Blast-It-All Paint Booth Exhaust Ductwork
Blast-It-All abrasive blast and finishing areas need exhaust ductwork that fits the building as well as the process. Double D Mechanical plans duct routes, fan connections, collector access, replacement air coordination, roof or wall penetrations, and utility conflicts around the enclosure and surrounding production space.

Duct Path Through the Building
A practical duct route starts at the booth or room and follows the building constraints outward. Turns, offsets, support points, wall or roof exits, and nearby utilities should be reviewed before field work so the route does not block production or service access.
Dust Collector and Fan Clearances
Collector and fan locations should leave space for filters, motors, cleanout, and inspection. The layout also has to respect forklift traffic, overhead doors, cranes, storage zones, and future maintenance work.
Replacement Air Effects
Exhaust airflow can change how nearby doors behave, how dust moves, and how comfortable the work area feels. Make-up air and surrounding process exhaust should be reviewed together so the blast or finishing area is not fighting the rest of the building.
Walkdown Details to Confirm
Before ductwork is planned, confirm booth dimensions, existing exhaust equipment, roof structure, ceiling height, utility conflicts, collector location options, and shutdown limitations. Photos above the booth and along the proposed route are often as useful as floor-level photos.
Frequently asked questions
Can existing exhaust ductwork be modified?
It may be possible, but the duct condition, size, route, supports, connection points, and process requirements have to be reviewed first.
Why do roof conditions matter?
Roof structure, access, penetrations, curbs, drainage, and nearby equipment can affect where ductwork and discharge points can be placed.
What causes poor exhaust performance?
Possible causes include undersized or damaged ductwork, blocked filters, fan problems, poor replacement air, excessive turns, or changes to nearby building pressure.
When should ductwork be coordinated with other trades?
Coordination should happen before installation so electrical, mechanical, fire protection, structural, and roofing work do not compete for the same space.
