Ventilation Fans: 1) optimized design & construction 2) great air volume 3) steady long-lasting circulation 4) low noise

ZR series heavy hammer exhaust fan

 

 Frame using advanced automatic processing, high precision. Extra-thick zinc coating frame, corrosion resistance strong.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   It used Al-alloy rim ,so it has light weight ,high intension and good toughness.

4   Bearing of impeller, permanently sealed bearing, size 633313,the bearing is of high intension and durable using term without any noise.

5.  High precision system is assistant by computers, which maximizes the effectiveness of the fan. Ten strict procedures that consist of airflow test, noise test, libration test, drive concentric test, blade RPM test, electric current test and whole machine efficiency test, dynamic balance test, the thickness of the galvanized sheet test, the size of the spare parts test, They assure the quality of the fan.

6.  The guarantee period is one year, during which the easily damaged parts are offered free of charge.

7.  Safety net with easy disassembly is convenient for maintaining.

8.  Motor be specially used for high-performance fan, with updated design for automatic regulating device, the belt doesn’t need manual adjustment.
