Product Details

• Non-clog design with integral check valve
• Interchangeable with 2” and 3” coarse bubble diffusers
• EDI’s PermaCap 5™ diffusers offer greater unit capacity than small diameter diaphragm coarse bubble diffusers and at less cost
• Engineered air outlet orifices and maximum orifice spacing serve to minimize bubble coalescence to achieve fluid interaction with maximum bubble formation and dispersion. The end result is improved oxygen transfer
• PermaCap 5™ diffusers can be mounted on the top or bottom of distribution piping to aid condensate removal from the air header
• The flexible membrane seats tightly against the center air inlet port serving as a check valve when the system is not in service to prevent infiltration of water and solids into the piping
• Membranes are available in either coarse or medium styles depending on the air flow desired
