ZR series normal-grade double-shutters wall-mounted evaporative air cooler

1.CAD/CAM optimizing design
2.Five rigorous quality testing procedures
3.Extra-thick zinccoating frame
4.H-strength aluminum

Frame made by automatic advanced processing technology, extra-thickness galvanizing layer, antirust. High-strength casting iron impeller, long service life. Reasonable angle blades to ensure the best performance of air flow. Blades automatically open and close with the motor operating to keep from dust entering. Safety net with easy disassembly is convenient for maintenance.

Performance and characteristic

1 Frame using advanced automatic processing, high precision. Extra-thick zinc coating frame, corrosion resistance strong.

2 High-strength aluminum alloy casting wheel, the reasonable perspective of the type ,to reach the maximum air flow .High-precision micro –computer –aided manufacturing system can make the best of its fans.

3 Five rigorous quality testing procedures, noise detection, vibration testing, concentric rotation performance testing, speed of blade testing and the whole fan efficiency detection..380V special motor.
