Features and Benefits

• The heavy-duty membrane, which will last 5-10 years, is specially formulated and molded and has 100 percent rebound memory.
• The precision perforated ‘I’ slits open when airflow is present, close when airflow is stopped, resist tearing, and stay cleaner longer.
• A standard ¾” diffuser pipe thread makes it convenient to replace other coarse bubble diffusers.
• Thickened center prevents ballooning and tapered membrane guarantees equal, fine bubble distribution across entire surface.
• Threaded lock ring tightens to hold the membrane firmly in place.
• Center vanes support the center of the membrane when airflow is absent.  
• Environmentally resistant and durable base is constructed of molded polypropylene.
