Netafim Five-Filter High Flow Disc Filter Battery
Big operations pumping from reservoirs and canals need filtration that matches their pumps. This Netafim battery puts five 3 inch filters on one manifold for that scale. Its flow range runs from 350 to 750 gallons per minute. Every filter carries red 120 mesh discs rated at 130 microns. Dirt lodges deep in the grooved disc stacks, which gives long runs between flushes. With five filters, four stay online during each cleaning step. That keeps pressure and flow steady across the irrigation system. On good water, Netafim allows up to 800 GPM at this mesh. Poor surface water with heavy algae growth supports about 525 GPM. Sand above 3 ppm calls for a hydrocyclone upstream. The battery weighs about 467 pounds and runs roughly 52 1/4 inches along the manifold. It ships assembled and tested with 6 inch grooved connections.
Filtering Reservoir Water at 750 GPM
Reservoir water usually carries algae, plant debris and fine silt that build up fast at high flow. The controller flushes one filter at a time using clean water from the other four. Wire the 24 VAC solenoids to an AC backflush controller, sold separately. A full five-filter cycle uses about 117 gallons of water. Each filter needs 70 GPM and 30 psi downstream during its flush. Start with a 20 second flush and a 10 second dwell between filters. Trigger flushes on a 5 psi rise in pressure difference or every 4 to 8 hours. Operate between 20 and 90 psi, with water at 158 °F or cooler. Size the drain line for the flush volume and keep the run short. Flush the main line through the inlet blind flange before first startup. Check the gauge weekly and clean discs by hand if it stays high after flushing.
