At 5:30 a.m., before the first train, Wut, head of maintenance at a metro station, looked over the platform that within hours would fill with tens of thousands of riders. Everyone would touch the same escalator rail, press the same lift button, grab the same pole in the same carriage.
In a season when flu and COVID return, a transit hub becomes the fastest place for respiratory germs to trade hands. One sick rider coughs into a hand and grabs a rail; the next hundred riders pick it up without knowing.
Wut's team wiped touchpoints with disinfectant cloths in rounds. But in rush hour, with thousands streaming through the gates each minute, wiping barely meant anything — surfaces were re-contaminated the instant a cloth left them.
What changed the game was disinfecting the whole station during the late-night closure with the AIROFOG U260 ULV sprayer, fogging platforms, ticket halls and carriages quickly and thoroughly.
Mass transit is a city's lifeline — and a highway for disease. Shared touchpoints like escalator rails, ticket buttons, door handles and carriage poles are touched hundreds of thousands of times a day; flu, COVID and RSV cling to them for hours.
In enclosed, air-conditioned, crowded spaces like carriages and underground halls, cough droplets circulate for a long time, raising infection risk many times above open areas.
When an outbreak gets linked to transit, public trust in the operator wobbles instantly. Some riders switch to private cars, worsening traffic and pollution — a chain reaction bigger than it first appears.
For public agencies and operators, showing tangible, standards-based disinfection is a social duty and a way to preserve the confidence of millions of riders.
The challenge: stations have a very short nightly closure. Every clean must finish before the first train of the morning, so the tools must be fast, thorough and reliable.
Wiping touchpoints by hand is a good measure, but can never keep pace with rush-hour crowds, and handles only surfaces — not the air in enclosed halls and carriages.
Closing a station for long deep cleans is impractical; it disrupts a whole city's travel. The tool must work fast in the limited late-night window.
The answer is ULV fogging that covers the full volume of platforms, halls and carriages in a short time, with few people, disinfecting both surfaces and air — ready to reopen by morning.
The AIROFOG U260 is a German-engineered ULV sprayer trusted by transit systems worldwide. Its 15-30 micron mist drifts across platforms and slips into every part of a carriage — rails, seats, even air vents.
At just 3.4 kg, one maintenance worker can carry it aboard and fog carriage by carriage. An 800-watt motor and 6-step nozzle handle both open halls and tight carriage spaces, finishing in time for the first morning train.
The AIROFOG U260 let us fog the whole platform and the carriages within the late-night closure. A small team can cover the entire station, and riders feel much more at ease seeing it.
— Head of station maintenance, a metro line
The AIROFOG U260 is a German-engineered Airofog ULV sprayer, tested and certified by leading institutes in Thailand and abroad — the Department of Medical Sciences, the Department of Health, and Mahidol University's Faculty of Medicine, plus international standards such as WHO, TÜV Rheinland and IPARC. That gives a station operations and maintenance team confidence that every pass follows real science, not just the feeling of clean.
Just as important, the machine works with a wide range of certified disinfectants, so the chemistry can be matched to the target pathogen of each site. Before-and-after surface sampling consistently confirms more than 99.99% reduction of viruses, bacteria and fungi.

Can it fog carriages with fabric seats?
The nozzle gives a fine, volume-controlled mist, so seats and surfaces are treated without soaking — best done during overnight stabling.
How long per carriage?
With high output and broad coverage, each carriage takes little time, suiting the late-night window.
What disinfectant suits transit?
Use certified disinfectants safe for riders after ventilation; our team will advise the formula.
Is one unit enough for a big station?
One unit moves between zones; refill the 5-litre tank and continue — ideal for continuous work.
Can I get planning advice?
Yes — contact our team for free help planning fogging cycles and disinfectant choice for transit.
