Hunter Industries AFB Adjustable Bubbler 0-2.0 Gpm

Product Description

The HUNTER INDUSTRIES AFB is a pressure-compensating adjustable bubbler designed for low-volume drip and flood irrigation applications. It delivers a flow rate adjustable from 0 to 2.0 gallons per minute (GPM), making it suitable for tree rings, shrub beds, and planters where controlled water delivery is critical. The 1/2 inch female iron pipe thread (FIPT) inlet allows direct installation onto standard irrigation risers or distribution manifolds. Irrigation technicians and landscape professionals install this type of device where uniform output is needed regardless of system pressure fluctuations.

The AFB bubbler is used in residential and commercial landscape irrigation systems, typically in drip or low-volume zones. It is well suited for applications requiring precise water placement at the root zone, including ornamental beds, raised planters, and individual tree basins. The adjustable flow design allows field technicians to dial in the output to match the water requirements of specific plantings without swapping emitters.

Key Features

• Adjustable flow rate from 0 to 2.0 GPM for flexible field configuration
• Pressure-compensating design maintains consistent output across varying system pressures
• 1/2 inch FIPT connection for compatibility with standard irrigation risers and fittings
• Compact, lightweight construction at 0.02 pounds for easy handling and installation
• Suitable for low-volume drip and flood irrigation zones

Compatibility

Designed as an OEM-style replacement or upgrade bubbler for standard 1/2 inch FIPT irrigation riser assemblies used in low-volume landscape irrigation systems.

Installation Notes

Installation is performed by licensed irrigators or landscape irrigation technicians. Shut off system pressure at the zone valve before threading the AFB onto the riser. Use Teflon tape or pipe thread sealant on the FIPT connection to ensure a leak-free seal. Do not overtighten the fitting, as this can damage the plastic threads.
