Dura-Disc Plus diffusers feature injection molded membranes with self-cleaning, tear resistant "I" slits to provide a uniform bubble pattern ranging from 1 to 10 SCFM. This full-spectrum flow range allows maximum process flexibility in varying flow conditions. Membranes are permanently locked to the diffuser base to prvent blowout under maximum air flow. Under no-flow conditions membranes function as a check valve to prevent backflow.
Dura-Disc diffusers meausre 10" in diameter and have 3/4" Male NPT connections. Bodies are made of glass-reinforced propylene. Membranes are EPDM.
