Netafim Techfilter protects against roots invading below ground irrigation systems.

Here’s how it works: Trifluralin is incorporated into the replaceable disc ring assemblies inside the filter housing. When water passes through the filter, a very low concentration of Trifluralin is transmitted. This technology provides very precise & even distribution of Trifluralin throughout the dripline system and effectively inhibits root growth into the dripper outlets

    • Replaceable Techfilter cartridge allows system to remain protected throughout its lifetime
    • Renewable warranty, activated when filter cartridges are installed and registered, gives the opportunity for a lifetime of protection
    • Delivers a low concentration of Trifluralin evenly to all drippers throughout the system
    • Sealed packaging dramatically extends shelf life and adds to filter replacement convenience
