Replacement Disc and Tubular Membranes

This 9" circular membrane EPDM rubber air diffuser is used on many of our diffused aeration systems including the GENAIR and XTREMEAIR, AIRBOOST and ECONOAIR series of aeration systems. These circular membrane diffusers are excellent at aeration, circulation and destratifying your pond or lake environment. We also carry 6" tubular membrane replacement diffusers used on many of our earlier small pond models.
