Ideal for aerobic digesters, channels, equalization tanks and grit chambers. SSI Wide Band diffusers are available in 304L or 316L stainless steel. Designed to be clog-free with oxygen transfer rates of 0.5 to 0.8% per foot of submergence (1.7 to 2.5% SOTE/m). Reliable alpha value plus economic design to cover tank floor make the SSI Wide Band the ideal choice for mixing in aerobic digesters, channels, equalization tanks and grit chambers. Cast endcaps are welded all around. Removable deflectors supplied with each diffuser.

Highest possible quality and technology means years of trouble-free efficient operation. Highest possible SOTE independently tested per ASCE and lowest possible headloss. Compression molded EPDM membranes have very tight wall thickness tolerances, a long track record and exhibit even air distribution and minimal shrinkage over time. One-piece lightweight but strong ABS body makes handling during installation very easy. Single orifice on top center line of pipe means little chance for a single diffuser failure to contaminate all diffusers.

SSI Aeration, Inc.’s ECT70 tube diffusers provide low pressure loss, high oxygen transfer efficiency and ease of installation. We created this diffuser to offer you the highest quality product at the most affordable price.  The production method slashes the labor cost of manufacturing by 75% without sacrificing quality. How do we do that?  We use the same high quality membrane that we produce for our other products, but instead of snapping, gluing and clamping lots of plastic and rubber parts together, we instead take the membrane and mold the plastic housing all around it.    Then we mount the diffuser cartridge on a saddle, providing modularity around the affordable diffuser cartridge for easy replacement, instead of around the membrane.

SSI Aeration Patented Exclusive: The Snappy Saddle™ features a single seal that reduces risk of leakage by 50% and simplifies installation. Only requires one person to install. Available up to 7’-3” (2.2m) long in a single piece.
