usually adopts a fully enclosed design, which can effectively prevent dust, materials and other impurities in the workshop from invading the inside of the fan. By reducing the intrusion of external impurities, the maintenance cost of the fan and the failure rate during use can be significantly reduced.
2. Anti-fouling effect
Easy to clean: The surface of the galvanized iron sheet is smooth and has a certain degree of anti-adhesion, which makes it difficult for pollutants such as dust to deposit and adhere on its surface. Even if there are certain pollutants attached to the surface, they can be easily removed by simple cleaning, thus keeping the fan housing clean and beautiful.
Anti-pollution: The housing of the galvanized metal sheet negative pressure fan has been professionally painted, which not only increases its appearance but also improves its anti-pollution. The coating layer can form a protective layer to further block the direct contact between pollutants and the iron sheet, keeping the fan clean and durable.
