EPDM Membrane Fine Bubble Disc Diffuser

Short Description:

Fine bubble disc diffuser features a unique split pattern and slit shapes, which can disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency. A much highly effective and integrated check valve enables the aeration zones to be easily shut down for air-on/air-off applications. It can be operated over a wide range of airflows with minimum maintenance for long term performance.

Product Features (1)


Epdm can resist heat, light, oxygen, especially ozone. Epdm is essentially non-polarity, polarity solution and chemicalresistant, bibulous is low, it has good insulating properties.
Insoluble in water and any solvent, non-toxic and tasteless, chemical properties stable, except strong alkali, hydrofluoric acid not react with any material.
①High and low temperature resistant, working temperature can be 250ºC, good mechanical toughness; even if temperature drops to -196ºC also can keep 5% elongation.
②Corrosion - resistence to most chemical and solvents, showing inertia, strong acid resistance, water and various organic solvents.
③High lubrication - the lowest friction coefficient in solid materials.
④Non- adhesion - is the smallest surface tension in a solid material and does not adhere to any substance
