OEM Element Cross-Reference

Find the Blue Membrane grade for your existing element — and what to check before you swap.

Element size Current duty

Before you swap, confirm the operating envelope:

Feed water TDS & temperature within the element rating
System operating pressure matches the grade
Target recovery ratio is achievable
Free chlorine dechlorinated to < 0.1 mg/L
Pretreatment (SDI / fouling) suits the element

Dimensional fit is necessary but not sufficient — a sound replacement also matches feed chemistry, pressure, recovery and pretreatment. Send your current element and feed data and we will confirm the cross-reference.
