The FlexAir® disc diffuser provides unmatched mechanical strength, operating flexibility and oxygen transfer efficiency. The innovative Integral Saddle Mount provides maximum mechanical integrity – up to 1.5 times the strength of conventional solvent welded mounting systems.The FlexAir® disc diffuser is provided with premium quality membrane materials that are engineered by the EDI Membrane Technologies division. EDI’s proprietary membrane materials are engineered for superior product life.Multiple membrane perforations are available to optimize the performance of the diffuser for maximum operating efficiency, air handling capacity, or operating pressure. An integral triple check valve feature prevents the backflow of liquid into the diffuser and piping.The FlexAir disc diffuser is ideally suited for on/off applications and requires minimal maintenance for long-term performance. The diffuser assembly and Integral Saddle Mount is available in glass-fiber reinforced polypropylene for maximum performance. This material option offers greater echanical and temperature capabilities as conventional PVC or CPVC products. The Integral Saddle Mount is compatible with any pipe material and is available in 3 inch, 4 inch, 90 mm and 100 mm diameter sizes. This flexibility allows the air conveyance system to be sized to match project objectives with minimum pressure loss.The Integral Saddle Mount features an air inlet port that inserts into the pipe and the KlicLocTM retainer positively locks the assembly to the lateral piping.Once installed, the assembly can withstand an external perimeter load in excess of 200 lb (90.7 kg) without failure. Precision die cut openings for high oxygen transfer, uniform air release, and low operating pressure .
EDI FlexAir® Magnum™ is a fine pore, flexible membrane diffuser that provides maximum operational flexibility and aeration capacity. The Magnum diffuser features a full circumferential perforation design. This design produces optimum aeration capacity performance. A full 380 in2 (0.245 m2) of perforated area is provided with a single Magnum diffuser. The geometry of the diffuser supports high diffuser density applications over 65% floor coverage when the highest aeration capacity is desired. Unique to the FlexAir product is the ability to configure the Magnum diffuser with a MicroPore or high capacity membrane for optimized aeration capacity and engineered operating pressure performance. All FlexAir diffusers are configured with premium quality membranes engineered by the Membrane Technologies division at EDI. Alternate membrane materials and perforation designs are available for non-standard industrial or municipal applications.An integral triple check valve feature prevents the backflow of liquid into the diffuser and piping. The FlexAir Magnum diffuser is ideally suited for on/off applications and requires minimal maintenance for long-term performance. The standard FlexAir Magnum membrane support tube is constructed of PVC for maximum chemical resistance and mechanical durability. ABS construction is recommended for high temperature applications or where cold temperature durability is required. The FlexAir Magnum diffuser is ideally suited for a wide variety of aeration and mixing applications including tank and lagoon facilities. For rigid piping applications, the FlexAir Magnum diffuser is available with the Spectrum Saddle Mount for maximum mechanical durability and ease of installation and maintenance. Unique to the Spectrum Saddle Mount is the ability to expand, relocate, reconfigure or add diffusers to match process demands.
