EDI ArmorCoated diffusers stand up to harsh environments. Their premium EPDM low-oil membranes make up the diffusers’ structural base, and their unique PTFE ArmorCoated finish offers increased capabilities in severe service applications. The coating helps prevent calcium carbonate fouling in hard-water applications, and waterside attack from unusual solids or aggressive wastewater materials.
Replacement membranes are available. Use them for routine maintenance, or to upgrade existing 9 or 12" diffusers from most manufacturers.
