Ventilation system used by the transmission medium is divided into dust blower fans, explosion-proof fans, fans and other corrosion. Air filter in order to ensure human health and to meet certain industrial processes (such as the food industry, etc.) on the air cleanliness requirements, into the indoor air must be different degrees of purification. In the air supply system used to remove the air filter dust particles in the air, depending on the ore filtration efficiency with fan, air filters into coarse efficiency, in effect, efficient categories. Usually with metal mesh, fiberglass, foam, synthetic fibers and paper as filter material. Ventilation system commonly used treatment methods are harmful gases absorption and adsorption. Absorption method is the use of a suitable liquid as an absorbent in contact with air containing harmful gases, so that the harmful gases are absorbed by the absorbent or react chemically with the absorbent, into harmless substances. Adsorption method is the use of certain substances having a large adsorption capacity of local fan as adsorbent, adsorption of harmful gases. Activated carbon is the most widely used industrial adsorbent. Adsorption method for handling hazardous large low concentration of harmful gases, adsorption efficiency close to 100%. Some harmful gases due to the current lack of economic and effective approach in the case of a last resort you can use high chimney untreated or incompletely treated air into the air. This method is called high-altitude emissions. Centrifugal fan, Shanxi fan (certified), Taiyuan, Shanxi nagorye fan blower is provided by a limited liability company. Shanxi nagorye Blower Co., Ltd.
