Paint booths in the furniture industry can be divided into two categories: dry booths and wet booths (water treatment).

Generally, dry treatment is mostly used in furniture painting booths, and the filtration system is composed of primary filter cotton, intermediate filter cotton, etc. The filtration system needs to be checked and replaced regularly, otherwise it is easy to affect the quality of the baking paint and may even cause a fire. Paint room air purification system: the filter system device adopts two filter layers, the coarse filter layer captures dust particles with a diameter of more than 10 μm, and the precision high-efficiency filter layer has a multi-layer structure, which can capture dust particles with a diameter of more than 4 μm, and the whole filter system has a large dust holding capacity, low resistance, long life, and the filtration efficiency can be more than 98%.

The working principle of the furniture paint spraying room: when painting, the outside air is primarily filtered by the air inlet, and then sent into the static pressure room of the paint room by the blower, and flows into the paint room operation space after the top filter cotton is filtered twice, and the air flow forms an air curtain around the workpiece from top to bottom. At this time, there is a loaded wind speed of >0.3m/s in the paint room, and the paint mist produced by the spray paint will not stay at the operator's breathing zone, but with the rapid decline of the airflow, the airflow is filtered by the bottom water and discharged by the exhaust duct at high altitude.
