Abstract: A rotary carousel device for spraying a coloring and/or treatment product, that includes at least one rotary support rotatably driven by a motorized device on at least one chassis around a rotational axis. Further, one or more spraying devices are in communication with a pressurized feeding system composed of at least one pump and a set of feeding pipes. The set of feeding pipes comprises an on-board pipework arranged on the rotary carousel device, and an external pipework arranged to link the on-board pipework and at least one product tank. A fitting or rotary seal connection system is mounted on the rotational axis, connecting the on-board pipework and the external pipework. Wherein the at least one pump being arranged on the rotary carousel device and being coupled to the external pipework and to the on-board pipework, to provide the product to a desired pressure at the spraying device.

Abstract: A filtration installation including a time delay device which, at the time of a filter sleeve cleaning operation, establishes a cycle to exhaust filtered air towards the outside atmosphere instead of recycling it. The installation also includes a device for bypassing the filtered air that includes two shutters. One of the shutters controls a recycling of the filtered air and the other shutter controls the exhaustion of the filtered air to the outside atmosphere.

Abstract: Process and apparatus for filtering air in a cyclone filter by reducing the ascending speed of air to be filtered in the lower part of the filter by providing a skirt on the filter cartridge. Perforations are included in the skirt, which make it possible to increase the intake surface for the air at the lower intake of the skirt. Moreover, the diameter and density of the perforations are adapted according to the type of dusts and wastes suspended in the air.
