ECD Diffusers

For cost conscious customers SSI Aeration offers our economy line of diffusers. The ECD diffusers (Patent Pending) are composed of a single piece  molded body integrated with SSI’s standard EPDM membrane. The single mold body allows SSI to offer a lower price point per diffuser while still including our proven EPDM membranes. The single mold design does not allow for membrane replacement, however given its low initial cost the entire diffuser is easily replaceable.

Available in both 7″ and 9″ diameter the ECD diffuser series features a 3/4 MNPT connection and is compatible with our PVC Grommet.
