Air Diffuser Membrane Tube Aerators EPDM/Silicone Fine Bubble Tube Diffuser
The rubber membrane pipe is made from imported ethylene-propylene-diene copolymer (EPDM) or silicon rubber, which makes the membrane anti-aging, corrosion-resisting and long service life, as long as 5 to 8 years.
The aerating hole is evenly formed, leading to good expandability and instant closing. During aerating work, the fine bubbles (1 – 3 mm) can be generated and the oxygenation utilization can be as high 35 – 42%.
