Now
that Nozzle Guard
has manufactured the most corrosion-resistant filter shell, do we stop
our quest to provide our customers with the best security against an
oil spill caused by a rusted-out filter? Of course not! To make sure
that our Triple
Corrosion Resistant shell reaches our customers
in an undamaged condition, we have designed Nozzle Guard with NO METAL COMPONENTS INSIDE THE
SHELL.
Competitors' filters contain a metal spring which presses against the
shell bottom. When the shell becomes weakened by corrosion, this spring
can actually push right through the rusted shell bottom, causing fuel
to leak out. Nozzle Guard
requires no spring or other metal parts inside its robust shell. This
means that there is no possibility that the
coating inside the shell has been damaged by scratching from a metal
spring or metal endcap (as used by competitors) during assembly of the
filter. This
exclusive Nozzle
Guard design assures users the very best
corrosion resistance available!
ALL FUEL OIL CONTAINS WATER.
The more water the fuel contains, the more likely that rust and
corrosion will occur. Excess water may be introduced into the
fuel during storage and handling--rain may enter an open cap or vent,
condensation may occur on the inside walls of a tank as it breathes in
moist air. Outdoor tanks are especially susceptible to condensation
problems.
WHEN WATER ENTERS THE TANK,
it settles to the bottom of the tank since it is more dense than water.
In side discharge tanks (or tanks with floating suction or other
elevated discharge point), water collects in the bottom of the tank
where it causes corrosion of the steel tank bottom and speeds formation
of sludge. During tank fills this settled material is stirred up so it
can enter the suction line and proceed to the filter where it
causes corrosion of the steel filter housing and plugging of
the filter element. In bottom discharge tanks, water and solids which
enter the tank settle to the bottom and are discharged directly to the
filter, where they will cause corrosion of the steel filter housing and
plugging of the filter element.
CANISTER-TYPE FILTERS
with replaceable elements (felt, gear-tooth, string-wound, etc.)
typically have steel canisters which are re-used after elements are
replaced. The canister may be damaged (bent) during dissassembly, and a
bent canister can result in an oil leak. These unprotected steel
canisters will rust through and leak in time and must be regularly
inspected and replaced when required. Failure to do so may cause oil to leak into the
customer's building. The shell of a Nozzle Guard Spin-on Filter
is changed every time the filter is replaced, eliminating the time and
mess required to inspect and/or replace a canister, and eliminating
the ultimate failure of a canister in the years to come.
SOME COMPETITORS
protect their filters from corrosion by plating the inside with a
"sacrificial" material such as zinc ("galvanized").
The thin coating of zinc is oxidized preferentially to the steel.
However once the thin layer of zinc is corroded, then the steel
underneath begins to rust. In severe conditions (e.g., when a filter
has significant amounts of free water in it) the zinc plating can be
exhaused, and the steel filter shell
can then rust through and leak. The shell of Nozzle
Guard has the zinc coating
protected by a barrier coating of UL approved
material., plus plastic on the bottom, to prevent
corrosion.
OTHER COMPETITORS
use a "barrier",
or paint coating to protect their steel shells. The paint forms a
barrier which keeps the corrosive agents (water and sludge) separated
from the steel. The problem with "barrier" protection is that
if the barrier is damaged by scratching or cracking, the steel
underneath has no protection and will rust. Or if oxidation is trapped
under the coating, the coating can blister and expose the unprotected
steel underneath. These competitive filters all contain metal
components which can potentially scratch the barrier coating during
filter assembly. Such scratches
through the coating will cause corrosion. In fact, rusting
at the point where the coating is damaged will occur at a faster rate
than if the steel was unprotected, since the attack is focused at this
point instead of over a wider surface. The shell of Nozzle Guard
has a barrier coating which is UL approved
(what spec does the coating on the filter you use meet?) and is protected
from scratching by the exclusive Nozzle Guard design which has no metal
parts inside the shell. If, in some unimaginable way, the
barrier coating in a Nozzle
Guard filter were damaged, the steel
underneath is galvanically protected
by the zinc coating underneath.
