Separ SWK2000/5U and SWK2000/5/50U Duplex

If you have a single engine and need to rely on your fuel supply - a SWK2000/5U duplex filter could be the ideal solution.


If your system is starved of fuel as the filter has removed too much contaminate, the easy option to maintain operation is to use the Separ SWK2000/5 duplex range. A simple chage-over handle controls the flow of fuel to either the left or right hand filters, whilst leaving the opposite unit free for maintenance.

The SWK2000/5U range is capable of handling flow rates up to 300 litres per hour (5 litres per minute), and has a 12mm input and output nut and olive connection. Separ UK offers a wide range of fittings to allow connection of your equipment to this filter, please ask for more details.
