How a paint booth works
The systems behind a clean, fast finish.
A plain-English guide to the parts of a spray booth — airflow, filtration, heat, and controls — and why keeping them in spec protects your finishes and your throughput.
What we do
The parts of a spray booth.
Every booth heats, moves, and filters air the same way in principle. Understanding the pieces makes it easier to spot trouble early — and to describe it when you call for service.
Key components
Air make-up unit (AMU)
Pulls in outside air, heats it, and pushes it through the booth — the heart of airflow and cure.
Intake & ceiling filters
Clean the incoming air so dust and overspray stay out of your finish.
Exhaust filters
Capture overspray on the way out; as they load, airflow drops.
Burner & heat
Brings air to spray and bake temperature so paint flows and cures.
Dampers & recirculation
Switch the booth between spray and bake and control fresh vs. recirculated air.
Controls & manometer
Run the sequence and show static pressure — your booth's fuel gauge for filter health.

Questions & answers
Booth basics
What is booth 'airflow balance'?
The difference between air pushed in and pulled out. A slight positive keeps dirt out; negative pulls it in. See our maintenance service.
What does the manometer tell me?
Static pressure across your filters — a low reading is fresh filters, a high reading means it's time to change them.
Why does my booth need an AMU?
It supplies the clean, heated air that carries overspray away and cures your coating. Most airflow and heat problems trace back to it.
