Booth Exhaust Systems for Fabricated Metal Parts
Booth exhaust systems pull overspray, vapors or airborne process material away from fabricated metal parts and operators during finishing. The exhaust layout has to fit the booth type, part presentation, building structure and make-up air strategy. Double D Mechanical installs, relocates and connects exhaust ductwork, fans, stacks and related components with attention to airflow, service access and coordination with other trades.
Discuss your installationAirflow Across the Work Area
The exhaust system should support the booth airflow pattern around racks, carts, hanging parts or stands. Part size, booth opening, filter location and operator position all affect how air moves through the finishing area.
Duct Route and Fan Location
Ductwork may need to pass through crowded ceilings, roof framing, exterior walls or mechanical spaces. Fan placement should consider service access, vibration, discharge location and coordination with roof curbs or structural supports.
Make-Up Air Relationship
Exhaust air must be replaced in a way that does not disturb coating patterns or pull dust from adjacent plant areas. Exhaust planning should be reviewed with air make-up, building pressure and nearby doors or loading areas.
Filter and Plenum Service
Filters, plenums, access panels and cleanout points need to remain reachable after installation. The layout should leave room for routine maintenance without blocking booth doors, aisles or part staging areas.
Walkthrough Details to Bring
Gather booth drawings, fan data, part handling method, desired duct route, roof or wall access, make-up air information and photos of the booth area. Existing exhaust concerns such as odor movement, weak capture or access problems should be noted.
Frequently asked questions
What determines exhaust duct size and route?
Booth design, airflow requirements, fan selection, building structure, discharge location and available space all influence duct sizing and routing.
Can exhaust ductwork be changed during booth relocation?
Yes. Relocation usually requires reviewing the new duct path, fan location, roof or wall penetrations, controls and make-up air relationship.
Why coordinate exhaust with make-up air?
Supplying replacement air in the wrong location can disturb booth airflow or create pressure problems in nearby spaces.
What maintenance access matters most?
Access to filters, plenums, fan belts or motors, dampers, cleanouts and roof or exterior components should be maintained.
What should be ready for an exhaust review?
Have booth drawings, fan information, photos, existing duct routes, roof access notes, utility conflicts and any airflow concerns ready.
