  • Rubber Membrane Air Diffuser 

    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, 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
