Features

• Featuring an innovative turbulent flow path and
chemically inert self-flushing silicon diaphragm
• Available in 1.6, 2.0, 2.4 and 4.0 Lph flow rates Innovative turbulent flow path
• Wide pressure regulating range from 100 kPa to 400 kPa with two directly opposed
• Turbulent flow path ensures there is no flow spike or Pressure compensating outlets to reduce risk of exit
prolonged flushing mode to deliver a regulated hole clogging.
• Two outlet holes and large exit chamber reduces risk of rate of water at varying
exit hole clogging pressures.
• Tubing sizes of 16, and 20 mm OD
• Durable, tough wall thickness of at least 1 mm Self-flushing diaphragm flushes in three stages, being start-

• Available in factory spaced intervals or custom made to flushing occurs where there is low pressure on the diaphragm
your spacing requirements and it is relaxed allowing particles to be passed out through the
emitter.

As the dripper begins to clog
there is a reduction of flow, and
pressure on both sides of the
diaphragm begins to equalise.
The diaphragm returns to its
relaxed position and particles
are flushed out. The dripper then
returns to normal performance
