In principle;suction fan It is designed using the principles of air convection and negative pressure ventilation. Negative pressure fans are installed in poorly ventilated areas. During normal operation, they use mechanical kinetic energy to operate the fan, quickly removing stagnant hot air, odors, and smoke from the factory building in a short period of time. At the same time, they circulate and exchange fresh outdoor air with indoor air, thereby achieving the goal of ventilation, cooling, and improving the workshop environment. The high temperature, stuffiness, smoke, dust, and odor gases in the workshop are all discharged outdoors, indicating that the negative pressure fan is also a smoke exhaust fan& nbsp;
In terms of exhaust volume, the specifications of the smoke exhaust fan are in accordance with the provisions of the "Code for Fire Protection Design of High rise Civil Buildings". The small air volume of the smoke exhaust fan is 7200m/h, and the large air volume should not exceed 60000m/h. It can be seen that negative pressure fans can also be used as smoke exhaust fans& nbsp;
In terms of usage effect, negative pressure fans installed in environments with poor ventilation such as high temperature, stuffiness, and smoke require air exchange once every minute, indicating excellent smoke exhaust effect! In terms of operating costs, the power of the negative pressure fan ranges from 0.37 to 1.1 kW. Using such a small power and large exhaust volume negative pressure fan as a smoke exhaust fan saves a lot of costs. Of course, it should be noted that negative pressure fans can only be used as simple smoke exhaust fans and cannot be applied to machinery equipment or high demand smoke exhaust.
