The exhaust fan ventilation and cooling system for cooling and ventilating factory plant workshop is designed in the principle of air convection and negative pressure ventilation.

Installed in a poorly ventilated workshop, the exhaust fans can comprehensively exhaust heat, odor, smoke, dust and other gases out from the plant, and at the same time circulate and exchange outdoor fresh air with the indoor to provide freshness for the workshop.

Clean air increases the oxygen content of the air, and improves air quality, it also improves the harsh working environment and protects the health of employees, which is conducive to improving work efficiency.
