The SSI ECD5oo Disc Diffuser System combines engineering excellence, superior componentquality, and a technically advanced product design. Proven highly durable and efficient inthousands of municipal and industrial installations around the world, this advanced system hasreliability built into every stage of performance.

SSI analyzed the Duck Bill (125mm Dia.) market some years ago and found that themain complaint of Duck Bill type diffuser was the air distribution between diffuserswas uneven, especially on longer pipes at low flux rate. Because of the flat surfacesolid settling and fouling of the membranes also was a potential issue.In response to those concerns, SSI introduced the ReliaBall (88mm Dia.) coarse bubblediffuser, which is also an Elastomeric Round Coarse Bubble Diffuser but has a differentbody shape. It has the check valve function with an orifice restriction, which ensuresthat air distributes very evenly between diffusers. EPDM rubber round membranes onthe ReliaBall are out of the highest quality raw material with low plasticizer to ensurea robust product.

The SSI 9" Disc Diffuser System combines engineering excellence, superior component quality, and atechnically advanced product design. Proven highly durable and efficient in thousands of municipaland industrial installations around the world, this advanced system has reliability built into every stageof performance. SSI's AFD27o comes in several membrane materials including our patented PTFEmembrane, designed to use less energy and require minimal maintenance. Industry standand size andshape are interchangable with other manufacturers. The diffuser base is molded with virgin polypropelinefor extended performance, and is highly efficient with airflow performance of 1.5-3.o SCFM.
