Negative pressure fans use the cooling principles of air convection and negative pressure ventilation to effectively discharge indoor high temperature, odor, dust, smoke and turbid and stuffy air to the outside to achieve the effect of continuous ventilation. It is especially suitable for areas with many heat sources. Factory buildings, such as die-casting plants, etc.

Utilizing water evaporation to take away a large amount of latent heat to achieve natural evaporation cooling is currently an internationally recognized technology with high refrigeration efficiency.

Water evaporates and absorbs heat. According to this principle, when water flows downward from the upper part of the wet curtain under the action of gravity, a water film will be formed on the surface of the corrugated fiber material; when the flowing air passes through the wet curtain, the water in the water film will absorb the heat in the air. Evaporate, thereby taking away a large amount of latent heat, reducing the temperature of the air passing through the wet curtain, achieving cooling, cooling and humidification purposes.

The large air volume ceiling fan allows the air to flow throughout the cooling area. The flowing air flow allows the sweat on the skin surface of the area staff to evaporate and take away the heat on the skin surface, thereby cooling the human body or animals, and the body temperature drops by 2-3, improving comfort.

The pulse dust removal filtration efficiency reaches 99%: it can directly emit unorganized emissions, and it occupies a small area: it can be installed directly inside the workshop.
