The Envirex Diamond™ series of membrane air diffusers from EVOQUA provides an advanced fine bubble science, and is ideally used to tend to the loopholes of a conventional membrane diffuser. It employs an EPDM-composed membrane. Also, the material can handle up to 50% more tension than any competitor. The raw material contains low soluble oils, which provides a long operating life for the membrane, at less costs. The "Diamond Aperture Configuration" produces high oxygen transfer, and a wider airflow of up to 5 SCFM.
