Netafim 3 Inch Disc Filter Battery with DC Solenoids
Large field irrigation systems often draw from canals and rivers far from any power line. This Netafim battery brings 3 inch filtration to those sites with DC solenoids on all three valves. Each filter holds red 120 mesh discs that catch particles down to 130 microns. The discs trap debris through their full depth, so each flush clears a large load at once. Netafim rates the station from 150 to 450 gallons per minute. Very poor water such as muddy canals should stay near 210 GPM at this mesh. Average sources like clean ponds allow about 450 GPM. A hydrocyclone ahead of the filters handles sand above 3 ppm. Polypropylene bodies and manifolds will not corrode under fertilizer injection. The inlet and outlet use 6 inch grooved couplings. The assembled station weighs about 352 pounds.
Field Irrigation Setup with DC Control
Pair the DC solenoids with a matching DC backflush controller, which is sold separately. A solar panel or deep-cycle battery can supply the controller at the pump. Wire each solenoid to its own terminal, with one common lead shared by all. Use 16 gauge wire or heavier inside half-inch conduit. During a flush, one filter reverses while the other two keep the field supplied. A complete three-filter cycle sends about 70 gallons to the drain. Each filter needs 70 GPM of flow and 30 psi downstream while flushing. Normal operation runs from 20 to 90 psi. Begin with a 20 second flush and a 10 second dwell. Trigger flushes on a 5 psi rise in differential or every 4 to 8 hours. Use the manual override lever to test every valve during startup. Inspect discs and seals before each irrigation season.
