Working Principle of Negative Pressure Fan Nederland

The negative pressure fan adopts the design of the physical principle of negative pressure ventilation and air convection, and uses the knowledge of fluid mechanics to scientifically and rigorously calculate and design the fan Angle, motor power, speed, wind pressure and air volume. When the fan is powered on, it can quickly reach a large amount of exhaust air, so that the indoor environment can quickly produce an air pressure difference between the outdoor and the indoor environment, forming a strong negative pressure. Forced indoor dirty sultry air must be quickly discharged in accordance with our set flow direction, indoor air pressure drops, the air becomes thin, forming a negative pressure area to discharge outdoor at the same time, forced outdoor fresh air along the pressure difference compensation into the room, so as to achieve the workshop factory exhaust smoke, exhaust heat, exhaust dust, ventilation and air circulation cooling effect.

In practical applications, the negative pressure fan is often centrally installed on one side of the plant, and the air intake is located on the other side of the plant, and the air is formed by the air intake to the negative pressure fan. In this process, the doors and Windows near the negative pressure fan should be kept closed, the forced air is compensated by the doors and Windows on the air intake side into the factory building, flows through the factory building, and is discharged by the negative pressure fan, and the ventilation rate can be as high as 99. Through scientific and reasonable design, any high heat, harmful gases, dust and smoke can be quickly discharged from the workshop, and problems such as poor ventilation can be solved at one time.
