According to the stove, it is generally calculated as a furnace head of 2500 3000m h; According to the projection area of the hood, it is calculated according to the wind speed of the projection surface. >>>More
If you are a high-level person, it is useless to have a large amount of light and air, and you have to have a high wind pressure to discharge it.
First, calculate the processing air volume of the fume purifier according to the method of the number of stoves in the kitchen * 4000, and then select the fan with an air volume of 1000 more than the fume purifier. The stove of the general catering store is about 1 or 4, all need 4000 air volume 16000 air volume a little more, you can take a look at our Langxia environmental protection production equipment, honeycomb electric field, to meet the inspection standards of various places.

The minimum exhaust airflow is usually calculated using the following formula: L=2000PH >>>More
Kitchen smoke exhaust, now most of the new house decoration uses range hoods, for range hoods, the state stipulates that the index air volume value is greater than or equal to 7m3 min.
