Heavy hammer fan



Main structure 
Fan is mainly composed of fan blade, motor, outline border, protective screening, support frame, blind window, air collector and other parts. In the motor rotation, the blades are driven to generate airflow to open the blind window, the blind window can automatically open after the startup, the blind window can automatically close after the shutdown to prevent the outdoor dust and foreign matters, etc., and also prevent the influence of rain and snow and downdraft. 


Performance characteristics: 
Outline border is made of advanced automatic numerical control equipment processing technology with high precision; The extra-thick galvanized layer has an extremely strong corrosion resistance. With high strength aluminum alloy die-casting hub, new twisted punch forming fan blade, reasonable blade angle can reach the airflow; 380V three-proofing special motor with high quality and high performance can make the fan efficiency into full play; 8 strict quality test procedures: Noise test, vibration test, airflow test, motor test, dynamic and static balance test, rotary concentric performance test, blade rotate speed test and overall efficiency test The rear safety net of iron air collector, fiberglass air collector, ABS engineering plastic air collector (three options) used is  convenient for assembly and disassemble and is easy to maintain; CAD Optimization design
