Side downdraft paint booths for metal fabrication
Metal fabrication paint areas may coat weldments, frames, enclosures, tanks, guards and brackets that change from week to week. Double D Mechanical installs, relocates and services side downdraft paint booths with attention to part handling, sidewall exhaust, make-up air, utilities and service access.
Discuss your installationPart Variety and Booth Envelope
Fabricated parts vary in height, width, weight and fixture needs. Booth planning should include the largest recurring weldment, the carts or stands used to move it and the operator space needed for edges, corners and underside areas.
Side Draft Capture for Weldments
A side downdraft booth moves air down and toward low side exhaust, which can help with fabricated shapes when the airflow is balanced. Open frames, tubing, stiffeners and recessed areas should be reviewed because they can interrupt capture.
Shop Utility and Duct Coordination
Fabrication shops often have welding circuits, compressed air, cranes, dust collection, mezzanines and crowded roof space. Booth exhaust, make-up air, electrical service, heat and controls should be planned with those systems visible.
Information Needed for a Practical Review
Useful preparation includes part dimensions, fixture sizes, handling equipment, coating process notes, roof conditions, utility capacities and known issues such as filter loading, overspray drift or pressure changes when doors open.
Frequently asked questions
Is a side downdraft booth useful for fabrication shops?
It can be a practical option when part sizes, airflow needs, floor conditions and exhaust routing align with the shop layout.
What parts should be used for sizing?
Use the largest recurring weldments, frames, enclosures, guards or tanks, plus the carts, stands or fixtures that enter the booth.
What makes duct routing difficult in fabrication buildings?
Cranes, structural steel, roof equipment, dust collection, weld exhaust and compressed air mains can all compete for the same space.
Can Double D Mechanical service an existing side downdraft booth?
Yes. Service can address exhaust fans, make-up air, duct connections, filters, doors, pressure balance and related mechanical concerns.
