The exhaust volume of Gerlinger range hood is only 16.6 cubic meters per minute.

The exhaust air volume is the index of the fan, and the suction effect of the range hood is not only related to the exhaust air volume, but also related to the installation height of the same pot surface. Traditional range hoods, whether Chinese or European, are mostly equipped with suspended ceilings, and the pan surface is far away from the air inlet of the range hood (used for cooking). Once the machine is turned on, the air that does not need to be pumped in the left, right and front directions above the pan surface enters the air inlet first, and then the oil fume at the bottom, so the effective exhaust volume of the real oil fume is less than one third of the original standard value. According to the market marked machine with a maximum of 23 cubic meters per minute, its effective exhaust air volume is less than 10 cubic meters per minute, while Goehringer Tobacco Machine adopts patented wind tunnel rectification technology, with side air intake and close to the pan surface. 16.6 cubic meters of exhaust air per minute is almost used for smoking, but the flame is not affected at all. So as to realize the pumping effect with small displacement and high efficiency. At present, there are also some smoke machine products with side air intake on the market, but they still adopt high hanging mode. Stay away from the pot surface. The fundamental reason is that it cannot solve the problem that the suction effect is good after the height is reduced, but the flame is extinguished by others.
