I want to buy a blower. Who can tell me how to choose?

Choosing the right fan type is the most basic guarantee for the fan to play its role. Therefore, many users will choose the most suitable fan type according to their own needs and environmental characteristics before using the fan. From what we know, many users still can't master the selection method and the suitable place to use. In view of this situation, we have summarized some methods and skills of correctly selecting fans, so that users can have a good grasp when choosing to use fans.

First, let's learn about the different uses of each fan. According to the different physical and chemical properties of the gas delivered by the ventilator, different ventilators are selected. If transporting explosive and flammable gases, an explosion-proof ventilator should be selected; Dust removal or conveying pulverized coal should choose dust removal or pulverized coal ventilator; Protective ventilators should be selected for conveying corrosive gases; High-temperature ventilator should be selected for working in high-temperature environment or conveying high-temperature gas.

Because of different places, the requirements for ventilation are also different. For example, some high-end places, such as hotels, require to reduce noise as much as possible while ensuring ventilation effect, which brings certain challenges to the use of fans. Therefore, in this case, users can choose those ventilators with higher efficiency and lower impeller peripheral speed to make them work at the highest efficiency point; According to the noise and impact propagation mode generated by ventilation system, corresponding noise elimination and shock absorption measures should be taken. Damping measures for ventilators and motors can generally adopt damping foundations, such as spring dampers or rubber dampers.

If we can fully consider the actual needs of the site in the selection, then the purpose of the selection will be stronger and the selection will be more objective, which will reduce the time and energy of the selection for users and make the use of fans more suitable for the needs of users and sites.
