摘要

A powder recovery module (9) having one face (22) for removably mounting to a powder spray booth (3) wall comprises at least two tangential feed cyclone separators (11). Channel means are provided to withdraw at least some of the air-entrained powder from a position close to the floor of the booth (3) and to supply a steady flow of constant air/powder density to each of the cyclone separators (11). The cyclone separators (11) are suitably configured and disposed so as to maximise their efficiency whilst minimising the volume of the module (9) and time required to clean the cyclone separators (11) when changing to spraying with a different colour powder.
