FIELD: process engineering.
SUBSTANCE: invention relates to automotive industry, particularly to chambers for paint spray application at overpressure. In compliance with this invention, auxiliary material is added in crude gas flow loaded by over spraying of wet lacquer. Said auxiliary material is added before gas flow passes through, at least, one filter for separation of excess spray from gas flow. Then, defined is sufficiency of gas flow through sand filter. In case there is no sufficient gas flow there through, auxiliary material addition is blocked. Proposed device comprises device to define sufficiency of aforesaid gas flow amount. Besides, it comprises device to block addition of auxiliary under above described conditions. Besides, it incorporates the device to separate exceed spray of wet lacquer and painting device to paint, mainly, car bodies.
EFFECT: stable and uninterrupted operation.
