Designed for reliable, low‑profile deep watering, the Hunter AFB Adjustable Flood Bubbler is a pressure‑compensating nozzle that delivers a consistent flood pattern for trees, planters and shrub beds. Built to maintain flow across a wide pressure range, the AFB ensures even root‑zone saturation without runoff.

  • Pressure‑compensating performance: Maintains consistent output across varying inlet pressures for uniform watering.
  • Flow range: Adjustable up to 2.0 GPM (7.6 L/min) for precise application to planted areas.
  • Thread & compatibility: 1/2" threaded connection for direct use on risers or Pro‑Spray bodies; installs quickly and stays low‑profile.
  • Operating range & durability: Effective across typical irrigation pressures (commonly specified 20–90 PSI) and includes a fine filter screen to reduce clogging.
  • Ideal uses: Tree wells, large planters, shrub borders and any area needing deep, low‑trajectory soaking.

Each AFB bubbler nozzle is sold in standard bag/carton quantities and is backed by Hunter’s documented reliability. Use the adjustable control to dial in the exact output your plants need, then rely on its pressure‑compensating design to keep that output steady as system conditions change. For detailed installation diagrams and performance charts, refer to the Hunter Pro‑Spray documentation linked on the product page.
