1. Corrosion resistance
The surface of the galvanized sheet metal negative pressure fan is covered with a dense zinc layer, which resists the erosion of water vapor, acidic and alkaline gases to the machine through the dual mechanisms of physical isolation and electrochemical protection. Ordinary steel plate fans are prone to oxidation and rust, and have a short service life. The zinc layer has high hardness and strong wear resistance, and is not easy to wear in a dusty environment for a long time. The casing of an ordinary fan is prone to corrosion, resulting in a decrease in structural strength, causing deformation or vibration.
2. Improvement of energy utilization
The galvanized sheet metal fan adopts streamlined fan blades, which reduces wind resistance by 15% and increases air volume by 20%-30% at the same power. The machine is equipped with an efficient copper wire motor with IP55 protection level, and the energy utilization rate is 25% higher than that of ordinary fans. The galvanized sheet metal negative pressure fan adopts a thickened hot-dip galvanized shell, a pure copper motor, a large fan blade, and a high-quality rubber belt. It is reliable in quality and cost-effective. The negative pressure fan adopts a low-power pure copper motor, which can greatly reduce energy consumption and operating costs, and is also energy-saving and environmentally friendly.
3. Adaptability and application range
The product has a temperature range of -30℃ to 85℃ and is suitable for high-temperature workshops, high-humidity environments and dusty places. Ordinary fans are prone to failure in corrosive environments and are limited in applicable scenarios. Galvanized sheet metal negative pressure fans are standardly equipped with overload protection and explosion-proof models to avoid motor burning or rainwater backflow. Ordinary fans have simple safety designs and high failure rates.
