Weather-Rite air make-up units for switchgear cabinets
Switchgear cabinet shells, doors and removable panels need controlled finishing before bus, breakers and controls are installed. Weather-Rite air make-up units are part of the mechanical plan for booths, powder coating systems, ovens and exhaust serving that cabinet flow.

Cabinet Shell Flow
Switchgear cabinets can include deep frames, removable doors, side panels, plinths and small brackets. The finishing layout should reflect whether shells move on carts, hooks, conveyor carriers or lift tables, with enough clearance for coating both exterior faces and interior returns.
Pressure Control Around Open Booths
Open-face paint or powder booths depend on steady capture at the work opening. Weather-Rite make-up air should be positioned and connected so incoming air does not short-circuit across the booth face, disturb powder application or draw contaminants from adjacent fabrication areas.
- Compare make-up air volume with booth exhaust requirements.
- Avoid supply discharge that blows across hanging cabinet doors.
- Review nearby doors, fans and welding exhaust for pressure effects.
Cure Area Mechanical Connections
Cabinet coating lines may use conveyor or static cure ovens, and the air unit installation has to fit around oven exhaust, gas piping, power, controls and safety interlocks. Clear routing helps preserve service access while keeping the line footprint usable for staging and inspection.
Relocation And Retrofit Constraints
Moving a booth, oven or air unit in an active enclosure plant requires attention to roof curbs, existing duct, structural steel, floor openings and utility shutdown sequencing. A realistic plan identifies what can be reused, what needs new connections and what must stay accessible after the move.
Pre-Visit Information
Before a site visit, gather the current layout, the target production flow and the largest cabinet dimensions. Photos of utilities, roof structure, exhaust exits and nearby work areas help Double D Mechanical evaluate installation and connection requirements.

Frequently asked questions
What makes switchgear cabinets demanding in a coating line?
They combine flat panels, deep frames, returns and removable parts, so the line needs good access and consistent airflow around multiple orientations.
Why should make-up air be reviewed with booth exhaust?
The exhaust removes conditioned plant air. Replacement air has to enter in a way that supports capture and does not disturb coating quality.
Can a Weather-Rite unit serve both paint and powder areas?
That depends on the layout, exhaust volumes and process needs. The review should look at each booth, oven and room pressure relationship together.
What can slow down a relocation?
Unknown roof conditions, hidden utility conflicts, limited rigging paths, unclear controls and inadequate service clearance can all affect sequencing.
What drawings are helpful?
Equipment drawings, roof plans, utility plans, duct layouts and a simple production flow sketch are all useful for planning the work.
