There are many fan products, and the representative one is the negative pressure fan. As the latest type of ventilation fan, it has the characteristics of large exhaust air volume, ultra-low energy consumption, low speed and low noise, and can also be classified in detail from the aspects of structural materials or price and size specifications. A qualified negative pressure fan is mainly used for ventilation, for example, it can be seen in some workshops or common kitchens that may produce harmful gases. Through the work of negative pressure fans, indoor and outdoor air can be exchanged in time to avoid the loss and trouble caused by it.

III. Difference between negative pressure fan and exhaust fan

Compared with traditional exhaust fan, negative pressure fan has obvious advantages and outstanding features:

(1) Good quality: negative pressure fan is a high-quality negative pressure fan produced by introducing German technology.

(2) Super convenient: the negative pressure fan is controlled by manual shutters, and it can be used for normal lighting and ventilation when the fan is not needed.

(3) low investment: the negative pressure fan has a large exhaust volume and a wide application area, which is the total investment of central air conditioning? 1/5, similar ventilation and cooling projects have the highest cost performance.

(4) Super environmental protection: the negative pressure fan has no compressor, no refrigerant, no pollution and low noise.

(5) Very healthy: the negative pressure fan constantly provides fresh and clean air for the workshop, increasing the oxygen content of the air.

(6) Very simple: the negative pressure fan is easy to install, requires little maintenance, is convenient to operate, and does not need professional maintenance.

(7) Super durable: the negative pressure fan adopts heavy aluminum die-casting blades, which are resistant to high temperature, aging and deformation.

There are many characteristics and advantages of negative pressure fans in the market, which can not only ventilate, but also cool down. Moreover, the characteristics of energy saving and environmental protection also make products widely used in production fields and daily life at home, such as some workshops that may produce odor, including plastic factories and leather factories, so we can see the key role played by negative pressure fans. In addition, for places that need to cool down but have strict requirements on humidity, Including chemical fiber factory or knitting factory, you can also see the key role of negative pressure fan, so the above is the purchase information about negative pressure fan in many aspects, and we further give you an example of its difference and comparison with exhaust fan.
