Recovery and conveyorized system for powder booth
A powder booth is an enclosure that is designed to contain the powder application process.
A recovery system is attached to the powder booth shell. The recovery system uses a fan to pull air into the booth and prevent the oversprayed powder from migrating out of the enclosure. The simplest powder booths are designed for a single operator to manually apply powder to a stationary product. Other booths are designed so that parts can be conveyed through the enclosure.
Conveyorized systems may be designed for manual application from two sides, automatic application, or a combination of both, depending on the system requirements. The particular style, size and number of powder booths needed is related to the product size, the available space, the amount of capital and the volume of product to be coated.

Material of booth wall
Powder booth shells are occasionally made of painted steel but more often they are made of stainless steel, polypropylene, polycarbonate or other clear plastic, and a few are made of glass or polyethylene sheet.
Painted steel is adequate but there is some risk that the paint will chip off and contaminate the oversprayed powder in the reclaim system.
Stainless steel makes a very durable booth shell with a smooth surface for ease of cleaning.
Plastic walled booths offer an easy to clean surface and the walls can allow some light to penetrate into the spray area and help illuminate the process. A nonconductive plastic walled booth will collect less charged powder on the walls. This means that they can be easier to clean. It also means that they do not attract as much powder that might otherwise be attracted to the part, so the yprovide a modest improvement in transfer efficiency.
