Claim 1
Independent Claim
224 words
A powder recovery means for recovering an electrostatic powder from an electrostatic powder coating installation, the powder recovery means including a powder sifting means adapted to receive powder from the electrostatic powder coating installation, a basket means in communication with the powder sifting means in such a manner that the powder sifting means centrifuges a uniform deposit of the powder in the basket means so as to result in a sifting of the powder by the basket means, a container means mounted at the end of the basket means in communication therewith for receiving contaminants from the basket means, filter means cooperable with the basket means for separating powder from a powder-air mixture emerging from the basket means, a base means which is at least partially porous disposed beneath filter means for receiving powder falling from the filter means, suction means for removing the powder from the powder recovery means, pipe means for directly supplying the powder to the sifting means, a single housing means for accommodating the basket means, the base means, and the filter means, and a means communicating with said housing means for transporting the powder sifted by the sifting means and the powder falling from the filter means so as to enable a reuse of the powder, and wherein the single housing means is constructed as a replaceable structural module.

Claim 3
Dependent Claim
49 words
A powder recovery means according to claim 1, wherein an inlet of the pipe means into the sifting means is arranged tangentially thereto, and wherein an air suction means is disposed at one end of the sifting means so as to generate a potential sump in the sifting means.
Claim 4
Dependent Claim
29 words

Claim 5
Dependent Claim
51 words
A powder recovery means according to claim 1, further comprising means for enabling a filtering of the powder in a filter space of the sifting means individually or in blocks so as to enable a continuous opeation of the powder recover means even with the change of pigment in the powder.
