Negative pressure fan

Negative pressure fans utilize the principle of air convection and negative pressure ventilation for cooling. They work by naturally drawing in fresh air from the opposite side of the installation location (doors or windows), quickly and forcefully expelling stuffy indoor air outdoors. They can improve any poor ventilation problems, achieving a cooling and ventilation effect of 90%-97%.

Features and Advantages

Negative pressure fans utilize the principle of air convection and negative pressure ventilation for cooling. They work by naturally drawing in fresh air from the opposite side of the installation location (doors or windows), rapidly forcing the hot indoor air out. They improve any poor ventilation issues, achieving a cooling and ventilation effect of 90%-97%.

Negative pressure fans extract air outwards through the rotation of the blades, reducing the indoor air pressure and creating a negative pressure zone. Due to the air pressure difference, air flows into the room to compensate. In practical industrial plant applications, negative pressure fans are centrally installed on one side of the plant, with the air intake on the other side, creating a convective airflow from the intake to the negative pressure fan.
