At present, there are many kinds of fume purification equipment in the world, and the price fluctuates greatly, so it is difficult for ordinary people to distinguish the advantages and disadvantages. Let me talk about the price of electrostatic fume purifier. Regular A-class electrostatic fume purification equipment with 4000 air volume has been installed for about 5000 yuan. If you install it yourself and buy it online, it will cost about 3000 yuan. 4000 air volume can basically meet the needs of a main stove, generally operating a fried restaurant. 6000 air volume can meet the needs of two main stoves. However, it is recommended that a main furnace be installed with 6000 air volume. And the price is around 7000 yuan. The advantages of oil fume purification equipment are not small.
