The Netafim Techfilter is designed for use with drip tube under lawns. It delivers a low concentration of Trifluralin to each dripper in the system to prevent root intrusion. Many people install drip irrigation systems under lawns without this protection and while the system may work for a little while eventually it will clog.
The roots under the lawn search for the water source and clog drippers. With the Techfilter, this won't happen. The Trifluralin deters the roots from entering the dripper and water continues to flow.
- Replaceable Techfilter allows simple renewal of protection over the years.
- Provides ultra efficient water filtration, far superior to screen type filters.
