Techfilter Systems combine the Techfilter with a length of Bioline. The Techfilter is a disc filter with a chemical root intrusion preventer (trifluralin). The unique design characteristics of the Bioline emitter provides for an effective physical barrier against root intrusion without the addition of root inhibiting chemicals.

The Techfilter incorporates a replaceable filter element embedded with trifluralin. As water passes through this filter, a very low concentration of trifluralin (parts per billion) passes through the system. This technology provides very precise and even distribution of trifluralin throughout the piping network and provides added insurance. This approach to root intrusion prevention eliminates skin irritation from chemicals during installation, does not require that tubing be stored out of the sun, and is indefinitely renewable as needed.
