Air Diffusers and Bases

These air disc diffusers and weighted bases are very easy to install and the best way to complete your aeration system. Our rubber membrane disc diffusers are the best on the market. They are made of high quality EPDM rubber for use in the waste water treatment industry. They are very suitable for the aquaculture and water garden industries. These disc diffusers are the lowest back pressure diffuser made and only exert less than 6 inches of back pressure on the system. The high quality base is designed to be modular with 8 configurations available so you can add on to your system if needed.
