Reviewed by: KrishiGears Product Team | Last updated: July 1, 2026 | Verification note: This page explains selection logic only. Confirm the official manual, chemical label and permitted use before buying or operating.
Quick answer
Thermal foggers create visible fog using heat and should be used only where the environment and chemical allow it. ULV foggers create very fine droplets without the same heat process and are often preferred for controlled enclosed or indoor-style applications.
Decision table
| Question | Thermal fogger | ULV fogger |
|---|---|---|
| Fog style | Visible heated fog. | Ultra-low-volume fine droplets. |
| Safety focus | Heat, fuel, ventilation, PPE and chemical compatibility. | Droplet control, PPE, ventilation and electrical/battery safety. |
| Before buying | Check fuel type, approved chemicals and service support. | Check droplet adjustment, tank, motor, power source and support. |
Buying advice
The safer choice depends on environment, target area, chemical label and operator training. Do not buy based only on fog visibility; effective and compliant application matters more.
