UniRam is the industry’s most advanced pressure compensating dripline. Its specially developed drippers operate with the poorest water quality, in the most difficult environments and irrigates the steepest terrains with the highest uniformity. UniRam is the most reliable dripline for surface and subsurface applications.

Industry’s Most Reliable Dripper

  • Inlet filtration area is thirteen times larger than the nearest competitor, maintaining a steady supply of clean water to the dripper.
  • Widest dripper flow path – Netafim’s patented TurboNet dripper design’s wide flow path allows large particles to pass through the dripper, eliminating dirt build-up.
  • Anti-siphon mechanism seals the dripper outlet at system shut-down, blocking dirt and debris from entering the dripline after irrigation.
  • This mechanism also provides a mechanical barrier to root intrusion and prevents excess soil moisture, especially after a heavy rain, from entering the dripline after irrigation.
  • Continuous self-cleaning, self-flushing diaphragm cleans debris throughout the entire irrigation cycle.

Pressure Compensating Benefits at the Lowest Operating Pressure

  • Pressure compensating drippers provide higher uniformity on steeper fields and longer runs.

Achieves Up to 15% Energy Savings

  • Add together the lowest operating pressure and reduced friction loss at each dripper (due to the dripper’s low profile design) equals the industry’s greatest energy savings.

Wide Range of Flow Rates to Match Soil Infiltration Rates

  • With UniRam’s wide range of flows, designers can better match the soil infiltration rates. This allows water and nutrients to be available to a larger volume of the crop’s root zone.

Product Advantages

Anti-Siphon Mechanism
Anti-vacuum mechanism prevents suction of dirt into the dripline, providing the critical protection needed against dripper plugging.

Wide Compensating Range
Wide Compensating range maintains a constant uniform flow – longer runs and steep terrains are irrigated with high uniformity.

Exclusive Non-Leakage (CNL) Mechanism – Optional
Prevents system drainage when pressure is turned off at the end of each irrigation cycle. Ensures uniform water distribution during pulse irrigation.

Widest Flow Path – Ultimate Clog Resistance
Operates in extremely poor water quality conditions – designed with two wide flow path allowing larger particles to pass through, preventing plugging.

  • For surface or Sub-surface applications

Root Intrusion Barrier
Prevents roots from penetrating the dripper’s mechanism. Ideal for Sub-surface irrigation.

Large Filtration Area
Entire base of the UniRam dripper is made of filter inlets – flushing large particles from the dripper, eliminating clogging and maintaining an essential supply of water for uninterrupted operation.

Made of chemical-resistant silicon.


  • For surface or Sub-surface applications
  • For Agriculture, Greenhouse & Nursery, Landscape and Wastewater
  • Ideal for high frequency irrigation in undulating terrains
  • For poor water quality conditions

UniRam Technical

Thirty-seven years of Netafim experience shows itself – UniRam is the most advanced technology available today. UniRam’s dripper design maximized uniformity, making it the ultimate solution for Sub-surface applications. This continuous flushing feature and wide flow path keep drippers flowing at optimal rates without clogging or interrupting operation.
