Exhaust Fans

Performance

• Drop hammer fan mainly consists of blade/motor/frame/ protect net/bracing cage/shutters. The motor drives blade to cause flow and louver window can open and close automatically to keep the dust from entering.
• Frame using advanced automatic processing, height precision; extra-depth zinc coating frame, high corrosion resistance.
• High-strength aluminium alloy casting pulley, and reasonable perspective blade, to reach the maximum airflow.
• High-precision micro-computer-aided manufacturing system make the best efficiency of the fan.
• Five strict quality testing procedures: noise detection, vibration testing, concentric rotation performance testing, the speed of blade testing and whole fan efficiency detection
• High quality motor with CCC certificate, IP55, Class F grade. Use galvanise, FPR and ABS wind collector. Protect net is easy to be disassembled. CAD/CAM optimising design

Performance

• Special push-pull shutter mechanism can open and close shutter automatically.
• Stainless steel blade adopted one punch forming technology.
• Big airflow, no broken, no dust and attractive and durable.
• Unique concave handling design of exhaust fan not only helps avoid inconvenience occurred in the transport but also keep favorable installation and beautiful exterior.
• V-belt is made of high-strength and light-weight aluminium magnesium alloy, formed by heat press processing.
• Installed efficient and energy-saving motor with CCC certification. Protection level: IP55. Insulation F grade.
• Adopted high-quality nylon PA66 to ensure the long service life. The fasteners of a centrifugal system all are copper rivets, wear-resisting and no rust, flexible. A guide rod is made of 304 stainless steel, ensure the high strength, no rust, and reduce friction.
