An HSE manager at a pharmaceutical plant in Bang Pa-in Industrial Estate, Ayutthaya, oversees an 8-rai site with cleanroom production buildings, raw-material storage, and loading docks. GMP requires the perimeter to keep mosquitoes and insects away from production zones. Monsoon mosquitoes infiltrate through air intakes, threatening both GMP audits and product safety. 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. Pharmaceutical plants at Bang Pa-in Industrial Estate, Ayutthaya chose AIROFOG AT35 as the primary defense.
GMP audits by Thai FDA and international inspectors (PIC/S) check for insect traces around the perimeter. If mosquitoes are found in monitored zones, the plant can lose certification. 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.
Loading-dock and security staff who get bitten and develop dengue cause production-capacity losses. 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 5-10 rai plant 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. Pharmaceutical plants perimeter and yard spray before morning shift
Pull-cord start, single throttle valve. One-hour training. No engineering background required.
External vendor cost: 180,000-250,000 baht/year. 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.
