Product Description

Product Description

EPDM/Silicone Microporous membrane air diffuser disc used in
 supplying air for breaking down of contaminant in the biological treatment process, by the high oxygen transfer efficiency. It adopts ABS engineering plastics as the main body and is covered with a special rubber EPDM or silicone microporous membrane. The micro-holes will automatically expand while the air income and close while no air comes, which avoids the blocking of the holes. A non-return design is to prevent the mixture from entering and blocking the pipeline. The incoming air does not need special filtration and intermittent supply of air does not block the holes and pipes.

Features

EPDM/Silicone Microporous membrane air diffuser disc

Reverse folding structure
Non-return design preventing liquid from flowing back into the aeration system. EPDM Membrane, Anti-aging, corrosion resistance, acid and alkali resistance.
Very fine bubble, reducing the shearing to sludge particles.
Unique connector between diffuser disc and air pipeline,stronger connection, better sealing, avoiding the loosening of the connection due to the vibration.
More colors for choice.
