SW30 2521 – DOW Filmtec Seawater Membrane

Rainman Watermakers utilize the massively popular DOW Filmtec SW30 2521 membrane in their COMPACT membrane units.

With the correct care, you would expect 6-10 years of life from your membranes prior to replacement.

For the COMPACT Membrane, you will need two replacements.

Be sure to check out our services page to learn how to change your membrane on board, or simply send your unit to Seatask for membrane replacement.
