RAD850 Rubber Membrane Air Diffuser – 8" – 1/2" npt

SKU RAD850 Category



RAD850 Rubber Membrane Air Diffuser – 8″ – 1/2″ npt

  • These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and destratisfying applications
  • Unlike air stones these diffusers are easy to clean
  • In testing they produce a slightly larger air bubble than air stones which translates into less oxygen transfer into the water, so for fish holding tanks, raceways, fish production ponds, etc. we recommend air stones
  • Barbed inlets have multiple size barbs, simply cut to fit the size tubing you are using
  • An excellent choice for pond and water garden aeration since they actually produce more circulation and water movement
