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.

EDI 316 SS Cast Diffuser Mount

The special 316SS diffuser mount tee is designed to mount 3/4-inch coarse bubble or fine bubble threaded tube diffusers on SS pipe. The mount is cast for maximum strength. A large diameter pipe contact area reduces pipe fatigue, making the diffuser mount suitable for even thin wall pipe. A special leveling bar on the bottom of the mount is utilized during the fabrication process to ensure diffusers will be level when installed. The 316SS material can be used with either 304SS or 316SS pipe.

Thru-Tube Mounting Connection Kit

The Thru Tube Mounting Connection Kit consists of a stainless steel nipple with air inlet holes and two special EPDM rubber gaskets. The gaskets provide a seal and also serve as a bushing to hold the assembly in the center of the air piping. The stainless steel nipple joins the two diffusers to complete the connection. The kit is designed to mount T-Series diffusers to square or rectangular air piping. Reference the diffusers in the T-Series section to select the proper diffuser for your application. Call for part number and pricing. Specify the air piping cross section dimension as well as the diameter of the outlet holes.
