Rotary Drum Filters

Rotary drum filters (RDFs) are the gold standard in mechanical pond pre-filtration. A rotating micro-screen — typically 60–200 micron — automatically strains solid waste from your pond water and flushes it to waste, so solids never break down inside your system. Self-cleaning and low-maintenance, RDFs are built for heavy koi loads and the kind of pristine, glass-clear water serious keepers expect.
