Product Description


Provide a safe working environment: In some industrial applications, negative pressure fans can be used to control air flow and ensure that the work area is kept at a low pressure to prevent hazardous substances from spreading to the surrounding environment. This helps protect workers from exposure to hazardous substances.

Push pull type negative pressure exhaust fan

Improve air quality: Negative pressure fans provide powerful extraction that helps to remove airborne contaminants such as smoke, dust, odours and moisture. By keeping the air fresh and circulating, they improve indoor air quality, creating a more comfortable and healthy environment.
Flexible and Adjustable: Negative pressure fans typically have adjustable airflow and speed controls to suit different applications. Users can adjust the fan's operating parameters to obtain optimal ventilation and energy control.
