The grounding rod is driven into the ground and connected to the frame using a cop-
would otherwise build up in the unit as fuel flows through the vessel.
The head assembly is a removable cover secured to the top of the vessel by lid bolts.
The head assembly is removed to allow access to the coalescer elements inside the
The differential pressure gauge displays the pressure difference across the filter/sep-
arator elements. When filter elements become contaminated, the flow through the
elements is impeded, causing an increase in pressure. The Operator monitors the dif-
ferential pressure gauge and changes the elements when the pressure difference
exceeds a threshold value.
Filtered fuel exits the vessel through the outlet coupling at the top of the vessel. The
outlet coupling is a standard camlock-type connection for fuel hoses.
Fuel Drain Valve
A lever-operated ball valves that can be opened by the Operator to evacuate fuel
from the vessel.
The canister separates the coalesced water from the fuel.
The coalescer is the primary filtering component of the filter separator. The coa-
lescer coalesces suspended water and removes particulate matter from the fuel
before it exits the Filter/Separator through the outlet.
The o-ring provides a seal between the head assembly and the vessel.
The bayonet provides a mounting surface for the canisters containing the coalescer
The detector kit consists of a short pipe nipple with camlock fittings on either end
that allow it to be installed in the outlet flow of the filter/separator unit. The nipple is
equipped with a probe that allows for sampling of the fuel exiting the filter/separator
for testing purposes.
The sight gauge indicates to the operator the level of water collected in the sump.
Water Drain Valve
A lever-operated ball valves that can be opened by the Operator to evacuate water
from the sump.
Fuel to be filtered enters the vessel through the inlet coupling located at the bottom
of the vessel. The inlet coupling is a standard camlock-type connection for fuel
Frame and Vessel
The vessel and frame are a single, welded assembly. The vessel contains the coa-
lescer elements of the filter/separator assembly. The frame protects the vessel and
attached components from damage and provides a stable, level mounting platform
for the vessel.
The purge valve is located on top of the vessel's cover assembly. The operator acti-
vates the purge valve to allow air trapped inside the vessel to escape with minimal
