1) frame using advanced automatic processing, high precision. extra-thick zinc coating frame, 120g/m²,thickness 1.0mm corrosion resistance strong.

2) 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.

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