Booth Exhaust Systems for Switchgear Cabinet Coating
Switchgear cabinet booths rely on exhaust systems that capture overspray or airborne powder while supporting consistent airflow around tall shells and panels. Double D Mechanical installs, relocates, and services booth exhaust fans, ductwork, stacks, and related mechanical connections for industrial finishing operations.
Discuss your installationCapture Around Large Enclosures
Cabinet shells can block airflow differently than flat panels, especially when doors, frames, and deep interiors are present. Exhaust design and installation need to account for booth style, filter arrangement, workpiece position, and operator movement. A practical layout keeps air moving through the intended path while leaving room to load, ground, coat, and inspect parts.
Ductwork, Fans, and Stack Routes
Exhaust systems must fit the building as well as the booth. Duct routes may pass through roof structure, wall openings, mezzanines, or crowded utility zones. Double D Mechanical coordinates duct supports, fan placement, stack routing, transitions, access doors, and service clearances so the system can be maintained after installation.
- Confirm booth dimensions, filter layout, and exhaust collar locations.
- Review roof or wall penetration points before equipment is set.
- Keep cleanouts, fan motors, belts, and dampers reachable for service.
Balancing Exhaust With Replacement Air
A booth exhaust system removes air from the finishing area, so make-up air and building pressure should be reviewed early. Poor balance can affect booth containment, powder recovery, paint transfer, oven draft, and nearby doors. Exhaust changes should be coordinated with air make-up units, cure equipment, and any neighboring processes that also move air.
Planning for Repair or Relocation
For existing systems, document fan condition, vibration, duct damage, filter loading patterns, stack condition, and any access problems. For relocation, current equipment measurements, photos, disconnect points, roof details, and proposed booth location help determine how much of the exhaust path can be reused or should be revised.
Frequently asked questions
What causes poor booth exhaust performance on cabinet work?
Common causes include blocked airflow around large parts, loaded filters, undersized or damaged ductwork, fan issues, inadequate replacement air, and changes to the booth layout.
Can exhaust ductwork be routed through an existing roof opening?
Sometimes, but the opening, structure, stack location, and equipment layout must be checked against the new booth and fan requirements.
Why review make-up air with exhaust work?
The booth cannot exhaust air reliably if the building cannot replace it. Make-up air helps maintain a more stable pressure relationship around the finishing area.
What maintenance access is important?
Filters, plenums, access doors, dampers, fan motors, belts, bearings, and stack connections should be reachable without disrupting normal production areas.
What information helps with an exhaust system site visit?
Booth drawings, fan data, duct photos, roof details, cabinet dimensions, current airflow concerns, and utility or structural constraints are all useful.
