12 Inch Fine Bubble Disc Diffuser With EPDM Membrane For Water Treatment
Product Description
Efficient long-lasting Disc Diffuser designed to produce fine bubbles and maximize
oxygenation/aeration of water and its contents.
Membrane diffusers are far less susceptible to clogging or fouling than stone diffusers
because the algae cannot clog the membrane.
The membrane closes over the diffuser inlet which aids in preventing backflow of water into
the air supply line.
This is a low maintenance item, as well as low cost to maintain. The EPDM membranes are
replaceable, minimizing the impact on our environment.
