Description
1
Ground Rod
The grounding rod is driven into the ground and connected to the frame using a cop-
per cable. The grounding rod allows for the dissipation of static electricity that
would otherwise build up in the unit as fuel flows through the vessel.
2
Head Assembly
The head assembly is a removable cover secured to the top of the vessel by a stain-
less steel retaining band. The head assembly is removed to allow access to the coa-
lescer elements inside the vessel.
3
Retaining Band
The retaining band is a stainless steel belt that is used to secure the head assembly to
the top of the vessel A bolt mechanism is used to tighten the retaining band in place.
4
Outlet Coupling
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.
5
Differential Pressure
The differential pressure gauge displays the pressure difference across the filter/sep-
Gauge
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.
6
Inlet Coupling
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
hoses.
7
Water Drain Valve
A lever-operated ball valve used by the Operator to evacuate water from the sump.
8
Canister
The canister separates the coalesced water from the fuel.
9
Coalescer
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.
10
O-ring
The o-ring provides a seal between the head assembly and the vessel.
11
Bayonet Mount
The bayonet provides a mounting surface for the canisters containing the coalescer
elements.
12
Detector Kit
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.
13
Sight Gauge
The sight gauge indicates to the operator the level of water collected in the sump.
14
Fuel Drain Valve
A lever-operated ball valve used by the Operator to evacuate fuel from the vessel.
15
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.
16
Purge Valve
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
fuel loss.
