PFS CUSTOM SOLUTIONS — ZERO-EMISSION FLEET FINISHING
Specialized finishing enclosures and maintenance service bays engineered for hydrogen fuel cell electric buses, commercial transit fleets, and alternative-fuel vehicles. NFPA 33, NFPA 2, UL 508A, and CID2 classified location compliant.


Hydrogen fuel cell electric vehicles (FCEVs) and zero-emission transit buses require specialized maintenance and finishing environments. Because hydrogen gas is extremely buoyant and has a wide flammability range, conventional bus bays are inadequate for heavy maintenance, leak repair, or coating touch-ups.
PFS hydrogen bus finishing systems feature high-level exhaust extraction, continuous mechanical ventilation, explosion-proof CID2 electrical specifications, optional LEL sensor integration, and UL 508A certified control panels. Built in Santa Rosa, California and backed by 16+ years of heavy equipment manufacturing expertise.
Explore the core engineering and compliance specifications built into every PFS hydrogen and alternative-fuel fleet bay.
Engineered specifically for alternative-fuel and hydrogen fuel cell electric vehicle (FCEV) maintenance. Continuous high-volume mechanical ventilation prevents vapor accumulation, meeting NFPA 33 and NFPA 2 safety guidelines for hydrogen containment and gas dispersion.
Equipped with UL listed, spark-resistant tube axial exhaust fans. Continuous air movement draws hazardous gases and overspray away from technicians and work surfaces at required face velocity standards.
Class I Division 2 inside-access four-tube light fixtures. Sealed against vapor intrusion, fluorescent or LED tube compatible, providing shadow-free illumination across the entire bus chassis and roof maintenance zones.
PFS Core Control Panel — UL 508A certified with integrated gas detection interlocks, ventilation airflow monitoring, programmable cycle timers, and emergency purge modes.
Optional integrated RKI or Honeywell LEL gas sensors mounted at high-level ceiling zones where hydrogen naturally collects. Automatically triggers visual/audible alarms and high-speed purge ventilation upon vapor detection.
Designed for heavy transit buses, commuter coaches, hydrogen fuel cell trucks, and municipal fleet vehicles. Available in drive-through configurations or dead-end maintenance bays with service mezzanines.
Exhaust uses multi-stage arrestor media. Intake uses tacky-type primary filtration with optional blanket upgrades to maintain positive pressure and keep ambient facility dust out of sensitive finishing zones.
Heavy-gauge structural steel framework built for rugged commercial fleet maintenance depots. Designed to withstand rigorous daily transit operations while maintaining strict regulatory compliance.
Engineered, fabricated, and tested in Santa Rosa, CA. Ships nationally across the USA and Canada with complete engineering packages, PE stamps available, and turnkey installation support.

Hydrogen is very buoyant and flammable over a wide range of concentrations, so it collects at the ceiling. Bays need ceiling-level detection, ventilation and classified electrical designed around that behavior.
Spray finishing falls under NFPA 33, and hydrogen technologies fall under NFPA 2. Your local authority having jurisdiction makes the final call on the design.
Yes. Enclosures are sized for full-length transit and coach buses, with doors, platforms and lifts as required.
Yes. UL 508A controls can interlock with gas detection, ventilation and building management systems.
Pair your hydrogen bus finishing bay with complementary PFS equipment for a complete, regulation-compliant facility.
Full-enclosure booths for superior overspray containment and finish quality.
Tempered make-up air systems to replace exhausted air and maintain positive booth pressure.
Dedicated mixing rooms for safe paint preparation adjacent to your spray booth.
Blasting booths, reclaim blasting booths, and containerized blast booths.
