D5 is the multi-seasonal dripline with flat dripper ideal for orchards and perennial crops. The reduced size of the wall-welded drippers allows for reduced pressure losses, thus improving the supply uniformity. The design of the labyrinth reduces pressure sensitivity increasing the self-cleaning effect. The special positioning of the filter facing towards the center of the pipe makes water access the labyrinth far away from the stagnation areas. The wide range of the available hourly flow rates makes it suitable for all crops and under all conditions. Its low CV and its “x” and “k” values in the flow equation allow to reach long lengths with high uniformity. D5 dripline is available in 16 mm and 20 mm diameters, hole spacing from 10 cm. Available wall thickness: 24 mil and 35 mil.
