The diffuser base plate is required for any membrane disc diffuser grid with a Sanitaire 2300 style holder. The base plate is installed inside the holder and provides not only support, but enables proper seating of the membrane's integrated check valve and O-ring.
When modifying your aeration grid from ceramic to membrane diffusers, a base plate is required.
