The furniture spray booth is a new type of full-pressure dust-free finish room. The basic principle of the full-pressure dust-free paint booth is to use the directionality of the pressure and use the pressure to spray the paint vertically from the top to the bottom to make the painting more precise. In addition, in terms of hardware, there is the main room, which replaces the filter cloth with multi-layer filter cotton, and the air is clean. When the excess paint mist is removed, the water curtain or the environmentally-friendly pumpless water curtain paint machine is more environmentally friendly. In this way, the chance of rework is almost zero, which also saves paint and improves work efficiency.
