Priciple of negative pressure fan: The negative pressure fan is designed according to the air convection and the principle of the negative pressure ventilation. The negative pressure fan is usually installed in poor ventilation places. When it is working, it will force out the stagnant hot-gas, peculiar smell and squalid smoke bythe negative pressure rapidly in the shortest posssible time. At the same time, fresh air will be supplied into the door quickly and flow circularly, so as to achieve the aim of ventilation and cooling and improve the workshop's environment.
