    Precautions for installing negative pressure fans

    After the wet curtain is blocked, its effective intake area will be greatly reduced, which will affect the wind speed inside the house and the cooling effect of the wet curtain. Therefore, the filter and wet curtain should be cleaned every two weeks. When cleaning the wet curtain, you can first rinse the sediment with a coarse water pipe, and then add a wet curtain cleaning agent such as Ouke to the water tank. Start the cleaning of the biofilm on the surface of the wet curtain and replace it with a clean water source.

    Working principle of negative pressure fan

    Negative pressure is a process of energy conversion that allows air to create convection in the workshop. The negative pressure horn fan is driven by electricity to convert into kinetic energy and wind energy to exhaust indoor air from the outside, thereby reducing indoor pressure. Under the action of atmospheric pressure, fresh outdoor air is replenished from the opposite window and door where the negative pressure horn fan is installed, generating air convection negative pressure.
