High-altitude exhaust purifier is to discharge the purified flue gas to high altitude. It is necessary to install the exhaust pipe at the outlet of the exhaust purifier. High altitude exhaust purification rate is relatively low. Generally speaking, the purification efficiency of the high-altitude exhaust purifier can reach 60% - 70%, which is suitable for places with smoke ducts on roofs and no complaints from residents. Prices are also more affordable, reducing costs.
Low-altitude emission means that only high efficiency can be directly discharged from the window. The purification efficiency of the low-altitude smoke exhaust purifier is generally over 95%. The low-altitude emission of flue gas purification in Shandong Province is suitable for roof flue-free, and more sensitive to the surrounding environment. In addition, the low-altitude exhaust purifier can discharge the purified gas directly into the atmosphere, and it does not need to make exhaust pipe at the exhaust port.
Through the above comparison, we can find that the low-altitude exhaust purifier has greater function, higher energy consumption and stronger effect than the high-altitude exhaust purifier, and the price of the exhaust purifier is several times different. However, the two kinds of tail gas purifier equipment can meet the requirements of national environmental protection emission standards. You can choose according to the conditions of the restaurant.
