The pump unit assembly of a handheld compressed air sprayer consists of which components?

• A. A handle, tank cap, gasket, pump Rod, plunger cup and check valve
• B. A nozzle, trigger, hose, and battery
• C. A seal, filter, chamber, and gauge
• D. A wand, tip, container, and switch

Answer: (B)

In a handheld compressed air sprayer, the pump unit is the spray gun portion that actually delivers the spray. When the sprayer is battery-powered, this unit includes the nozzle, which sets the spray pattern and exit shape; the trigger, which starts and stops the flow; the hose, which carries liquid from the reservoir to the nozzle; and the battery, which powers the pump that creates the pressure. These parts work together to generate and control the spray from the device. Other components like the handle, tank cap, gasket, pump rod, plunger cup, and check valve belong to the reservoir or pump mechanics and aren’t part of the spray gun’s pumping unit itself.
