The unique design of the Netafimâ„¢ Techflow Emitters regulates flow and provides continuous self-cleaning action during operation. These emitters have a 2.2 PSI internal check valve that helps prevent low emitter drainage holding back up to a 5 foot column of water. The anti-siphon operation prevents contaminants from being drawn into the emitter. The Techflow Emitters are pressure compensating and deliver the same flow from 14.5 to 58 PSI.
Recommended minimum filtration of 120 mesh. Pair the Techflow Emitters with the 36 inch or 48 inch 2-way (#Q102463 / #Q102464) or 4-way (#Q112852 / #Q112853) Dripper Stake Assemblies.
