Why Choose Us
Centrifugal fans

Thermally Protection with Better Insulation

One body injected insulation case provides better insulation between coil and silicon steel. Thermal protector prevents motor overheating.
Centrifugal fans

Electricity Saving

The conversion efficiency of our fans is generally about 10% higher than other manufacturers by applying Advanced Geometry design.
Centrifugal fans

Longer products lifetime

The winding of our fan motors is 100% made by copper. Using good quality wire bring longer life expectancy to all series of fans.
Centrifugal fans

Stronger Impeller Structure

One body injected impeller has stronger structure and better balance compared with impeller mounted with a metal plate.
