Woodpecker PC CNL Dripper

Woodpecker PC CNL Dripper


An on-line pressure conpensating (PC) dripper with a non-leakage (CNL) function for pulse irrigation in greenhouses, nurseries, citrus, orchards and deciduous trees.


  • Recommended filtration: 130 micron.
  • TurboNet™ labyrinth with large water passage.
  • To be inserted into heavy-walled PE pipe (0.9 to 1.2 mm).
  • Injected dripper, very low CV.
  • UV resistant. Resistant to standard nutrients used in agricultural.
  • PC on-line drippers meet ISO 9261 Standards with production certified by the Israel Standards Institute (SII).
PC CNL Dripper Flow rate (litres per hour) Colour of top Min pressure Max pressure Closing pressure
WPC CNL Low 2.0, 4.0 and 8.5 Brown 10 m 40 m 1.5 m
WPC CNL High 3.0, 6.9 and 12.0 Black 14 m 40 m 3.0 m


Features and Benefits:

  • Pressure compensated: Precise and equal amounts of water are delivered over a broad pressure range. 100% uniformity of water and nutrient distribution along the laterals.
  • PC-CNL Low and PC-CNL High with anti-drain. The CNL function eliminates drainage and refill effect and improves efficiency in pulse irrigation. The dripper closes below two pressures: CNL Low closes ≤ 1.5 m, CNL High closes ≤ 3.0 m.
  • Continuously self flushing: Flushes debris as it is detected, throughout operation, not just at the beginning or end of a cycle, ensuring uninterrupted dripper operation.
  • TurboNet™ labyrinth assures wide water passages, large deep and wide cross section improves clogging resistance. Widest water passages within the dripper.
  • Dripper can be positioned exactly where required.
  • Number of drippers can be increased so as to increase water quantity supply aimed at meeting tree growth rate requirement.
  • Allows the installation of "spider assembly", splitting the drip supply into a number of drip outlets.
