Open Face Booths for Wisconsin Job Shops and School Fabrication Labs
For a small fabrication shop or a school metal lab in Wisconsin, the first spray booth is usually an open face unit. It puts a defined, exhausted spray area against a wall, takes little floor space, and installs without doors, pits or a dedicated air make-up unit tied to the booth. What it does need is a smart location and a plan for the air it removes from the room.
Discuss your installationPicking the Wall
Open face booths usually back up to an exterior wall so the exhaust duct has a short run out of the building. Before choosing that wall, look at what is in front of it. Welding, grinding and saw cutting create the dust and spatter that ruin finishes, and the booth will pull that air straight across the work. A spot near the exit door for finished parts, away from the weld bays, usually works best.
- Short exhaust path to an exterior wall or roof
- Distance from welding and grinding
- Room to stage wet parts after spraying
- Clear access for carts or hand carry
Sizing for the Work You Actually Do
A job shop painting brackets, frames and small weldments rarely needs a huge booth. Oversizing the opening means more exhaust air, bigger fans and more heat leaving the building for no benefit. Size for the parts that make up most of your work, and handle the occasional big piece another way. For a school lab, booth size also depends on how many students work at once and how the instructor supervises them.
What Goes Into the Install
The booth panels, rear filter bank, fan and exhaust duct go in first, followed by lighting and electrical connections and fire protection coordination with that contractor. Replacement air for the room is the item most often overlooked. Even a modest booth can pull enough air to make doors hard to open and draw cold air in through gaps, so plan where that air will come from before startup.
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
Is an open face booth a good first booth for a small shop?
For many small fabricators, yes. It installs simply, takes modest floor space and gives a defined spray area with proper exhaust.
Can a school use an open face booth for student projects?
Yes. Many programs use one for metal and wood projects. Layout should give the instructor a clear view of students spraying.
Where should the booth go in the shop?
Near an exterior wall for a short exhaust run, away from welding and grinding, with room to set wet parts afterward.
Do we need an air make-up unit?
The room needs replacement air for what the booth exhausts. That might come from an air make-up unit, existing HVAC capacity or another planned source.
How often do the rear filters need changing?
When the pressure gauge across them shows the drop set by the filter maker. Spray volume determines how often that is.
Can the booth be moved later?
Yes. Open face booths are among the simplest to relocate. The exhaust duct and electrical connections are redone at the new spot.
