Coarse Bubble Aeration


Greater unit capacity over other small diameter diaphragm coarse bubble diffusers at less cost

EDI FlexCap™ diffusers are ideal for aeration applications where intermittent coarse bubble operation is desired. FlexCap units are available with either 3/8-inch or ¾-inch NPT threaded (male) inlet to allow quick and simple installation into threaded pipe applications. Optional UDM (Universal Diffuser Mount) is available and provides a ¾-inch NPT (female) economical mounting solution for non-threaded applications.

FlexCap diffusers are particularly well suited for single drop pipe installations in package treatment plants and channel aeration. Also suitable for other aeration and mixing applications, including flow equalization, grit chambers, aerobic digesters, industrial, and mixing and scouring.
