FlexAir™ 9″ High Capacity Fine Bubble Diffuser



• Double your oxygen transfer with no piping changes
• Replace coarse bubble diffusers with fine bubbles for improved oxygen transfer
• Higher rate of airflow with fine bubble diffusers improves mixing

Our customers continually ask us for a replacement fine bubble diffuser that will provide improved oxygen transfer.  This is it!  The EDI FlexAir High Flow diffuser combines fine bubble oxygen transfer efficiency with mixing capability associated with high air volume.  It is a proven fact that fine bubble diffusers have superior oxygen transfer efficiency, which means that you have the option of reducing blower output to save energy for the long term. On the other hand, if you maintain the same cfm output currently utilized by your coarse bubble diffusers, you will get approximately 100% greater oxygen transfer with improved mixing. FlexAir high-capacity fine bubble diffusers offer the best of both worlds.

FlexAir high-capacity 9″ disc diffusers have a continuous operating range of 1 to 8 cfm and up to 10 cfm for intermittent service.

these air diffusers are engineered for maximum performance.
FlexAir® bubble disc diffusers are made of high-strength polypropylene with 3/4″ MNPT connections. Each diffuser has a minimum of 6,600 engineered air release orifices, which is up to 20% more than comparable models. The special design of the EPDM membrane with its engineered thickness taper, resulting in full utilization of the membrane surface even at low airflow operation! This results in improved oxygen transfer efficiency, along with maximum operational flexibility.

Every FlexAir® bubble disc diffuser has an integral “triple” check valve to prevent fluid backflow. Normal airflow range is 0–5 cfm. Resistance is about 10″ H2O when clean. Has fine bubble EPDM membranes installed and weighs 2 lbs.

Made in USA.
