A true story from a municipal health office: the night the fogger died mid-outbreak

At 5:30 a.m. on a Monday, Mr. Somchai, director of the public health and environment division at a central-region municipality, stood with his head in his hands outside the equipment store. An order from the district chief sat on his desk — 14 new dengue cases in two weeks, and residents from three villages had been calling to demand an urgent fogging team. But the seven-year-old fogger would not start: clogged carburetor, cracked nozzle, and no spare parts available because that model had long been discontinued.

This is nothing new for local public-health staff. Cheap foggers bought under tight budgets rarely survive more than a few rainy seasons. And exactly when they are needed most — during a dengue surge, a hand-foot-mouth outbreak at a child development center, or a fresh-market disinfection drive — they fail, leaving staff to absorb pressure from both the public and their superiors.

1. Public health: Mosquitoes multiply every day fogging is skipped. Dengue, chikungunya, and Zika spread fast in the wet season. Delayed control can lead to severe cases and deaths, especially among children and the elderly.

2. Budget: Hiring private contractors for emergency fogging costs far more than owning a reliable machine, and repeatedly repairing an old unit is money poured down the drain.

3. Reputation and trust: When residents ask for help and staff cannot respond, criticism appears instantly in village LINE groups and community Facebook pages, directly eroding confidence in local leadership.

SOLO PORT423: a German-made ULV fogger built for government missions

The SOLO PORT423 is an ultra-low-volume (ULV) backpack fogger, made in Germany, powered by modern SOLO engine technology with premium MAHLE components and a BING carburetor. Built for durability, sustained heavy use, and wide-area coverage — matching the real-world demands of municipalities that must protect an entire district.

1. Made in Germany with genuine MAHLE and BING parts — dependable engineering, not a cheap assembly.

2. Spray reach up to 12 meters — reaches shrubs, drains, under-house spaces, and the corners where mosquitoes breed.

3. Fine ULV droplets below 30 microns — the chemical stays airborne longer, contacts more mosquitoes, uses less chemical, and saves budget.

4. Large 12-liter chemical tank — longer continuous spraying, fewer refills, covers several villages in one run.

5. 72.3 cc two-stroke engine, 3 kW (4.1 hp) — power for heavy work, with a Nikasil-coated cylinder for heat resistance and long life.

6. Empty weight of just 11 kg — padded straps and 4-point vibration absorption let staff work all day without back strain.

7. Ergonomic one-hand lever — easy control of spray volume and start/stop, reducing fatigue during continuous use.

8. UV-resistant translucent tank — see the fluid level at all times without opening the cap, with material that will not crack in the sun.

9. Versatile across missions — mosquito fogging plus disinfection of fresh markets, schools, child centers, temples, bus terminals, and government buildings, all in one machine.

10. Local service and after-sales support in Thailand — confidence in spare parts, usage guidance, and procurement documentation.

Before SOLO PORT423: the old machine was hard to start, sprayed short, produced coarse droplets that fell to the ground, mosquitoes stayed thick, and residents complained that fogging felt like nothing happened. Dengue cases kept rising, and staff spent more time repairing than working.

After SOLO PORT423: first-pull starts, full-village coverage in less time, fine mist reaching every corner, a clear drop in mosquito numbers, fewer new case reports, and community feedback that turned into thanks.

"We switched our whole division to the SOLO PORT423. Now we get out on time every time, the machine never lets us down mid-job, it is easier on our backs, and most importantly, residents trust us again." — Municipal public-health officer (actual user)
