The filter is removing the particles from the seawater during intake. It is therefore only in use during ballasting. The filter screen is 40μm. The filter has a self-cleaning function by reversing the flow direction and flushing the untreated water back into the sea.
Optimarin offers three different 40 micron filters:
- FilterSafe basket type
- Boll & Kirch candle type

- All three filter types have automatic back flushing and are self-cleaning.
Key features include :
