Paint Booth Exhaust Ductwork for Electrical Switchgear Enclosures
Switchgear enclosure finishing often involves tall cabinets, doors, frames, panels, and welded bases moving through prep, paint, cure, and inspection. Double D Mechanical installs and connects paint booth exhaust ductwork with attention to airflow, fan placement, make-up air, structural clearances, and service access around active enclosure production.
Discuss your installationDuct Paths Around Tall Cabinets
Electrical enclosures can require high door openings, crane lanes, cart paths, and staging space beside the booth. Exhaust ductwork should be routed so it does not crowd the movement of cabinet bodies, panel racks, or lift equipment. Roof penetrations, wall exits, and overhead supports need to be reviewed against the real production path, not only the booth footprint.
Airflow for Flat Panels and Deep Frames
Large flat panels and deep cabinet frames can interrupt airflow differently. Duct sizing, fan location, filter bank access, and make-up air delivery should support steady capture across the spray zone while keeping painter movement practical around the workpiece.
Utilities and Trade Sequencing
Exhaust duct installation often intersects with electrical feeds, compressed air, gas piping for heated air, controls, lighting, fire protection, and roof work. Early coordination helps avoid conflicts between duct supports, cable trays, sprinkler runs, and other systems serving the finish area.
Details to Have Ready
A focused site visit is easier when the plant team can show the expected part mix, booth location, and building conditions.
- Maximum enclosure height, width, and handling method.
- Existing booth drawings, fan data, and filter arrangement if available.
- Preferred roof or wall exhaust route and known obstructions.
- Locations of electrical, gas, compressed air, and make-up air equipment.
Frequently asked questions
What makes exhaust ductwork different for switchgear enclosure booths?
The workpieces are often tall, boxy, and moved on carts or lifts, so duct routing must protect overhead clearance, staging space, and service paths around the booth.
Can existing exhaust ductwork be reused?
Sometimes, but it should be reviewed for condition, route, fan compatibility, support, access, and whether the current layout still fits the new booth or production flow.
Why is make-up air reviewed with exhaust ductwork?
Exhaust removes a large volume of air from the room. Replacement air needs to enter in a way that supports booth airflow without creating drafts or pressure problems in nearby work areas.
What access should be preserved after installation?
Filter changes, fan service, damper access, roof access, control panels, and clear aisles for moving enclosures should remain workable after the ductwork is in place.
