RE: Aeration System Diffusers- EDI Sole Source
To Whom It May Concern,
Environmental Dynamics International (EDI) is the original equipment manufacturer of the FlexAir® MiniPanel Diffuser and Diffuser Membranes. This product was engineered, designed and manufactured at our headquarters located in Columbia MO. EDI is the sole manufacturer of the FlexAir® Aeration/Mixing System product line.
Specific to the proposed maintenance activities in the aeration basin, neither the original nor replacement membranes are commodity products. Membrane manufacturing employs proprietary membrane compounds, membrane extrusion processes, perforation processes, and quality control programs.
Please do not hesitate to contact EDI with questions or if you require any further clarification.
Sincerely,
Scott V. Hentges
Aftermarket Account Manager
