Introduction to the Ventilation Principle of Negative Pressure Fans

Source： Time：2024-07-08 14:45:52 views：

suction fan Discharging air outward causes a decrease in indoor air pressure, making the indoor air thinner and forming a negative pressure zone. The air compensates for the pressure difference and flows into the room. In practical applications of industrial plants, negative pressure fans are centrally installed on one side of the plant, with the air inlet on the other side of the plant. Air flows through the air inlet to the negative pressure fan to form convective blowing. During this process, the doors and windows near the negative pressure fan remain closed, forcing air to flow into the workshop through the compensating doors and windows on the intake side. The air flows into the workshop in an orderly manner through the air inlet, passes through the workshop, and is discharged from the workshop by a negative pressure fan. The ventilation rate can reach up to 99%. Through specific engineering design and the design of ventilation speed and velocity as needed, high heat, harmful gases, dust and smoke can be quickly discharged from the workshop, and poor ventilation problems can be solved in one go. The ventilation effect can be achieved within a few seconds of turning on the fan.
