Instead of airstones these diffusers use a flexible membrane EPDM membrane to resist clogging and fouling. These are the recommended diffuser in ponds or lakes that have a high level of organics or nutrients. No need to add sand or rocks in to a hollow base like so many diffusers! These diffusers assemblies need no extra weights!
These diffusers do not have the same efficiency as the airstone diffuser assemblies but they are ideal for the pond owner or manager who wants to install an aeration system that requires the least amount of maintenance possible. These diffuser assemblies require less PSI and so are perfect for linear air pumps in most ponds! Can also be used with rotary vane compressors, high pressure blowers, rotary claw air compressors or piston compressors for a simple and easy aeration or mixingsystem.
The EPDM membrane diffuser tubes require less maintenance compared to airstones and resist fouling better than airstones. Ideal for lakes and ponds or wastewater applications where a high organic load makes using traditional airstones problematic.
Available Format
![]() 4 x 6" EPDM membrane diffuser tubes. *Some assembly is required. Airflow 1.5 - 2.4 CFM. Use in ponds and lakes under 12 feet deep. Equipped with 5/8" barbed connector to fit your 1/2" or 5/8" airline. These weighted diffusers lay flat upon the lake or pond bottom so disturbed sediments is minimized and airstones do not become fouled or covered in muck due to the underlay which keeps the diffusers out of the sediment. . |
![]() 6 x 10" EPDM membrane diffuser tubes. *Some assembly is required. Airflow 3.0 - 7.0 CFM. Use in deeper ponds and lakes over 12 feet deep. Extreme pumping rates! Features six 10" EPDM diffusers on a weighted base. The most extreme aeration and circulation available.Equipped with 5/8" barbed connector to fit your 1/2" or 5/8" airline.

The flat base has holes for attaching mooring ropes if you wish to add a float to the diffuser for future retrieval or removal or re-placing of the diffuser. You can also tie a float a few inches below the surface so you don't have to see the float.
*Some assembly is required. The assemblies ship in multiple boxes to protect the specialized diffusers.
