EDI’s 7 or 9 inch diameter diffusers employ a ¾" NPT diameter male
threaded connection for ease of installation/maintenance and universal
application. Units can be mounted using the universal diffuser mount.
The 9 Inch diffuser is also available with EDI’s saddle mount. Disk
diffusers are constructed of glass-filled polypropylene and suitable for
deep tank applications. The membrane is constructed of high quality
EPDM. The flexible membrane diffuser incorporates an external triple
check valve design to prevent intrusion of liquids or solids in the
diffuser or air piping under normal on/off operating conditions.
