(A) the characteristics of negative pressure fan:

The whole machine adopts CAD/CAM design, with low investment cost, large air volume, low noise, small energy consumption, smooth operation, long life, high efficiency characteristics, shutter automatic start and close to achieve dustproof, waterproof, beautiful and generous; It can be both blown and pumped, which is the best choice for cooling and ventilation in modern workshops. The environmentally friendly and energy-saving Yueneng negative pressure fan will become the mainstream of the ventilation and cooling equipment market.

(2) The role of negative pressure fan:

For ventilation: installed outside the workshop window, generally choose the down air outlet, outward suction, and extract odorous gas; There are many applications such as general chemical plants.

Water curtain paper features

1. Water curtain paper is a special paper honeycomb structure material, using a new generation of polymer materials and space crosslinking technology, high water absorption, high water resistance, mildew resistance, long service life.

2. The evaporation surface is larger than the surface, and the cooling effect is more than 80%.

3. No surfactant, natural water absorption, fast diffusion speed, long-lasting effect. A drop of water can be diffused in 4 to 5 seconds, far exceeding the performance indicators of domestic counterparts. The natural water absorption height is 60~70mm/5 minutes, 200mm/hour, which fully meets the international industry standards.

4. It does not contain chemicals such as phenol, which is easy to make skin allergies, and is non-toxic and harmless to the human body when installed and used, and is green, safe, energy-saving, environmentally friendly and economical.

2.【Scope of Application】

1. Almost all places that need to be cooled, ventilated and ventilated can be used, such as commercial factories, supermarkets, offices, hotels, hospitals, stations, gymnasiums, dance halls, auditoriums, Internet cafes, schools, factory workshops and other places.

2. Suitable for high temperature or odor industrial production workshop, such as chemical plant, textile factory, electronics factory, machinery factory, etc., can also be used for posts or comprehensive cooling ventilation.

Fan + wet curtain = negative pressure cooling 1/3 of the cost of air conditioning investment, 1/8 of the air conditioning operating cost can make the plant always remain below 30 degrees.

Regardless of your plant: at a high temperature of 35 ° C to 45 ° C; Or dust, smell is very strong: or poor ventilation, very stuffy, we have a reasonable and effective solution, can keep your company's plant temperature between 26 ° C -30 ° C, to create a comfortable working environment, thereby improving your company's work efficiency.
