Prep Station Installation in California
A prep station earns its floor space by keeping sanding dust, filler dust and primer overspray away from the paint booth. In California shops where every bay is spoken for, the station usually has to fit beside an existing booth, share a make-up air source, and still pull clean, even air across the vehicle or part. Double D installs and connects prep stations so the airflow, lighting, curtains and utilities work together instead of fighting the booth next door.
Discuss your installationWhy sanding dust ends up in the paint booth
Most contamination problems we are asked about start in prep, not in the booth. An open sanding area with no controlled airflow lets fine dust drift across the shop and get pulled into the booth intake every time the booth runs. A properly installed prep station captures that dust at the source, holds it in the floor or rear filters, and keeps the shop air cleaner for every other operation.
- Downdraft or semi-downdraft airflow pulls dust below the work zone
- Full-length curtains keep the work envelope defined between jobs
- Exhaust filters sized for sanding dust, not just paint arrestance
- Lighting placed to show surface defects before primer goes on
Fitting a station into a crowded shop floor
Collision and fleet shops rarely have an empty corner waiting for new equipment. We look at where vehicles enter and leave, how the station lines up with the booth door, and whether there is room for curtain travel and filter access on the back side. Ceiling height matters for overhead plenums and track-mounted curtains, and the exhaust route to the roof has to clear existing duct, sprinkler lines and structure.
Sharing air with the booth next door
When a prep station and a paint booth run at the same time, both are pulling air out of the building. If the make-up air was sized only for the booth, the shop goes negative, doors get hard to open and dust gets pulled in from wherever it can. We check the existing make-up air capacity, decide whether the station needs its own heated supply, and interlock fans so the building stays close to neutral when everything is running.
If primer will be sprayed in the station
Many shops want to prime in the prep station to free up booth time. That changes the equipment from a dust-control enclosure into a spray area, which affects fire protection, electrical classification of lights and outlets, and what your local fire marshal and insurer will expect. Decide this before the station is ordered so the controls, filters and suppression can be planned in from the start rather than added later.
Planning a booth or oven project in California
Crews mobilize from Houston; California is roughly 1,350 miles away, so equipment, panels and tooling are staged and shipped ahead of the install crew.
Manufacturing in California is concentrated around Los Angeles, San Francisco Bay Area, San Diego, and Inland Empire (Riverside and San Bernardino). The sectors most likely to be specifying spray booths, blast rooms, powder systems and cure ovens there include aerospace, electronics, food and beverage equipment, and metal fabrication.
Mild temperatures keep heating loads modest; local air-quality districts tend to drive permitting, so exhaust and VOC controls are planned early.
Frequently asked questions
Can a prep station be added next to our existing paint booth?
Usually yes, as long as there is floor space for the enclosure, curtain travel and rear filter access, and the building can handle the added exhaust. We review the booth layout, make-up air and roof route during the site visit.
Do we need a separate make-up air unit for the prep station?
It depends on how much air the station exhausts and how much spare capacity your current make-up air has. If both units will run together and the existing supply is already near its limit, a dedicated or upsized unit is usually the answer.
Can we spray primer in a prep station?
Some stations are built for it, but spraying turns the area into a spray zone with different fire protection and electrical requirements. Tell us early so the station is laid out and connected for that use.
What should we have ready before a site visit?
A floor plan or rough sketch with column locations, the booth model and make-up air details if known, available electrical service, gas service details if heat is planned, and a description of the largest vehicles or parts you will prep.
How often do prep station filters need changing?
It depends on how much sanding the shop does. A manometer or pressure gauge across the filters tells you when they are loading up, which is a better guide than the calendar.
