Now it is clearly stipulated that only Beijing can purify non-methane total hydrocarbons? At present, the emission requirement of non-methane total hydrocarbons in Beijing catering industry is that the concentration should not exceed 10mg/m? The purification rate of small catering units is higher than 65%, that of medium catering units is higher than 75%, and that of large catering units is higher than 85%.

GOJEK's fume purifier has the function of purifying non-methane total hydrocarbons, and the purification rate is above 90%, which is no problem after passing the EIA.
