How Does it Work?

XOil filter technology

Oily water is pumped down outside the XOil filter cartridge and the oil is bonded within the filter media. The water travelling up through the centre of the filter, and out of the boat, is almost entirely free from oil.

Really oily bilge water, around 250 milligrams per litre, is generally reduced to below 12 milligrams per litre. Normal bilge water will be reduced to below 5 milligrams per litre.

Serious oil spillages should be dealt with using absorbent pads prior to pumping through the filter. Filter cartridge replacement is explained in the useage instructions.

A privately owned and well maintained boat should not need to replace the filter cartridge more than once a year.One drop of diesel in half a litre of water equates to roughly 40 milligrams per litre. This is well over the legal limit set by MARPOL.
