Outdoor Water Solutions Rubber Membrane Diffuser with Base - 9" Diffuser
We’ve searched far and wide to come up with a Rubber Membrane Diffuser with Base 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. The 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 also comes with a base that can be filled with sand or gravel, so it sinks to the bottom of your pond.
Features:
- Base can quickly be filled with sand or gravel to sink
- ½” fittings
- Rated up to 8.5 CFM
- Backflow valve to prevent water from entering the airline.
