+86-13963692323Performance characteristics：
1. The galvanized sheet of extremely thick zinc coating guarantees the high strength of fan frame and the high corrosion resistance.
2. V-shaped belt pulley is modeled by the hot pressure casting of high-strength aluminum magnesium alloy materials. It is light in texture and high in strength. The belt adopts the automatic tension expanding device so that the belt doesn't loosen and fall.
3. It is configured with the energy-saving motor and passes the certification of 3C with the protection grade: IP55, insulation grade: Level F
4. Mechanical centrifugal open institutions are molded and processed with raw materials of high-toughness reinforced nylon with high strength and long service life.
5. It adopts the iron air collector and the glass steel air collector. The rear installation net is convenient for disassembly, with the optimization and design of CAD.
6. The high-precision microcomputer assists the production system, and has the following strict quality detections: noise detection, vibration detection, blade, rotation speed detection and the effect performance detection of complete machine. The fan has stable operation without vibration, which reduces the noise and effectively improves the service life. 。
