Balancing Shared Booth Exhaust in Michigan Shops
When booths and prep stations share exhaust fans or duct, one area can rob airflow from another. Michigan collision shops and Detroit-area plants with multiple booths and prep stations need exhaust balanced so each area gets its design airflow. Double D balances booth exhaust systems and corrects the problems behind uneven airflow.
Discuss your installationWhy shared exhaust drifts
Filters load at different rates, dampers get bumped and duct runs differ in length. Over time, the area closest to the fan gets more air and distant areas get less.
Measuring each area
Airflow measurements at each booth and prep station show where the system stands.
- Face velocity or airflow at each area
- Static pressure at key points
- Filter pressure drop
- Fan speed and amperage
Dampers and adjustments
Balancing dampers are set, marked and locked. Filter changes and fan adjustments bring each area back to design airflow.
Keeping balance
Filter gauges at each area, regular checks and a record of damper positions keep the system from drifting again.
Planning a booth or oven project in Michigan
Crews mobilize from Houston; Michigan is roughly 1,100 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Michigan is concentrated around Detroit, Grand Rapids, Lansing, and Flint. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive assembly and suppliers, office furniture, tool and die, and EV batteries.
Cold winters mean make-up air heaters are sized for sub-freezing intake, and booth or oven placement has to account for frost lines, snow loads on roof penetrations and winter slab work.
Frequently asked questions
Why does one booth pull weaker than others?
Loaded filters, damper position or duct layout are common causes.
How often should exhaust be rebalanced?
After changes to equipment or filters, or when airflow complaints appear.
Can shared exhaust work well?
Yes, with good design, balancing and filter monitoring.
Should each booth have its own fan?
Separate fans simplify balance; shared systems can work when designed and maintained well.
What should we record after balancing?
Damper positions, airflow readings and filter pressure.
