Air Make-Up Units for Switchgear Enclosure Finishing
Switchgear enclosure finishing areas often combine sheet metal fabrication, wash or prep, powder or liquid coating, and cure equipment. Double D Mechanical installs, relocates and services air make-up units that replace exhausted air from finishing processes while coordinating ductwork, utilities, controls and maintenance access.
Discuss your installationAir Support for Enclosure Coating
Panels, doors, cabinets and welded frames need steady airflow through prep and coating areas. Air make-up should replace booth and oven exhaust without disturbing spray patterns, powder containment or part movement. The layout should consider carts, racks, conveyor openings and staging near the finish line.
Duct Paths Around Production Lines
Switchgear enclosure plants may have lasers, brakes, weld cells, washers, booths and ovens close together. Duct routing should avoid blocking maintenance doors, conveyor access, crane paths or aisle space. Unit placement should also keep outdoor intake and service areas clear.
Utilities and Process Sequencing
Air make-up equipment may need power, fuel, control signals and dampers coordinated with exhaust fans and finishing equipment. Sequencing with electrical, controls and building trades helps ensure the unit operates with the process rather than as a stand-alone air source.
What to Prepare for Review
Before a site visit, gather line drawings, exhaust requirements, enclosure size ranges, utility locations, roof information and photos of current airflow problem areas. For a relocation, include the intended equipment sequence and any production windows that constrain the move.
Frequently asked questions
What finishing equipment commonly affects make-up air needs?
Paint booths, powder booths, washers, ovens and general exhaust points can all affect replacement air requirements.
Why does enclosure size matter?
Large cabinets and frames affect aisle clearances, rack movement, booth openings and where discharge air can be introduced without disrupting work.
Can an air make-up unit help with pressure problems near a coating line?
It may help when the issue is tied to exhaust air replacement. The full ventilation layout should be reviewed before changes are made.
What maintenance space should be protected?
Keep access to filters, fans, dampers, burner components, control panels and any roof or platform service points.
