Dual Disc Rubber Membrane Diffuser with Base and Risers
This Dual Disc Rubber Membrane Diffuser with Base and Risers really circulates your pond or lake!
We’ve searched far and wide to develop 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.
- The base can quickly be filled with sand or gravel to sink
- ½” fittings
- Includes Riser Tuber
- Backflow valve to prevent water from entering the airline.
This Dual Disc 9″ membrane is used in the water treatment industry to really move the water through the precision perforated slits. It is rated for up to 8.5 CFM and perfect for lakes or ponds, especially where you’re only running one diffuser. The unit comes with a backflow valve and 1/2″ fittings to plug into your 1/2″ airline.
This diffuser also comes with a base that can be filled with sand or gravel, so it sinks to the bottom of your pond and Riser Tubes to further elevate your diffusers for maximum lift and circulation.
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. 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.
