AVRO® membrane cross-reference
Find the AVRO® reverse osmosis element that corresponds to a DuPont, Hydranautics or Toray membrane, in 4″ and 8″. Equivalences are indicative and compiled to the best of our knowledge from publicly available manufacturer data sheets. Test conditions vary between brands — see the notes at the foot of this page.

About this comparison
The equivalences shown are indicative only and have been compiled to the best of our knowledge from manufacturers’ publicly available product data sheets. Performance figures are each manufacturer’s own published data, measured under that manufacturer’s stated test conditions, which vary between brands — feed concentration, pressure, pH and recovery are not uniform across the tables. Figures should therefore be read as a guide rather than as a like-for-like measurement.
This is not a complete listing. Some competitor membranes will not appear. Where a cell is blank, no equivalent was identified in the data sheets used to compile this table — it does not mean no comparable element exists. If the element you are replacing is not shown, contact us and we will identify the closest match.
Data sheets are revised from time to time and specifications may change without notice. This table is a selection guide and does not form part of any offer or warranty. Element performance depends on feed water quality, temperature, recovery and system configuration, none of which are reflected in a cross-reference. To size a system properly, run a projection using the AVRO® membrane projection tool available on this site, or contact us to discuss your duty.
AVRO is a registered trade mark of Avanale Enterprises Pty Ltd. Product names and model numbers of other manufacturers are the trade marks of their respective owners and are used here for identification and comparison purposes only.
