A Public Health emergency response leader sets up a field hospital after flooding in Ubon Ratchathani — 800-1,200 patients and evacuees in canvas tents on bedding cots, with standing water around the perimeter. Mosquito populations explode within days, threatening a dengue outbreak layered over flood-related illness. The World Health Organization classifies mosquitoes as the deadliest animal on Earth — 725,000+ deaths annually. Thailand DDC reported 100,000+ dengue cases and ~100 deaths in 2025. Emergency response teams at a field hospital in Ubon Ratchathani chose AIROFOG AT35 as the primary defense.
Canvas tents over standing water become instant breeding habitat. Patients and evacuees often have weakened immunity; a dengue infection on top of post-flood illness can be fatal. Medical staff working 24-hour shifts in tents also suffer constant bites. Mosquito density peaks between 16:00 and 19:00 — the Aedes feeding window. People outdoors take 15-30 bites per hour. Skin-sensitive individuals develop rashes. Topical repellents are expensive and trigger allergies.
A news image of "mosquito-infested field hospital" damages public trust in the health system — something MoPH actively monitors. Management is responsible for the health and safety of those in care. Mosquitoes carry dengue, chikungunya, Zika, and lymphatic filariasis — real threats requiring real preparation.
Mosquito coils and hand sprayers have limits. Coils cover only the immediate ring. Hand sprayers wet only leaves the nozzle reaches, missing leaf undersides and crevices under bridges and flower beds. External pest-control vendors are expensive, visit monthly at best, and mosquitoes return within days.
The clean solution: own the equipment, train 1-2 designated operators, schedule weekly sprays, and use Department of Agriculture-registered chemicals at safe concentrations. AIROFOG AT35 meets the requirement.
AT35 is a 6.6 kg shoulder thermal fogger with a 5.6-liter tank, 25.5 kW pulse-jet engine, and 35 L/hr maximum output. A 0.5-50 micron droplet spectrum drifts 15 m horizontally and 8 m vertically, penetrating tree hollows and crevices where mosquitoes shelter.
Made in Taiwan by AIROFOG (ISO 9001, CE). Used by Thailand DDC, every provincial public health office, 5,000+ local government units, the Royal Thai Army, and major hospitals. WHD is the official Thai distributor with lifetime support.
Fog drifts 15 m horizontally; covers a 2-4 rai field hospital footprint in 20-30 minutes. Two sprays per month deliver complete protection.
Spray 1-2 hours before activity. Fog dissipates; residual chemistry protects 7-14 days. Emergency response teams spray around tents morning and evening for 24-hour coverage
Pull-cord start, single throttle valve. One-hour training. No engineering background required.
External vendor cost: 150,000-250,000 baht per incident. AT35 plus chemicals for a year: 50,000-60,000 baht. Payback in 6-12 months; 80-90% annual savings thereafter.
0.5-50 micron thermal fog penetrates tree hollows, bridge undersides, tent floors, flower beds — every refuge mosquitoes use. Conventional cold foggers cannot.
Use Department of Agriculture-registered chemicals (deltamethrin, permethrin, natural pyrethrum). Fog dissipates in 30-60 minutes.
304 stainless steel, ceramic nozzle, 600°C combustion chamber. One-year warranty. Bangkok parts inventory, 24-hour shipping.
Operates in humidity, drizzle, light wind, and tropical heat. Thermal fog rides air currents into damp foliage.
