Negative pressure fan cooling system ventilators with BLDC motor

The negative pressure fan uses the cooling principle of air convection and negative pressure ventilation.

It is a kind of natural intake of fresh air from the opposite side of the installation site --- the door or window, and the hot indoor air is quickly discharged out of the room.

The  cooling effect of fan is 90%-97%.

The whole machine adopts CAD/CAM design, which has the characteristics of low investment cost, large air volume, low noise, low energy consumption, stable operation, long life, high efficiency, etc.

The shutters automatically open and close to achieve dustproof, waterproof, beautiful appearance; it can be blown, it can also be exhausted, which is the best choice for cooling and ventilation in modern workshops. Environmentally friendly and energy-saving negative pressure fans will become the mainstream of the ventilation and cooling equipment market.

The scope of application of negative pressure fan:
A. Suitable for workshops with high temperature or peculiar smell: such as heat treatment plants, casting plants, plastic plants, aluminum profile plants, shoe factories, leather goods plants, electroplating plants, printing and dyeing plants, various chemical plants.
B. Suitable for labor-intensive enterprises: such as garment factories, various assembly workshops, and Internet cafes.
C. Ventilation and cooling of horticultural greenhouses and cooling of livestock farms.
D. It is especially suitable for places that need to cool down but also need a certain amount of humidity. Such as cotton mills, woolen mills, linen mills, weaving mills, chemical fiber mills, warp knitting mills, texturing mills, knitting mills, silk weaving mills, socks mills and other textile mills.
E. Applicable to the field of warehousing and logistics.
