So which type of spray booth should you purchase? Which best meets your needs and your budget? The answer may seem obvious, but this short comparison may help in the choice you will make.

How They Work:

Pocket Filter Booths
The air to be filtered is pulled through two filters, the pre-filter and the pocket filter, passes the fan, and is then pushed through a final filter, for a total of three filters. The pre-filter, either in a frame or a rolled media, catches the largest particles. The pocket filter has a greater surface area due to the pocket design and collects the smaller micron particles passing through the pre-filter. The final filter collects any particles escaping through or around the other filters and is often considered a safety filter. Filters are cleaned by manually vacuuming the filters.

Cartridge Filter Booths
The dust collector utilizes louvers to aid in the filtration process by forcing a downward airflow, which causes heavy particles to drop to the dust drawers. Particles continue the filtering process by flowing from the outer surface to the inner surface of each cartridge filter medium, leaving the dust on the outer surface of the cartridges. The filtered air flows from the inner surface of the cartridges into the clean air plenum where it is pulled into the fan inlet. The flow continues from the fan inlet to the after filter inner wall if supplied with this option. After air crosses the after filter media, it is exhausted to the environment.
Filter cleaning includes an automatic reverse pulse cleaning system, using dry & filtered 90 PSI compressed plant air. The cleaning mode is activated by a solid-state control timer which signals each solenoid valve in series and opens the air supply valve to clean the filters. Compressed air is passed through a venturi to produce a true pneumatic cleaning of the cartridges. When set-up for adjustable cleaning the cleaning cycles are initiated by a photohelic gauge for automatic cleaning or by a manual switch.

Intended Usage

Pocket Filter Booths
Used in non-production shops with lower usages ranging up 100 lbs of powder per week.

Cartridge Filter Booths
The cartridge spray booth offers a maximum batch powder operation ranging from 50 to 100 lbs of powder per day while providing a dust free and safe environment for powder coating.
