AGF Sand Media Filters Technical

Description of System Operation


Unfiltered water enters via the inlet manifold. During filtration the inlet ports are open and water flows from the top to the bottom across the sand layer. The filtered water exits the system through the outlet manifold.


During backflush the inlet port closes and the backflush port opens which reverses the flow of water in the filter. Clean water from the other filters flows into the filter from the bottom lifting the sand media and freeing the accumulated debris. Debris flushes out the top of the filter through the backflush manifold.


  • Maximum Flow Rates:
  • Good Quality Water - 25 GPM/sq. ft.
  • Dirty Water - 20 GPM/sq. ft.
  • Minimum Filtration Pressure: 15 psi
  • Minimum Backflush Pressure: 30 psi
  • Maximum Operating Pressure: 85 psi
  • Sand Requirement: 1,300 lbs. per 48" Tank
  • Manifolds: Polypropylene
  • Leg Height: Adjustable
  • Backflush Valve: 4" Plastic Grooved Valve

The use of gravel and/or media not recommended by Netafim USA will void the warranty. Tanks must be filled with water prior to adding media. Failure to do so could damage the internal components and void the warranty.
