Why does the powder drift out of the openings of the spray booth?
• Not enough containment air flowing through the booth and recovery system. • Cartridge filters not receiving adequate cleaning. Increase pulse down air pressure or volume. • Cartridge filters nearing the end of their expected life. • Final filters becoming clogged. Note that final filter clogging may be related to poor upstream seals or leakage of powder in the recovery. Why do I need to add virgin powder to my reclaim? As virgin powder is applied, the larger particles more readily stick to the part. This leaves the over sprayed powder with a lower average particle size. As this occurs during each cycle through the system, the recovered material may become laden with fine particles. Eventually, the reclaimed material will be nearly unmanageable in both fluidization and application. What is impact fusion? Friction may cause powder particles to fuse along the walls of the powder hose and other components in the powder delivery path. Impact fusion is the combining of these powder particl
