The machine uses CAD / CAM design, with low investment costs, air volume, low noise, low energy consumption, stable operation, long life, high efficiency, shutters automatically shuts dust, water, beautiful; both hair, but also ventilation, modern workshop is the best choice for cooling ventilation. Environmental protection, energy saving ventilation and cooling suction fan will become the mainstream equipment market.

Suction fan Scope:

A, suitable for high temperature or smell of workshop: such as heat treatment plant, casting plant, plastics plant, aluminum factories, shoe factories, leather factory, electroplating plants, a variety of chemical plants.

B, applicable to labor-intensive enterprises: such as garment factories, various assembly plant, cafes.

2, the installation environment select the outlet, the outlet should be noted that the opposite can not have too much of an obstacle within 2.5 -3M.


1, the installation smoothly: should pay attention to the horizontal position of the suction fan is installed fans to adjust to the level of suction fan and a solid foundation plane. After installing the motor can not have tilt.

2, the installation suction fan bracket, be sure to let stand firm and level ground plane, re-install Jiaotie reinforcement if necessary beside the suction fan.
