Abstract
Abstract A painting booth such as for painting vehicles and the like which is a light and inexpensive construction and adapted to produce a good air circulation and purification in the booth while avoiding excessive turbulence and the related poor quality of painting and the fire hazards resulting from local concentration of inflammable paint solvents. This painting booth is characterized by a light steel framework, an air filtering pervious skin such as of canvas to pass the incoming air therethrough, externally mounted lighting fixtures avoiding the need for special flameproof light fixtures, and an air filtering and purifying unit extending through a wall of the booth and remotely exhausting the air and paint solvents after filtering out of the paint particles by washable filter screens.
