1. A base for a powder coating booth, the powder coating booth comprising a coating compartment for applying a powder coating to an article inside the coating compartment, and the base comprising:
a base structure configured to support the coating compartment;
a floor, supported by said base structure and comprising at least one oblique panel, each oblique panel (i) comprising an upper edge and a lower edge opposite said upper edge, (ii) being inclined with respect to a horizontal plane when the base rests on a ground surface via said base structure, (iii) delimiting a bottom of the coating compartment, and (iv) being porous so as to be air permeable and impermeable to a residual powder from a powder coating of the article within the coating compartment, wherein each oblique panel is attached to the base structure by its lower edge and wherein the base is configured such that pressurized air from a compressed air source is introduced under the at least one oblique panel, and such that the pressurized air thus introduced passes through the at least one oblique panel towards an interior of the coating compartment, to detach the residual powder from the powder coating, as the residual power is present on the at least one oblique panel;
a beam, extending under said at least one oblique panel and supporting each oblique panel by the upper edge of the oblique panel;
at least one anti-vibration pad, attaching the beam to the base structure; and
a vibrator, separate from the pressurized air and from the compressed air source, and supported by the beam, vibrating each oblique panel relative to said base structure, for flowing of the residual powder from the powder coating, as the residual powder is present on the at least one oblique panel, from its upper edge to its lower edge.
