Manual Disc Filters

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. Works well as a stand-alone unit or combined to form modular filter batteries. Available sizes 3/4” to 6” with mesh (micron) ranges from 40 to 200.

Features & Benefits

  • Highly effective multiple disc ring design captures and holds more debris.
  • Low friction loss keeps ysstem costs down
  • Greater holding capacity of the rings vs. screen filters mean less frequent cleaning.
  • Rings are easily removed for fast cleaning without the need for scrubbing.
  • Color-coded disc rings make identification of mesh rating fast and easy.


  • Wastewater
  • Reuse/recycle/reclaimed water
  • Spray tanks
  • Wherever very effective removal of debris is required
  • Works well as stand-alone units or combined to form filter batteries

Manual Disc Filters Operation

The Filtering Process

Grooved, compressed plastic disc rings produce a deep filtration process. As dirty water is pumped into the filter and pressure increases on the outside of the filter, the water pressure compresses the rings together tightly.

Grooves in the disc rings crisscross, forming a three dimensional network that traps particles. The number of crisscrossed intersection points on each groove varies, depending on filtration grade. The turbulence in the varying paths and the large number of intersections create an environment where particles are eventually trapped.

This design filters the dirty water thoroughly, not only on the outer surface of the cylindrical disc filter, but through the entire depth of every ring’s grooves. The result is a larger, more efficient filtering area (when compared to screen filters) with more debris being captured and cleaner water exiting from the filter.
