Crossdraft Booths for Wisconsin Shops Running Liquid Next to Powder
Plenty of Wisconsin finishing shops run powder as the main process and still need a booth for liquid coatings: specialty colors, touch-up, parts that cannot see oven temperature, or customer specs that call for wet paint. A crossdraft booth is often the simplest way to add that capability without disrupting the powder line.
Discuss your installationKeeping Liquid and Powder Apart
Powder overspray and wet paint overspray do not mix well, either in the air or in filters. The liquid booth needs its own exhaust, filters and stack, located so powder dust from the coating line does not get pulled through its intake doors. Physical separation and airflow direction are the main tools.
- Locate the liquid booth away from powder booth openings
- Give each booth its own exhaust path
- Keep liquid booth intake air clean
Using the Existing Oven
Shops often want liquid-coated parts to flash and then cure in the existing powder oven. That depends on the coating's requirements and on oven settings. Material flow between the liquid booth and the oven entrance should be short and clear, without crossing powder traffic.
Utilities for a Second Booth
Adding a liquid booth means more exhaust leaving the building and more replacement air needed. Existing make-up air may already be stretched by the powder line and oven. We review the plant's air balance and electrical capacity before adding the booth so the whole building still breathes properly.
Ongoing Care
Liquid booth filters and seals need different attention than powder recovery equipment. A short maintenance routine keeps the booth clean and avoids buildup in the exhaust chamber.
Planning a booth or oven project in Wisconsin
Crews mobilize from Houston; Wisconsin is roughly 1,000 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in Wisconsin is concentrated around Milwaukee, Madison, Green Bay, and Appleton. The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include heavy machinery and engines, paper products, food processing equipment, and metal fabrication.
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
Can we put a liquid booth in the same room as our powder line?
Often yes, with careful placement and separate exhaust. Keep powder dust away from the liquid booth intake.
Can liquid-painted parts go through our powder oven?
Sometimes. It depends on the coating's cure needs and the oven profile. Check with your coating supplier first.
Will adding a booth affect plant air?
Yes. It increases exhaust, so replacement air must be planned or the building goes negative.
Is crossdraft enough for touch-up and specialty coatings?
For most small and medium parts, yes. It gives a controlled, enclosed space with simple installation.
What should we gather before a visit?
Your plant layout with the powder line and oven, part sizes for liquid work, coating types and utility service information.
