Smoke exhaust fan selection

1. Model. The model of the exhaust fan is basically formulated by the state. Generally, as long as the model is known, the problem is basically solved by half;

    2. Is it high temperature? Some places are necessary to prevent high temperatures, especially high-temperature gases. At this time, we choose fire-fighting fans, and we should choose high-temperature fire smoke exhaust fans;

   3. Oblique or mixed flow. Although the gap between the two is not great. However, if there are requirements in this regard, the selection will be simpler;

    4. Is it low noise? This is relatively simple and does not explain;

    5. The fan model can be determined by parameters such as air flow, voltage, full pressure, and power.
