The CP-109-LS-AS is the air stop version of the CP-109-LS combo nozzle, featuring a built-in Air Stop Check Valve for faster, more positive shut-off compared to standard check valves. The Air Stop system eliminates the need for a separate pinch valve, delivers complete shut-off within seconds with no leaks or drips, and allows field maintenance without tools — keeping workflow going. The poly body attaches to 3/4″ cam couplers and features a poly eight-orifice selector with sizes 2.5, 5, 7.5, 10, 15, 20, 24, and 30. Standard stainless steel deflector tips are 7.5, 18, and 35, though any available tip size can be used with any orifice.

The CP-109-LS-AS generates consistent large droplets with few driftable fines and has flood nozzle flow rates ranging from 0.43 to 6.71 GPM at 30–50 psi. Operating air pressure for the Air Stop system should be between 20–40 psi higher than liquid pressure. The system operates at lower air volume than traditional pinch valves, reducing wear and tear on the compressor. Works with 30″, 40″, and 60″ boom spacing. Simple conversion kits are available for operators already using other CP nozzles.

The CP-109-LS-AS is the premium low volume floater combo choice for operators who want the fastest possible shut-off and tool-free field maintenance. All parts are replaceable for long service life. Use the CP Quick Calc to find suggested orifice and tip settings for your target GPA.
