Premature pressure-drop alarm (filters look clean)
Differential pressure alarm triggers but visual inspection shows filters are not loaded. Typically a sensor/instrument issue.
Severity: medium
Static buildup in dry climates (arid winter shops)
Static electricity attracting overspray and airborne particulate to substrate, causing inclusions. Worse in low-humidity climates and winter.
Severity: medium
Summer flash time too short (paint drying too fast)
Mid-coat solvent flashing off too quickly in hot ambient. Causes mottling, dry spray, and metallic-orientation defects.
Severity: medium
Solvent pop / pinholes in topcoat
Volcano-like blisters or pinholes in cured topcoat from trapped solvent escaping during bake. Bake-cycle or flash-time issue.
Severity: high
Edge mapping / repair telegraphing
Repair-edge or seam outline showing through topcoat. Body-repair + coating cure issue, not booth-mechanical.
Severity: medium
Filters loading too fast (premature pressure drop)
Intake or exhaust filters reaching replacement threshold sooner than expected. Common after paint-volume changes, coating switches, or shop-environment changes.
Severity: medium
Filters loading too slow (suspiciously long filter life)
Filters lasting noticeably longer than expected. Usually indicates bypass, wrong-grade filter, or sensor drift — not actual filter longevity.
Severity: medium
Uneven filter loading across the bank
Some panels load faster than neighbors. Indicates airflow imbalance, panel damage, or localized high-paint zones.
Severity: medium
Humid-day finish issues (orange peel, sag, slow flash)
Paint defects that appear or worsen on high-humidity days. Resolved by humidity conditioning + flash-time extension.
Severity: high
Cold-start burner trouble (winter mornings)
Burner fails to ignite or holds flame poorly during cold-start. Resolves once the booth warms up; recurs at next cold start.
Severity: medium
Condensation on booth interior walls
Visible moisture forming on the interior wall panels during or after bake cycles. Often during cool-down or high external humidity.
Severity: medium
Waterborne basecoat sag / runs
Waterborne basecoat sagging or running on vertical surfaces. Tied to airflow velocity, humidity, and blower angle in modern waterborne workflows.
Severity: high
Fish-eye contamination on topcoat
Crater-like defects with raised edges from surface contamination (silicone, oil, water). Surface preparation + compressed-air-system issue.
Severity: high
Burner will not reach bake temperature
Burner runs but booth cannot hit target bake temp during cure cycle. Mostly mechanical/control causes.
Severity: high
Burner short-cycling during bake
Burner cycling on and off at short intervals during bake instead of holding a steady mid-fire output. Hits target then drops, repeating.
Severity: medium
Uneven cure zones (hot/cold spots in booth)
Bake cycle delivers different temperatures across the work zone. Some panels over-cure, others under-cure. Burner alignment or airflow imbalance.
Severity: medium
NESHAP differential-pressure alarm on filter bank
EPA NESHAP 6H differential-pressure alarm triggered. Filter efficiency documentation + immediate replacement may be required to maintain compliance.
Severity: high
Aerospace stage-3 pocket filter loading
Stage-3 NESHAP pocket filter loading faster than expected. Indicates upstream stage failure, volume increase, or chromate-heavy work.
Severity: high
OSHA spray-finishing documentation gap
OSHA 1910.107 + NESHAP 6H expect filter-change log, painter training certification, and differential-pressure records. Missing records = compliance gap.
Severity: high
Show your answers
Is the problem a visible defect in the paint finish — dust nibs, orange peel, fisheyes, runs, or other surface defects?
→ No
Does the booth refuse to start, or shut itself down on its own during operation?
→ No
Is overspray clearly escaping the booth into the surrounding shop area?
→ Yes
Is the booth's pressure reading abnormal — manometer reading too high or too low, or staff notice the booth is pushing/pulling differently than normal?
→ Yes
Is the HMI or booth controls displaying a specific fault code or alarm (VFD fault, gas pressure, flame failure, intake motor feedback, filter pressure)?
→ Yes
