The Solo 423 is a backpack / knapsack motor mist blower that combines an engine-driven blower and spray system to atomize liquids and distribute them as fine mist.
It’s designed for use in agriculture (crop spraying, pest control), forestry, plantations, disinfection, greenhouse, vector control, etc.
Because it generates a high‐velocity air stream, the mist can reach into foliage, penetrate canopies, and cover difficult angles.
Typically used with chemicals like insecticides, fungicides, disinfectants, or fertilizers (in dilution).
