Abstract: A method for removing overspray from air flow exiting a painting booth may include passing the air flow through an incoherent mass of cleaning elements, which are kept in a stirred condition, so as to release the overspray onto the cleaning elements of the incoherent mass.

Abstract: A plant for drying objects which release volatile substances may include: a drying tunnel; a conveying system configured to convey the objects through the drying tunnel; a plurality of sensors arranged along the drying tunnel; and/or a plurality of air exchange units. The sensors may be configured to measure a concentration of the volatile substances along the drying tunnel. The air exchange units may be controlled by the sensors to keep the concentration of the volatile substances in the drying tunnel below a pre-established value. A method for keeping volatile substances below a pre-established value within a plant for drying objects may include: measuring with sensors concentration of the volatile substances at points along the drying tunnel; and/or operating air exchange units, according to the concentration of the volatile substances measured by the sensors, to keep the concentration of the volatile substances in the drying tunnel below the pre-established value.

Abstract: A painting booth may include: a painting chamber and/or an overspray removal unit. Paint may be sprayed in the painting chamber. The painting chamber may be crossed by an air flow for evacuation of overspray from the painting chamber. When exiting the chamber, the air flow may pass through the overspray removal unit in order to remove the overspray from the air flow. The overspray removal unit may include an incoherent mass of cleaning elements kept in a stirred condition, through which the air flow containing the overspray passes so as to release the overspray onto the cleaning elements.
