Which spray device uses air pressure to move liquid through an atomizing device?

• A. Compressed-air sprayer
• B. Carrier
• C. Cone-Spray nozzle
• D. Containment system

Answer: (A)

Using air pressure to move liquid through an atomizing device means the spray system relies on compressed air to push the liquid and break it into tiny droplets at the atomizer. The compressed-air sprayer does exactly this: liquid is drawn into a mixing area and forced through an atomizing head where the high‑velocity air shears the liquid into a fine spray. The air is part of the atomization process, not just a carrier. This differs from a cone-spray nozzle, which primarily uses the pressure of the liquid itself to force it through a precise orifice and produce a cone-shaped spray, with atomization driven by hydraulic pressure rather than air. A carrier is not a spray device, and a containment system is about preventing drift or spills, not atomizing liquid into spray. So the compressed-air sprayer is the device that uses air pressure to move liquid through an atomizing device.
