Exhaust Fans and Duct Sizing for Large Indiana Booths
A booth big enough for a trailer or a piece of heavy equipment moves a lot of air, and the exhaust system has to handle it without excessive noise or energy use. Indiana plants with large booths often need multiple fans, large duct and careful roof planning. Double D installs exhaust systems for large booths and connects them to make-up air and controls.
Discuss your installationOne large fan or several
Large booths may use a single big fan or multiple smaller fans. Multiple fans add redundancy and can be staged; one large fan has fewer parts. Roof structure, duct layout and controls guide the choice.
Duct sizing
Duct must be large enough to keep velocity and pressure losses reasonable. Undersized duct makes fans work harder and noisier.
- Duct sized for design airflow
- Smooth transitions and turns
- Sealed joints
- Cleanout access along runs
Roof and structure
Large fans and stacks add weight and wind load. Roof structure, curbs and supports need to be checked.
Balancing with make-up air
Large exhaust must be matched by make-up air. Exhaust and supply are interlocked and balanced.
Planning a booth or oven project in Indiana
Crews mobilize from Houston; Indiana is roughly 850 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Indiana is concentrated around Indianapolis, Fort Wayne, Evansville, and South Bend. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include automotive and powertrain, RV and trailer manufacturing, steel, and aerospace components.
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
How many fans does a large booth need?
It depends on airflow, duct layout and roof structure.
Why is our exhaust fan so loud?
Undersized duct, poor transitions or fan selection can increase noise.
Do large fans need roof reinforcement?
Sometimes. A structural check is recommended.
Can fans be staged?
Yes, with controls, which can help during cure or idle modes.
What information helps plan exhaust?
Booth size, design airflow, roof structure and coatings.
