Principle:
Exhaust fan is installed in one side and evaporative cooling pads is installed in the other side, then heat and exhaust inside will be taken away because of negative pressure, and fresh and filtered air will be pumped into through pad to make the air cool down by natural physical phenomenon---evaporation.
Feature:
1. Six blades design is for increasing airflow owing to the blade is make of the high strength metal(aluminum).
2. Shutter can ensure the shutter open and close autimatically, and makes it dustproof, waterproof in centrifugal industrial ventilation/exhaust fans.
3. The motor enjoys high efficiency and energy-saving, which makes it possible to work easily under the high pressure surrounding.
4. Autimatic tensioner is adopted in industrial ventilation / exhaust fans to prevent the belt loosing and dropping off.
