Rubber Membrane Air Diffusers

Rubber Membrane Air Diffusers

• These Rubber Membrane Air Diffusers are incredibly strong and are ideal for pond aeration, circulation, and destratisfying applications
  

  • Unlike air stones, these Rubber Membrane Air Diffusers are easy to clean
  • In testing Rubber Membrane Air Diffusers produce a slightly larger air bubble than air stones which translates into less oxygen transfer into the water, so for fish holding tanks, raceways, and fish production ponds, 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
  • New 6" weighted diffuser available, part #RAD650W
