The choice between an ABS plastic basket and stainless steel is quite simple.

The ABS basket has excellent impact resistance and temperature tolerance, so can be used in any climate. It will outlast a 316 stainless basket, particularly in warmer waters where corrosion is more aggressive.
The choice to use a stainless steel basket is for those who require a different screen size than offered by the ABS. We can supply a standard 2mm perforated hole pattern and for custom orders we can also supply finer screening. (Minimum quantities will apply)
Note: If you have requirements to filter liquids other than seawater, our strainers are perfect for this as they are cast in 2205 grade stainless steel. We can discuss alternative filter material and membranes.
