We've searched far and wide to come up with a rubber membrane diffuser that can generate a ton of air! What's even better is that this is a low psi design, which means your windmill or electric aerator doesn't have to struggle to open up the perforated slits like it would with some rubber membranes on the market.
This 9" membrane is used in the water treatment industry to really move the water through its precision perforated slits. Unit comes with a backflow valve and 1/2" fittings to plug into your 1/2" airline. Rated for up to 5 CFM and perfect for lakes or ponds, especially where you're only running one diffuser.
This diffuser can be placed into our Airstone Housing bucket which protects it from the mud and the muck on the bottom of your pond.
