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

Netafim Two-Filter Disc Filter Battery for Drip Systems

Drip and micro irrigation fail fast when algae, silt and organic debris reach the emitters. This Netafim disc filter battery stops that material at the head of the system with two filters on one manifold. Each filter holds a stack of red 120 mesh discs rated at 130 microns. Water passes through the full depth of the grooved rings, not just their outer surface. That depth filtration traps more dirt before the filter needs cleaning. The battery covers a flow range of 50 to 160 gallons per minute. Poor water lowers the 120 mesh ceiling to about 120 GPM, so size the station to the source. It suits reservoirs, canals, rivers and well water carrying light sand under 3 ppm. The manifold, filter bodies, covers and discs are polypropylene, with a nylon spine and EPDM seals. Those materials resist rust and corrosion from fertilizers and weather. The unit arrives factory assembled and tested, weighing about 174 pounds. Its inlet and outlet are 4 inch grooved connections.

Setting Up Automatic Backflush on Two Filters

Backflushing is triggered by time or by the pressure difference across the filters. The controller then signals each 24 VAC solenoid in turn. One filter switches to flush mode while the other keeps supplying clean water to the system. Filtered water from the outlet manifold spins the loosened discs and carries debris out the drain. Each full cycle uses about 24 gallons of water. Keep at least 30 psi downstream during backflush and at least 35 GPM per filter. Run the system between 20 and 90 psi in normal service. Start with a 20 second flush and a 10 second dwell between filters. Many sites settle on a flush every 4 to 8 hours, adjusted to the water. Set the differential switch to trigger 5 psi above the clean reading. Run 2 inch PVC from the drain manifold, stepping up to 3 inch beyond 50 feet. The backflush controller is sold separately, so match it to the AC solenoids before startup. Check weekly that the pressure gauge returns to 0 to 2 psi after a flush.
