How It Works and Technical Data
- Fitted in the bilge pump discharge line, the filter element (a mass of surface-treated fibres) absorbs and retains up to 95% of oils, fats and emulsions, and isolates heavy metals; it can be washed and reused after the oil is collected.
- Heavily contaminated water holds 100 to 200 mg/l (100 to 200 ppm); the element handles up to 600 mg/l and absorbs approximately 600 g of oil – at an average 40mg/l that is about 15.000 liters of water.
- Use a bilge pump of approximately 20l/min; two separators in parallel increase capacity. The separator adds resistance in the discharge line.

Mounting
- Mount on a vertical bulkhead in an easily visible place, always above the waterline and high enough to stop bilge water running back or siphoning (installation examples show min. 30 cm (12")); allow for heel on a sailboat.
- Use flexible 19 mm hose on both sides (pump to separator, separator to through-hull); fit with water or soap only, never oily products; stainless steel hose clamps.
- With very long hose runs, fit a check valve just downstream of the bilge pump to stop it cycling on and off.
Changing the Filter
- Check the element regularly and replace it before it is saturated with oil.
- Unscrew the cap by turning the housing anticlockwise – by hand only, never with tools.
- Take out the 15 loose discs one by one, clean the housing and insert the new discs one by one.
- Grease the O-ring (silicone oil or PTFE spray), refit the cap by hand and check the seal: a badly closed cover lets bilge water escape past the O-ring.
- Before frost, drain the separator by removing the hose couplings (there is no drain valve).
