Hunter pressure-compensating bubbler nozzles deliver a controlled, low-velocity flow of water directly to the root zone of trees, shrubs and raised planters, eliminating the soil erosion and water waste associated with conventional flood bubblers at variable pressures. The pressure-compensating diaphragm maintains a consistent output from 1.4 to 4.1 bar, ensuring each tree or shrub receives the same volume regardless of its position on the zone. Available in single-stream, multi-stream and flood configurations and in a range of flow rates from 0.9 to 7.6 l/min to match the water requirement of the plant.
