FlexAir Disc Membrane – EDI®
The FlexAir™ disc diffuser is a fine pore flexible membrane or ceramic media diffuser that provides operational flexibility with maximum oxygen transfer efficiency. For ease of installation and maintenance, EDI's disc diffusers offer two connection methods: threaded and integrated saddle mount. The threaded disc diffuser can be installed in any 3/4-inch fitting or pipe nipple. Pipe with wall thickness equal to or greater than SCH40 can be drilled and tapped for connecting the diffuser. Additionally, diffusers can be installed using UDM (see "Specialty Disc Diffuser Items") when using thinner wall pipe for air distribution. The 9-inch diameter diffuser is also available with EDI’s innovative Integral Saddle Mount, which provides unmatched mechanical strength. Disc diffusers are constructed of glass-filled polypropylene and suitable for deep tank (high-temperature) applications. Alternate materials of constructions are available for special applications. FlexAir disc diffuser units are available with premium quality EPDM membranes. Multiple perforation patterns are available to optimize system performance. The flexible membrane diffusers incorporate a triple-check valve design to prevent intrusion of liquid or solids into the diffuser or air piping under normal on/off operating conditions.
