Principles Negative Pressure Fan
discharging air to make indoor air pressure drop, indoor air getting thinner and form a negative pressure zone.The air into the indoor because of differential pressure. In the practical application in industrial workshop, negative pressure fan installed in the factory side, air inlet on the other side of the plant room.Then it formed a negative pressure zone between Negative pressure fan and air inlet. In the process, the doors and Windows near the negative pressure fan keep closed and forcing air into from air inlet doors and Windows to workshop. Air lined up then orderly by the air inlet into the workshop and through the workshop, finally,the negative pressure fan discharge air from workshop. Thoroughly, efficient ventilation and air change rate can be as high as 99%. Through specific engineering design and according to the need for air speed and wind speed and no heat, dust and harmful gases, smoke quickly discharge from workshop.Any problem of poor ventilation can completely solve once only. From the open fan ventilation could be achieved within a few seconds. Product Description
