There are a lot of fan products, today for you to cite a representative one, that is, negative pressure fan. As the latest type of ventilation fan, it has a large exhaust volume, ultra-low energy consumption and low speed and low noise characteristics, and from the structure of the material or price size specifications can also be detailed classification, a qualified negative pressure fan is mainly used for ventilation, for example, for some may produce harmful gases in the workshop or a common kitchen can be seen in the figure, through the work of negative pressure fan can be The work of the negative pressure fan can be carried out in a timely manner for the exchange of indoor and outdoor air, to avoid the loss and trouble caused by the problem.

Three, negative pressure fan and exhaust fan difference
Negative pressure fan and the traditional exhaust fan, compared with its obvious advantages, features outstanding:
(a) good quality: negative pressure fan is the introduction of German technology to produce high-quality negative pressure fan.
(ii) ultra-convenient: negative pressure fan manual shutter control, in the absence of fan operation can be normal light ventilation.
(3) low investment: negative pressure fan single machine air volume, applicable area is wide, is the total investment in central air-conditioning ?1/5, similar ventilation and cooling project with the highest cost-effective.
(4) ultra-environmental: negative pressure fan without compressor, no refrigerant, no pollution, low noise.
(v) very healthy: negative pressure fan for the workshop constantly provide fresh and clean air, increase air oxygen content.
(F) very simple: negative pressure fan easy to install, less maintenance, easy to operate, no need for professional maintenance.
(VII) super durable: negative pressure fan using heavy aluminum die-casting blades, high temperature resistance, no aging, no deformation.
Negative pressure fan on the market has many features and advantages, it can not only ventilation, but also cooling, and energy saving and environmental protection features also make the product is widely used in the field of production and home daily life, for example, some of the workshop may produce odor, including plastic factories, leather factories, then you can see the negative pressure fan to play a key role in addition to the need for cooling, but also for the humidity has a demanding role. In addition, for the need to cool, but also for the humidity has harsh requirements of the place, including chemical fiber factories or knitting factories, you can also see the key role of the negative pressure fan, then the above is about the negative pressure fan on the acquisition of information on various aspects, we also further examples of the difference between it and the exhaust fan comparison.
