How does the powder coating booth recyle excess powders?

Use a powerful fan motor draw air to the powder booth forming negative pressure in the chamber, which prevents powder escaping outside. During the powder coating, excess powders and airflow pass through the cartridge filters, then clean air is discharged to the atmosphere. The powders accumulate on the cartridge filters, as the pulse-jet filters works by solenoid valve, powders are cleared from the filters and drop to a removable powder collector. Thus the powder utilization reaches high and the filter life is extended.
