EPDM tube diffusers

EPDM membrane fine aeration bubble air tube 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.
