Rubber Membrane Diffuser with Base
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.
- 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.
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.
What is the difference between an airstone diffuser and a rubber membrane diffuser?
The airstone diffuser and the rubber membrane diffuser both serve the same purpose; they provide aeration for your lake or pond. However, how they do it and what size they work best in is very different. The airstone diffuser can be quite convenient because it can easily be installed. The airstone diffusers can are more affordable, but they provide less oxygen. The rubber membrane is more expensive but offers more oxygen with smaller bubbles. The airstone diffuser can be ideal for smaller ponds.
The rubber membrane is an ideal solution for bigger ponds. This is because more bubbles are created and transported throughout the water, which makes more oxygen for your aquatic environment. Additionally it can also be argued that the airstone diffuser creates about the same amount of oxygen. The airstone diffuser gives off bigger bubbles and a sufficient oxygen level as the bubbles pop. To reiterate, both options are good, but your investment would depend on the price, maintenance frequency, and size of the pond.
