Root Prevention System

Insurance Against Root Intrusion

Our revolutionary Techfilter protects against roots invading the system. 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 (parts per billion) is transmitted throughout the system. This technology provides very precise and even distribution of trifluralin throughout the piping network and effectively inhibits root growth into the emitter outlets.

Exclusive Netafim USA Techfilter Limited Lifetime Extended Warranty

Every Netafim Techfilter carries a 2-Year-to-Lifetime Warranty. Proper use and timely replacement of the cartridge will keep the Lifetime Extended Warranty in force. Replaceable Techfilter disc cartridges come in conveniently sealed packages with gloves which have two benefits: extended shelf life and simple, clean replacement of the complete cartridge without having to touch the rings.
