Product Description
FlexAir Threaded Disc Diffuser, 9" Disc Standard Fine Fine
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, results in full utilization of the membrane surface, even at low airflow operations. 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.
