Netafim's Pulsar with StripNet™ Head is pressure compensated and distributes small amounts of water, multiple pulses per minute according to the flow rate, over a large wetted pattern. It ensures continuous irrigation over a broad range of pressures. StripNet head is available in three flow rates, 3.1, 4.0, and 5.3 GPH and is ideal for frost mitigation or cooling in vineyards.
- Pressure compensation delivers precise and equal amounts of water over a broad range of pressures.
- Unique self-compensating mechanism in the dripper makes it ideal for hillside applications or longer rows.
- Delivers multiple pulses per minute, according to the flow rate, ensuring continuous irrigation over a large area.
- Targeted application of water eliminates soil saturation or flooding even after many hours of irrigation.
- Retrofitting from an existing drip system is simple and quick.
- Flow rates match dripline flow rates.
- Frost mitigation for vineyards
- Cooling in vineyards
- Strip irrigation
- The pressure compensating dripper, inserted into the lateral line, allows water to enter.
- Water travels through the micro-tubing into the pulsar tube.
- An air bag inside the pulsar tube is compressed as water fills the tube.
- When the pressure inside the tube reaches the opening pressure of the check valve, it opens and an irrigation pulse starts.
- As the Pulsar irrigates, the pressure inside the tube decreases and when it reaches the closing level of the check valve, the irrigation pulse ends.
- When the check valve closes, the pressure inside the tube starts to build up again for the next irrigation pulse.

Typical Vineyard Installations
The most common Pulsar installations are described below and illustrated. Maximum recommended distance between the heads is 20' with a rectangular wetting pattern of 1.5'.
- The distributor pipe (lateral line) lies on the ground.
- The distributor pipe (lateral line) is attached by plastic bands or clips to the lower wire of the trellis system.
NOTE: If the distance between the poles along the trellis system is greater than 20', add metal or fiberglass rods in between to enable the installation of additional heads.
The most common Pulsar mounting options are described below and illustrated.
- Wooden Post: blue plastic clamp mounts to the wooden post, the Pulsar snaps into the clamp and a UV rated zip tie/stainless steel wire tie is used to secure the Pulsar to the post.
- Metal Stake: blue plastic clamp slides on to the top of the metal stake, the Pulsar snaps into the clamp and a UV rated zip tie/stainless steel wire is used to secure the Pulsar to the stake.
NOTE: Attach the Pulsar at a distance from the lateral that allows the micro-tubing to reach the lateral without tension.
