English term or phrase:a textile filter at a number of suction points
The painting boxes have separate ventilation systems controlling the incoming air at different places around the box. Outgoing air is sucked through ***a textile filter at a number of suction points*** on the walls or in the floor, depending on the chosen construction. The textile filter cleans the air from possible paint particles.
