Which statement best describes Turbines or Mist Blowers?

• A. A sprayer where insecticide is delivered by a hydraulic pump into a high-velocity column of air produced by a turbine.
• B. A sprayer that uses a brush to scrub insecticide onto surfaces.
• C. A sprayer that disperses liquid through a nozzle at low pressure.
• D. A sprayer that relies on gravity feed for distribution.

Answer: (A)

Turbines or Mist Blowers work by atomizing insecticide into a fine mist using a high-velocity airstream produced by a turbine. The liquid is pumped under pressure through a hydraulic system and into that air stream, creating droplets small enough to be carried through the air for broad outdoor coverage, which is especially useful for mosquito control. This air-assisted spraying distinguishes them from other methods: brushing with a brush isn’t a sprayer; a low-pressure nozzle describes a simple spray without the strong air stream; and gravity feed distributes liquid without pressurized air or turbine-driven atomization.
