EPDM Membrane 9 Inch Bubble Disc Diffuser Strengthened PP Glass Fiber Support
EPDM membrane 9 inch fine bubble disc air diffuser
Fine Bubble Disc Diffuser is often used to disperse air bubbles in an extremely fine and uniform pattern for high oxygen transfer efficiency as its features of a unique split pattern and slit shapes.
At the same time, the check valve which is highly effective and integrated check valve can make sure the aeration zones to be easily shut down for air-on/air-off applications.
