The Los Membraan NC60 is an OEM-quality replacement diaphragm designed for ELBI hydro-pneumatic and expansion vessels. Built for reliable separation of air and water in domestic and light-commercial systems, this replacement membrane restores pump efficiency, prevents waterlogging and extends the service life of your tank. Ideal for use in AF/AC series and comparable ELBI tanks, the NC60 membrane meets the demands of potable water and heating applications while offering durable, food-grade elastomer construction for long-term performance.

Key features

• Compatibility: fits ELBI AF/AC style expansion vessels and many hydro-pneumatic tanks (OEM replacement part).
• Material: durable EPDM/food-grade elastomer membrane for potable water and heating system compatibility.
• Function: restores drawdown, prevents waterlogging, improves pump cycling and system efficiency.
• Easy installation: replaceable bladder design for faster maintenance and lower downtime.
• Corrosion protection: designed to work with tanks featuring epoxy powder coat or protective liners.

Technical and fit guidance: confirm tank model and capacity before ordering to ensure correct bladder size and connection type. ELBI offers replaceable bladders and guidance for selection and service, and many authorized distributors list replacement EPDM membranes for AF-series vessels. For installation, depressurize the tank, drain water, and follow manufacturer instructions or consult a licensed technician if unsure.
