According to mechanical ventilation products, ventilation equipment can be divided into FRP fan, fire exhaust fan, mixed flow fan, centrifugal fan, negative pressure fan, explosion-proof fan, anti-corrosion fan, exhaust fan, exhaust fan and other products.
Ventilation, also known as ventilation, is to use mechanical or natural methods to send enough fresh air into the indoor space, and at the same time to discharge the dirty air that does not meet the sanitary requirements, so that the indoor air can meet the sanitary requirements and the needs of the production process. The facilities for ventilation in buildings are collectively referred to as ventilation equipment. Ventilation can be divided into full ventilation and local ventilation according to the scope. Full ventilation, also known as dilution ventilation, is to exchange air throughout the space. Local ventilation is to collect and discharge the polluted air directly to the outdoor or directly supply fresh air to the local space at the place where pollutants are produced. Local ventilation has the advantages of good ventilation effect and air volume saving
