Fuel Filter

Five separate stages of filtration ensure 99.9% water separation
at max flow rate. The Series 2000 is designed to reduce wear on
fuel pumps and ensure full RPMs for the most modern diesel
engines. The unique back flushing capability significantly extends
filter change intervals reducing down time and filter element cost.
Separ 2000 series offers:
Most Economical and Reliable Filter/Separator System
Smallest Space Requirement for Filter Changes
Low Flow Restriction (pls. see table below)
Easy Installation (In and Out ports on each side)
Simple Maintenance (back flushable filter element

Filter replacement elements are available in 10 micron and 30 micron water blocking material. A 60 micron
cleanable stainless steel cartridge can be used for heavily contaminated fuel (not recommended as primary filter).
To monitor and get the optimal lifespan out of your filter element we recommend installing the matching
LG-X Fuel Conditioner and the optional liquid filled stainless steel compound gauge (Model # 30652).
All Separ models listed above are also available as switchable duplex filter
setups that enable you to service one filter without shutting the engine down
(Gauges shown are optional).
