EPDM Bubble Diffuser Aeration Hose Air aerator fine tube bubble diffuser
Membrance fine bubble 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.
EPDM fine bubble membrane diffusers are constructed with premium quality EPDM membranes engineered for superior product
life,operational flexibility and maximum oxygen transfer efficiency. The units are ideally suited for continuous or on/off applications and require minimal maintenance for long-term performance

Good Aeration Effect
During aeration, the pressurized air enters the air channel, form an annular air chamber between the membrane and the ABS support tube, The membrane tube is inflated, and the air can be aerated to the water through micro holes in the membrane tube. When the air supply is stopped, the membrane tube is elastic contracted and tightly held on the support body, the micro holes are closed with the rebound contraction, prevent backflow of water into the air channel.
Advantages and Feature
The composite membrane has a long life and can reach 5-8 years, which completely solves the shortcoming of rubber membrane's easy tearing and short life.Strong collision resistance, not easy to damage.
Airholes are not easily blocked, sewage does not flow backwards.
All made of anti-corrosive material
