When buying or choosing an oil fume purifier, it is necessary to have a corresponding fan to match it, so as to build a complete oil fume purification system. So when we match the fan air volume, do we need to match whether the air volume is larger or smaller than that of the lampblack purifier? Or match the same air volume?

At present, the types of fans on the market are generally axial flow fans, centrifugal fans and wind cabinets. Axial flow fans are cheap and easy to install, and are generally suitable for self-operated catering units such as small restaurants and restaurants. Centrifugal fans have large air volume per hour, stable performance, low noise and good exhaust effect, but they are relatively large, and are generally used in relatively advanced hotels, restaurants or catering units near residential areas; The air cabinet is a fan with large air volume, good tolerance and excellent and stable performance. It is generally suitable for the central oil fume purification system of large shopping malls or pedestrian streets.

Knowing the types of fans, you need to pay more attention to collocation. What should the collocation of fans be like? Let's talk about it below.

The fume purifier itself has a certain resistance, plus the resistance of pipeline length and elbow resistance. In actual operation, we will find that the purification effect is often not achieved if the fan with the same air volume is matched. This is because the resistance in the fume purifier and pipeline affects the operation of the fan, resulting in a small actual air volume of the fan during operation. Therefore, when we match the fan air volume, we generally need to match a larger purifier air volume, which is generally higher than 10%~20%.
