Dust Control Booths & Rooms

Isolation of “dirty” areas or processes within a facility is a means to control plant indoor air quality. Containing the airborne materials and subsequently filtering the collected air maintains a healthy workspace. The booth structure simply encapsulates the polluting source. The design considers the following: materials being collected, required carrying velocity, the position of worker (s) to the exhaust air intakes, and where the cleaned air is directed, either back to the booth, room, or to a remote location. Dust, fume, odor, and mist are all materials that can effectively be captured, but efficiency can be affected by the time the material stays in suspension and the distance from the source to the inlet of the filtration device.

Enclosing a dust source and containing the “dirty air” in a walk-in booth, or enclosure, minimizes the total amount of airflow required. The dust control enclosure encapsulates processes in a facility where materials are often blown around by cross drafts, man coolers or compressed air, tracked around by forklifts or launched into space by rotating equipment like sanders and grinders. All of which creates issues in other areas of the plant.

Enclosure construction (varies with size of the enclosure) is a structural tube framework with walls and roof of CS or SS sheet metal, vinyl sheeting, or noise blanketing. Integral to the enclosure can be an air filtration bank, renewable cartridge dust cleaner or wet scrubber to filter the collected airstream material. Mounting the filtration unit remotely is an option.

Recently, air cleaning of large in-place rooms where large assembles are being processed, fabricated or assembled, has effectively been addressed by installing air filtration modules or units into an end wall. Careful positioning of the processes and workers needs to be included in the final design.
