Performance features:

  The outer frame adopts the advanced automatic processing technology, and the extra thick hot-dip galvanizing layer has strong corrosion resistance;

  High strength aluminum alloy casting hub, new type of twisted stamping fan blade; reasonable blade angle, can achieve the maximum air flow;

  The high-precision microcomputer aided manufacturing system can make the fan play the maximum efficiency; eight strict quality detection procedures; noise detection, vibration detection, static balance, dynamic balance, rotation concentric performance detection, blade speed detection, overall efficiency detection;

  Adopt iron air collector, FRP air collector, ABS engineering plastic air collector (three kinds), easy to disassemble the rear safety net; CAD Optimization Design;

  The belt automatic tension device is adopted to make the belt not loose, fall off and reduce the failure rate of the fan.
