Disc diffuser Roeflex®

for wastewater treatment

The disc diffuser Roeflex® stands out for its simple and robust design. The Roeflex® consists of a unique, convex shaped support disc. The disc is covered and enveloped by a flexible, slitted membrane of elastomer. In addition, a ring secures the membrane. Due to the disc’s unique convex shape the membrane is slightly lifted off the disc when air is supplied, thus allowing an even distribution of the fine bubbles generated. The membrane can be delivered in different materials (e.g. EPDM, Silicone) and slit patterns (e.g. HL, SL) according to the application. Function The disc diffuser Roeflex® is easily to install and can be mounted in two ways – with R 1/2” thread or with an adapter pin. The Roeflex® with R 1/2” thread is fixed to the distribution pipe by an inside thread, the Roeflex® with adapter pin is fixed with an EPDM-plug into a drill hole in the distribution pipe. Thanks to these fastening systems the Roeflex® offers least investment and installation costs.
