2). Imported bearing, high-strength, low noise and long service life
3). Shutter are made of high strength hot-galvanized steel sheet, anti-tioxidant, light weight and no distortions
4). High strength dabber aluminum-magnesium alloy wheel. High strength and long service life
5). Mirror designed and injection moulding Stainless steel blade, with big air volume, never distortion and
Broken
6). High efficient and energy-saving motor with CCC certificate, protection class: IP55, insulation class: F grade
7). The cone part, designed as a horn, maintenance-free. Do not need to replace the belt for maintenance.
8). The design of shuter system adopt the principle of air forward flow, preventing rain water entering the room. Do not need electricity or manual switch for opening and closing.
Priciple of negative pressure fan: The negative pressure fan is designed according to the air convection and the principle of the negative pressure ventilation. The negative pressure fan is usually installed in poor ventilation places. When it is working, it will force out the stagnant hot-gas, peculiar smell and squalid smoke bythe negative pressure rapidly in the shortest posssible time. At the same time, fresh air will be supplied into the door quickly and flow circularly, so as to achieve the aim of ventilation and cooling and improve the workshop's environment.
