3. The negative pressure fan has a long service life, which can run for more than ten years at least. 4. Free of maintenance and maintenance, the negative pressure fan selects the whole set of sealed type advanced rolling bearings, do not need to be embellished, durable. 5. High efficiency, negative pressure fan only needs a small amount of wind speed, it is very reasonable to improve the office environment in the factory, improve the work efficiency. Can bring you fresh air heat convection, remove heat flow, organic waste gas or smelly air. 6.The main use is wide, negative pressure fan is widely used in agriculture and animal husbandry, aquaculture, industrial production, public places and other manufacturing industries, to improve the natural environment to make contributions.
1. Less power consumption, the use of temperature difference and natural wind to make the negative pressure fan spin, only need light wind or the temperature difference between inside and outside the room, can only drive the turbine blade can be sustainable year-round rotation. High sensitivity, save a lot of money in operation cost. 2. Easy to install, negative pressure fan without motor, no power consumption, noise control, light weight, very light, exhaust system high efficiency, easy to install. Save you a lot of money in labor wages and labor costs.
