Claim:
A paint shop, comprising at least one painting device incorporating at least one application unit for painting workpieces with a fluid paint and a device for separating fluid paint overspray from a stream of crude gas, wherein the device for separating fluid paint overspray from a stream of crude gas comprises at least one filter device for separating fluid paint overspray from a stream of crude gas which incorporates at least one filter element for separating the overspray from the stream of crude gas and at least one auxiliary material reservoir for accommodating an auxiliary material which is supplied to the stream of crude gas loaded with fluid paint overspray, wherein the auxiliary material reservoir is provided with a balance, wherein an effectiveness of the material contained in the auxiliary material reservoir is determined by a comparison of the weight or the mass of the material contained in the auxiliary material reservoir prior to a whirling-up phase, wherein material is whirled up from the auxiliary material reservoir, with the weight or the mass of the material contained in the auxiliary material reservoir after the whirling-up phase, and wherein the device for separating fluid paint overspray from a stream of crude gas comprises an auxiliary material feeding device for supplying fresh auxiliary material to the auxiliary material reservoir, the auxiliary material feeding device comprising a storage tank for storing fresh auxiliary material and a supply line opening out into the auxiliary material reservoir for conveying fresh auxiliary material from the storage tank to the auxiliary material reservoir.
