Booth Exhaust Systems for Georgia Paint and Coating Operations
The exhaust system is the part of a paint booth that actually removes overspray and solvent vapor from the building. Fan, motor, duct, stack and filters all have to be sized together, because a booth that looks perfect inside will still fail if the fan cannot pull through loaded filters or the stack discharges back toward the intake. Double D Mechanical installs, replaces and services booth exhaust systems for Georgia finishing operations.
Discuss your installationExhaust for Large Electrical Steel Booths
Booths sized for large electrical equipment, the type of product made at plants like the Virginia Transformer facility in Rincon, move a great deal of air. Exhaust fans for those booths are large, often mounted on the roof or on a platform outside, and the duct is big enough that supports, roof structure and weather sealing all need engineering attention. Small changes in duct routing can add significant static pressure, so routes are kept as short and straight as the building allows.
The Pieces of a Booth Exhaust System
Every exhaust system we install includes these elements.
- Exhaust filter plenum and filter frames matched to the booth
- Fan and motor selected for airflow at loaded-filter static pressure
- Duct with access doors for inspection and cleaning
- Stack height and discharge direction chosen to clear the roof and avoid re-entry
- Manometer showing filter pressure drop to the operator
- Interlocks tying spray equipment and burners to fan operation
Keeping Discharge Away From Intakes
A common problem in growing plants is exhaust discharging close to a make-up air intake or a neighbor's rooftop unit. Solvent-laden air re-entering the building defeats the purpose. We review roof layouts in Atlanta and Savannah-area buildings for stack placement relative to intakes and prevailing airflow around the building.
Replacing Fans and Motors
Exhaust fans run every hour the booth runs, and bearings, belts and motors wear out. Replacement is an opportunity to correct undersized fans, add variable speed drives for energy savings and improve filter monitoring.
Planning a booth or oven project in Georgia
Crews mobilize from Houston; Georgia is roughly 700 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Georgia is concentrated around Atlanta, Savannah, Augusta, and Columbus. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive assembly and EV, aerospace, transportation equipment, and heavy machinery.
Hot, humid summers and mild winters put the emphasis on make-up air cooling or tempering, filter change schedules and keeping intake away from loading doors.
Frequently asked questions
Why is our booth not clearing overspray?
Low exhaust airflow is the usual cause: loaded filters, a worn fan belt, damaged duct or an undersized fan. Measuring airflow pinpoints it.
How high does a booth exhaust stack need to discharge?
Tall enough to discharge above the roofline and away from intakes, consistent with local requirements. Roof layout and surrounding equipment affect the answer.
Can a variable speed drive be added to our exhaust fan?
Often yes. Drives can reduce energy use and help maintain airflow as filters load.
How often should booth exhaust filters be changed?
When the manometer reading reaches the replacement point for the filters in use. Calendar schedules alone can miss heavy weeks.
Can you replace an exhaust fan without replacing the booth?
Yes. Fan and motor replacements are common and can correct original sizing problems.
