Netafim 2 in LP Disc-Kleen Filter Battery, 3 Filters, 120 Mesh, 24 VAC Solenoids

Three-Filter Netafim Disc Filtration System

Greenhouse ranges and nursery blocks that pull from ponds or canals need filtration that keeps up without constant attention. This three-filter Netafim battery is sized for that middle ground. Its flow range runs from 100 to 240 gallons per minute. Each 2 inch filter carries a stack of red 120 mesh discs rated at 130 microns. Dirt lodges in the grooves throughout the disc stack instead of blinding a thin screen. With three filters, two stay online while the third backflushes. That keeps downstream pressure steadier during the cleaning cycle. Netafim allows about 225 GPM at 120 mesh on average water, such as clean ponds and canals. Poor sources with heavy algae growth lower that figure to about 180 GPM. A hydrocyclone ahead of the filters handles sand loads above 3 ppm. The polypropylene and nylon build stands up to fertilizer and acid injection. This disc filtration system weighs about 220 pounds and ships assembled and tested.

Running a Three-Filter Irrigation Filter Station

Wire the three 24 VAC solenoids to an AC backflush controller, sold separately. A differential pressure switch tells the controller when the discs are loading up. Set it to start a flush 5 psi above the clean pressure difference. A timer setting backs that up, with many sites flushing every 4 to 8 hours. Start each filter at a 20 second flush with a 10 second pause between filters. A full cycle across all three filters sends about 36 gallons to the drain. Keep 30 psi downstream and 35 GPM per filter available during the flush. Route the drain through PVC no smaller than 2 inches, and go larger past 50 feet. Flush the main line through the inlet blind flange before the first startup. Bring pressure up slowly, then run a manual flush to confirm each valve works. Check the gauge weekly and clean discs by hand if it stays above 2 psi after flushing.
