Product Application
Negative pressure fan is an industrial ventilation device that is manufactured based on the principles of aerodynamics. The core working principle of this device is to generate negative pressure (i.e., lower air pressure inside the room compared to outside) through the operation of the fan, forcing the hot and polluted air inside to be rapidly expelled. At the same time, fresh air from the outside will naturally flow in through windows, doors, or other intake vents, thus creating a continuous and efficient convection cycle. It does not simply blow air into the room; instead, it uses "extraction" to drive "inlet", achieving a thorough ventilation of the entire space.
Advantages
The negative pressure fan has remarkable advantages. Firstly, it has extremely high ventilation efficiency, capable of thoroughly refreshing the stagnant air in large spaces within a short period of time, effectively addressing issues of heat and lack of oxygen. Secondly, it has extremely low energy consumption. Compared to air conditioning systems, its operating cost is only one-tenth or even lower, with outstanding energy-saving effects. Thirdly, it has an economical investment cost, easy installation and maintenance, and an extremely high cost-performance ratio. Additionally, through its powerful exhaust capacity, it can effectively remove dust, moisture, and odors, improving the working environment.
Negative Pressure Fans are widely used in mechanical processing, hardware workshops, welding workshops, lithium battery production workshops, poultry farms, greenhouse cultivation, gymnasiums, etc.
