EasyPro Rubber Membrane Air Diffusers

This item is eligible for FREE shipping on orders over $200


  • 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
