How To Choose Which Emitter or Dripper Is Right For Your Drip Irrigation System

Drip Irrigation Emitter/Dripper Comparison

There are many ways to apply water to plants with drip irrigation. The component at the end of the line that actually delivers water to the plant is called an emitter or dripper. Drip emitters may drip very slowly or output a steady flow of water. Some are staked and some stream water in "fingers" or a fine spray. Pressure-compensating drip emitters contain a rubber or silicone diaphragm that allow them to maintain the same output even if the water pressure fluctuates. Non-pressure-compensating drip emitters are less expensive but the flow will very with changes in elevation and pressure.

Pressure Compensating Emitters

Deliver the stated gph (gallons per hour) even if pressure range is 10- 40 psi
Works well with elevation changes
Self flushing to reduce clogging
- Operating Pressure Range: 10.2 - 58 psi
- Inlet Barb Size: 1/4"
- Outlet Barb Size: 1/8" - intended for 1/8" micro tubing or Netafim Superflex
- Shut-Off (Closing) Pressure: 1.7 psi (3.9' of Elevation)
