The FlexAir® Pro threaded 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.
