Brand: Hunter Industries SKU: AFB Product Overview The Hunter AFB adjustable flood bubbler is a pressure-compensating irrigation outlet designed for deep watering around trees, shrubs, and planted areas. It installs on a 1/2-inch threaded riser and applies water close to the plant’s root zone rather than spraying it across a wide landscape area. This concentrated application can be useful in tree basins, shrub beds, and other locations where controlled flooding is preferred over a conventional spray pattern. An integrated adjustment screw changes the discharge from a low trickle to a broader umbrella-style flood pattern, allowing the installer to match the output to the basin size, soil intake rate, and watering requirement. The adjustable flow is rated up to approximately 2.0 GPM. Pressure-compensating operation helps maintain more consistent output as pressure changes within the normal operating range of the irrigation zone. Key Features Adjustable trickle-to-umbrella flood pattern Pressure-compensating operation Maximum flow of approximately 2.0 GPM 1/2-inch threaded inlet Integrated flow and pattern adjustment screw Designed for concentrated root-zone watering Common Uses Tree wells and watering basins Shrub and landscape planting beds Deep watering around established plants Replacing a compatible adjustable flood bubbler Compatibility and Use Notes Install on a compatible 1/2-inch threaded riser or fitting. Actual flow and coverage depend on operating pressure, adjustment setting, installation height, basin shape, and soil conditions. Set the flow low enough to prevent runoff and erosion, and group the bubbler with irrigation outlets that have compatible precipitation and run-time requirements. Why Buy from Big Frog Supply?
