Drop hammer fan mainly consists of blade/motor/frame/ protect net/bracing cage/shutters. The motor drives the blade to cause flow and the 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, and high corrosion resistance.High-strength aluminum alloy casting pulley, and reasonable perspective blade, to reach the maximum airflow.
High-precision micro-computer-aided manufacturing systems 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 IP55, Class F grade. Use galvanize, FPR, and ABS wind collectors. Protect net is easy to be disassembled. CAD/CAM optimizing design
