What is the difference between low-altitude and high-altitude soot purifiers? In recent years, the state and the government have become increasingly strict in environmental protection. Many places, such as restaurants, hotels, barbecue shops, factories, and other places with serious soot exhaust emissions, are strongly required to install soot purifiers. There are many types of oil fume purifiers on the market. In general, they are divided into two types: high-altitude emissions and low-altitude emissions. What are the differences between them?

Definition of low-altitude and high-altitude soot purifiers

Literally, one is a soot purifier installed at a low place, the other is a soot purifier installed at a high place, and the low-altitude soot purifier is to directly discharge the purified gas into the air. The high-altitude exhaust fume purifier means that there is no suitable space to install a purifier in the kitchen or outside the wall. The purifier and fan can only be installed on the top floor of a high-rise building, and the fume needs to be pumped from the lower level to the high-level purification treatment.


Fume purifier efficiency

The low-altitude oil fume purifier is directly discharged to the sensitive area of the oil fume, so the purification efficiency is much higher than the high-altitude oil fume purifier. Generally speaking, the purification efficiency of high-altitude fume purification equipment is 0% -70%, while the purification efficiency of low-altitude fume purification equipment is more than 95%.


Fume purifier price

The purification efficiency of low-altitude exhaust fume purification equipment is high, mainly due to the good quality of the internal materials, high materials, high process requirements, and relatively high price of high-altitude exhaust fume purifiers.


Installation material pipeline requirements

The high-altitude exhaust fume purifier needs to send the purified gas to high altitude before it can be discharged, so it needs to install a long smoke exhaust pipe. The low-altitude exhaust fume hood can directly discharge the purified air into the atmosphere, so the pipeline installation does not need to be too long, which can save material costs.

Oil fume purifier equipment applications

Low-level exhaust fume purifier adaptation field: Low-level exhaust fume purifier equipment is equivalent to direct discharge to sensitive areas, and the exhaust port can be directly discharged outside the window wall without connecting pipes to the roof. Low-altitude emissions are suitable for places without smoke pipes to the top of the building, which are sensitive to the surrounding environment; high-altitude exhaust fume purifiers are suitable for this field: this method is mainly used for large-scale commercial complexes, real estate, large hotels and other projects such as fume purification projects


Market acceptance of fume purifiers

At present, in addition to the National Standard for Fume Emissions in the Food and Beverage Industry, provinces and cities have issued more targeted Food Fume Emission Standards. The lowest standard for fume purification in many places is 90%. Therefore, currently the market has the highest degree of recognition: low-altitude soot purifiers. Due to environmental requirements and stricter emissions testing, the catering industry can only use low-altitude fume purifiers.

What are the differences between low-altitude and high-altitude soot purifiers ? After reading the introduction above, you probably know which one is more suitable for installation in your kitchen. Everyone knows that catering fume is not only harmful to the human body, it can easily induce various diseases if it is inhaled for a long time, and also cause serious pollution to the atmosphere. For human health, reduce air pollution. It is recommended to install a low-altitude soot purifier. Although the price is a little bit higher, installing a low-altitude soot purifier does not need to worry about environmental protection inspections and complaints from nearby residents.
