Membrane Series Selector

Membrane choice decides chemical compatibility and whether the cartridge wets out, so it comes before pore size. Pick your duty, temperature and rating to get the ECOFILTRONE™ series worth sampling.

How the Selector Decides

Each duty maps to the series our catalogue lists for it, in the order shown. A series drops out when your temperature is above its limit or when it is not made in the rating you chose.

A rating of 0.2 µm is read as the catalogue class of 0.22 µm.
ECPAD is matched on its finer layer, 0.1 to 0.45 µm; the exact layer pair is confirmed on the datasheet.
The selector covers 0 °C upward and does not check O-ring or hardware compatibility, which we confirm with every quote.
