Manual Disc Filters are engineered for efficient operation year after year with practically no maintenance. Plastic rings stack together creating a cylindrical filter element. During filtration, the rings are compressed together effectively filtering the water and protecting the system from clogging. The water is then forced to flow through the grooves of the disc rings, where debris is trapped; releasing only clean water to the irrigation system. Works well as a stand-alone unit or combined to form modular filter batteries. How It Works As dirty water is pumped into the filter, and pressure increases, the water compresses the disc rings together tightly. The water is then forced to flow through the grooves of the disc rings, where debris is trapped, releasing only clean water to the irrigation system.
