Spray-Tech/Junair Paint Booth Exhaust Ductwork
Spray-Tech/Junair paint booth exhaust ductwork has to move air out of the booth without creating service headaches, roof conflicts, or airflow problems. Double D Mechanical plans and installs duct routes, fan connections, and related mechanical work with the booth and building conditions in mind.

Duct Routing Through the Facility
The shortest path is not always the best path. Exhaust routing has to consider roof structure, wall openings, overhead utilities, cranes, mezzanines, sprinklers, and future maintenance access. A route that avoids production conflicts can save trouble long after installation.
Fan Connections and Access
Fans, transitions, dampers, and supports should be installed so they can be inspected and serviced. Access to belts, motors, bearings, cleanout points, and fasteners matters when the booth is running every day.
Balancing Exhaust With Replacement Air
A booth exhaust system removes air that must be replaced. If make-up air is undersized or poorly located, the booth can pull from doors, offices, or process areas, causing drafts and inconsistent spray conditions.
Details to Confirm Early
Useful planning information includes booth drawings, exhaust volume requirements, discharge location preferences, roof construction, nearby outdoor air intakes, and the plant's production schedule. Early decisions reduce rework around steel, roofing, and utility conflicts.
Frequently asked questions
What causes poor exhaust performance in a paint booth?
Common causes include loaded filters, incorrect fan rotation, restrictive duct routing, damaged dampers, poor make-up air, leaks, and obstructed discharge points.
Can existing exhaust ductwork be reused?
It may be possible after checking size, condition, routing, support, discharge location, and compatibility with the booth and fan requirements.
Why is duct access important?
Access allows maintenance teams to inspect fans, clean sections, check connections, and address wear without tearing into finished building areas.
What should be available before ductwork installation?
Booth drawings, fan data, roof plans if available, utility locations, structural constraints, and any required shutdown windows should be ready.
How does exhaust ductwork affect booth airflow?
Restrictions, leaks, poor transitions, or an imbalanced fan can reduce capture and change how air moves across the workpiece.
