Marine filtration problems come down to two fluids: water with oil in it, and fuel with dirt in it. Bag filtration handles both — in engine rooms, at fuel docks, and in shipyard wash-down systems — with hardware simple enough to service at sea.
What We Recommend
| Application | Media | Typical starting point |
|---|---|---|
| Bilge water — polishing oily water | Oil Magnet® oil-absorbing bags | Binds free & mechanically emulsified oil while filtering solids |
| Fuel transfer / fuel polishing | Felt, polyester | 10–25 µm |
| Ballast & seawater service | Polyester felt or mesh | 25–100 µm |
| Shipyard wash-down / stormwater | Felt; oil-absorbing where sheen is the issue | 25–50 µm |
| Hydraulic & lube oil clean-up | Felt, tight rating | 5–10 µm |
Practical Notes
- Oily-water sheen is the classic marine compliance problem, dockside or offshore. A standard particulate bag passes oil straight through; an oil-absorbing bag holds it in the bag for disposal.
- Salt service: specify stainless rings — standard carbon steel rings don’t last in seawater duty. Plastic rings are another option.
- Simple beats clever at sea. Bag change-out needs no tools and no calibration — one reason bag housings persist in engine rooms. Keep spares aboard in the right size.
