TSC Spray Booth Maintenance Guide 2025/2026

Summary: A practical maintenance guide for automotive spray paint booth owners who want reliable airflow, consistent finishes, and fewer breakdowns. Use the schedule below to keep your booth safe, compliant, and productive.

Safety note: Power down and lock out the booth before any service. Allow hot components to cool. Use PPE suitable for solvents and dust.

Why preventative maintenance matters

Proactive servicing protects staff, equipment, and finish quality. It also reduces unplanned downtime and helps with compliance and insurance requirements.

• Fire risk reduction: Remove overspray and dust from fans, plenums, and ducts. Replace exhaust filters before they load up.
• Worker health and safety: Maintain strong airflow to move fumes out of the breathing zone. Test interlocks and emergency stops.
• Finish quality: Replace inlet filters regularly to stop dust contaminating paintwork.
• Uptime and cost control: Spot worn belts, tired motors, and clogged filters early so you avoid expensive failures.
• Compliance and documentation: Maintain a log of inspections, filter changes, and services. This helps with audits and claims.

Key maintenance areas

Air filters intake and exhaust

Intake filters clean incoming air. Exhaust filters capture overspray. Keeping both in good condition preserves airflow, booth balance, and finish quality. Shop inlet filters | Shop exhaust filters

Fans, belts, and drives

Clean blades and housings to prevent imbalance. Inspect belt tension and wear. Replace belts at set intervals. Browse belts and misc parts.

Intake plenum, ducting, and stack

Keep louvers and screens clear. Schedule duct cleaning before residue becomes a restriction or a hazard. Confirm dampers move freely and seal properly.

Controls, interlocks, and safety systems

Check pressure gauges, airflow sensors, emergency stops, and door interlocks. Heated booths require burner service at regular intervals by a licensed technician.

Booth interior cleanliness

Overspray on walls, floors, and light glass will contaminate paint work and increase fire load. Shop cabin consumables.

Daily tasks

• Floor clean: Sweep or use an approved vacuum while ventilation is running to capture airborne dust.
• Surface wipe: Wipe walls, doors, and light glass with a mild detergent. Remove fresh overspray before it cures.
• Filter glance and gauge check: Inspect intake and exhaust media. Log pressure readings. Rising pressure signals loading.
• Fan sound and pull: Listen for unusual noise. Confirm strong exhaust pull. Investigate weak airflow immediately.
• Doors and seals: Clean jambs and seals so the doors close airtight. Shop door consumables.
• Panel status: Check indicators and alarms. Make sure the emergency stop is accessible and operational.

Weekly tasks

• Deep clean interior: Wash walls, floors, and doors. Rinse and dry to prevent residue and dust.
• Exhaust filter service: Inspect and replace when loaded. Shop exhaust filters.
• Fan and plenum clean: Open access panels. Wipe fan blades and housings. Tighten hardware as needed.
• Belt and moving parts: Check belt condition and tension. Replace belts if worn.
• Lighting: Clean light glass. Replace any dim or flickering tubes.
• Consumable stocktake: Confirm spares on hand. Filters. Belts. Coatings. Bulbs.

Monthly tasks

• Main filter changeout: Replace inlet filters and exhaust filters on a regular cycle.
• Fans and motors: Clean motor bodies. Check bearings. Inspect mounts.
• Air path health: Inspect duct interiors and clear screens. Exercise dampers.
• Safety systems: Test emergency stop and door interlocks. Inspect suppression nozzles.
• Interior reset: Clean or replace wall protection. Shop cabin consumables.

Annual tasks

• Professional service: Book a full inspection and service by a qualified spray booth technician.
• Airflow verification: Measure intake and exhaust velocity and pressure. Re balance if required.
• Duct and stack clean: Arrange a full clean of plenums and exhaust ducting.
• Preventative replacements: Replace worn seals or consumables. Shop door consumables.
• Electrical audit: Have a licensed electrician check control gear and relays.
• Burner service: Book a licensed gas technician to service burners.
• Full clean and repaint: Perform a top to bottom clean. Recoat walls for a bright reflective interior.

Conclusion and next steps

Consistent daily cleaning, weekly tune ups, monthly changeouts, and a yearly overhaul keep your booth safe, compliant, and profitable. Record each action in a simple log. Strong airflow and a clean interior will show up in every paint job.
