Spray Booths &
Finishing Booths
Paint, powder, blast, and fiberglass enclosures engineered to 100 FPM face velocity with full NFPA 33 and OSHA 29 CFR 1910.1000 compliance — and our pass-or-free guarantee on every installation.
Every booth we install comes with our pass-or-free guarantee — your inspection passes or we return and fix it at no charge.
Finishing Booths Built to Pass Inspection — Guaranteed.
Paint fumes, isocyanates, and solvent vapors are regulated by OSHA with zero tolerance. One failed fire marshal inspection or OSHA citation can mean immediate shutdown. Every booth we design and install is engineered to NFPA 33 requirements from the start — 100 FPM face velocity, explosion-proof electrical, fire suppression ready, and full documentation for your compliance file.
Paint & Clear Coat Finishing
Crossdraft, side-draft, and semi-downdraft configurations sized to your bay. Every liquid paint booth we build delivers 100 FPM face velocity across the full work envelope, explosion-proof LED lighting, and filtered exhaust meeting local air quality requirements.
- Crossdraft — standard, cost-effective
- Side-draft — even airflow across tall parts
- Semi-downdraft — floor-level exhaust
- Full downdraft — premium finish quality
- NFPA 33 spray finishing standard
- OSHA 29 CFR 1910.1000 air contaminants
- 100 FPM minimum face velocity
- Explosion-proof electrical throughout
Auto body and collision repair, custom fabrication paint lines, agricultural and heavy equipment refinishing, aerospace component finishing. Sized from single-bay walk-in to drive-through truck booths over 40 feet. Every installation includes full documentation for your fire marshal inspection.
Powder Recovery & Coating Enclosures
Powder coating booths with full recovery systems reclaim 30–50% of overspray — which pays for the upgrade quickly in powder savings alone. Engineered for color change efficiency, grounding compliance, and the specific airflow requirements of electrostatic application.
- Cartridge recovery filter system
- 30–50% powder reclaim rate
- Quick color-change design
- Grounding compliance built in
- Dedicated cartridge collector matched to booth CFM
- NFPA 660 combustible dust compliance
- Pulse-clean filters for continuous operation
- Explosion venting sized to powder KSt
Powder coating dust is combustible. Under NFPA 660 (effective January 1, 2026), your dust collector must be sized and protected for your specific powder’s explosion class. We conduct the dust hazard analysis and engineer the explosion protection as part of every powder booth installation — not as an afterthought.
Abrasive Blast & Surface Prep Enclosures
Blast booths for sand, steel shot, glass bead, and other abrasive media. Designed for complete containment, abrasive recovery, and dust collection that keeps your operators within OSHA silica exposure limits — without stopping production to clean.
- Abrasive recovery floor systems
- LED explosion-proof lighting
- Negative pressure containment
- Drive-in configurations available
- Cartridge or baghouse collector matched to CFM
- Silica dust OSHA PEL compliance
- Reverse-pulse filter cleaning
- High-efficiency media for fine abrasive dust
OSHA’s silica standard (29 CFR 1926.1153) sets an 8-hour TWA of 50 μg/m³ for respirable silica — 4× stricter than the previous limit. Blast booths without proper dust collection routinely expose operators to levels 10–100× the limit. Every booth we size includes capture velocity calculations verified against OSHA’s engineering control requirements.
Six Finishing Environments. One Standard: Pass Inspection.
Every booth type has different airflow, containment, and compliance requirements. Here’s what each one demands.
Liquid Paint Booths
Crossdraft, side-draft, semi-downdraft, and full downdraft configurations. 100 FPM face velocity, explosion-proof electrical, filtered exhaust.
Powder Coating Booths
Cartridge recovery systems reclaim 30–50% of overspray. Combustible powder requires NFPA 660 dust collector with explosion protection.
Blast Booths
Abrasive recovery, negative pressure containment, and dust collection sized for OSHA’s 50 μg/m³ silica PEL. Drive-in sizes available.
Fiberglass & Gelcoat
Styrene and resin fume capture with activated carbon filtration. Required for marine, RV, and composite manufacturing operations.
Truck & Heavy Equipment
Drive-through booths 40 feet and longer for fleet refinishing, agricultural equipment, and oversized fabrications. Engineered to the same 100 FPM standard.
Custom Enclosures
Any size, any process. If your operation doesn’t fit a standard configuration, we design to your bay dimensions and production requirements.
Common Questions About Finishing Booths
What NFPA standard applies to spray finishing booths?
NFPA 33 governs spray application using flammable or combustible materials. It sets requirements for ventilation (minimum 100 FPM face velocity), electrical equipment (explosion-proof in the spray zone), fire suppression, and construction. Powder coating operations that generate combustible dust also fall under NFPA 660, the unified combustible dust standard effective January 1, 2026. Every booth we install is engineered to meet both standards as applicable.
What is 100 FPM face velocity and why does it matter?
NFPA 33 requires a minimum of 100 feet per minute of air velocity across the entire face opening of the booth. This is what actually captures the flammable vapors and pulls them away from the operator’s breathing zone before they can accumulate to flammable concentrations. An underpowered booth that can’t maintain 100 FPM across the full work area fails NFPA 33 compliance regardless of everything else. We verify face velocity at every point in the work envelope during commissioning and provide written test results.
Does powder coating require explosion protection?
Yes. Powder coating dust is combustible — most coating powders have KSt values in the St 1 range (1–200 bar·m/s). Under NFPA 660, the dust collector on your powder booth requires a dust hazard analysis and explosion protection sized to your specific powder’s explosion class. This typically means explosion venting on the collector and isolation to prevent flame propagation back through the ductwork. We include the DHA and explosion protection engineering in every powder coating booth installation. Learn more about KSt values and explosion classes.
How much does a finishing booth cost?
Booth cost varies significantly by type, size, and configuration. Walk-in paint booths for auto body or small fabrication shops typically run $25,000–$75,000 installed. Powder coating booths with recovery systems range from $35,000–$100,000 depending on size and recovery efficiency. Drive-through truck and heavy equipment booths start around $80,000 and can exceed $200,000 for large custom configurations. Blast booths with abrasive recovery run $40,000–$150,000+. For a full project cost framework, see our 2026 system cost guide.
Can you serve facilities in California, Nevada, or Utah?
Yes. We install finishing booths across all five Southwest states — Arizona, California, Nevada, New Mexico, and Utah. California facilities face additional requirements from Cal/OSHA and local Air Quality Management Districts including SCAQMD and BAAQMD permitting for spray finishing operations. We design to all applicable state and local requirements in each service area.
