The difference between them is mainly a purification effect difference. The high-altitude purification rate is relatively low, only about 61%, which is suitable for places where smoke pipes reach the roof and there are no complaints from residents. Although the price is cheap, the cost is also low. But there is no effect of removing soot at all. Low-altitude emission is suitable for places where there is no smoke pipe to the roof, the environment is sensitive, and there are complaints. The most important thing is that the smoke removal effect at low altitude is much higher than that at high altitude, and the most important thing is that it can be visually smokeless.

1. Purification efficiency

According to their names, we can also draw the conclusion that high-altitude fume purifier equipment is to discharge the purified fume into the high air, while low-altitude fume purifier equipment is to directly discharge the purified gas into the air. Low-altitude fume purifier equipment is equivalent to being discharged into sensitive areas, so the purification efficiency is much better than that of high-altitude fume purifier equipment.

Generally, the purification efficiency of high-altitude fume purifier equipment can reach 61%-71%, while the purification efficiency of low-altitude fume purifier equipment is over 95%. However, the gas purified by these two kinds of lampblack purifier equipment can meet the national environmental protection lampblack emission standards, that is, only at low altitude.

Second, the price

Relatively speaking, the purification efficiency of low-altitude fume purification equipment is high, and the quality of internal materials is good, so people who are knowledgeable in the market know to choose low-altitude equipment.
