MAINTENANCE
WARNING !
Sharp Edges Can Cause
Personal Injury
Wear protective gloves to prevent cuts from sharp
edges.
CLEANING FILTER
Quality equipment, such as your Trion Port-A-
Cart cartridge air cleaner, will require minimum
maintenance to keep it in good operating condi-
tion. The motor is a totally enclosed, fan-cooled
type with permanently lubricated bearings. No
maintenance is required other than to routinely
check for foreign debris in the arm hood, the
drop-out tray and the motor blower compart-
ments. Rubber gaskets should be checked twice
a year. Aging occurs primarily due to ozone pre-
sent in ambient air and eventually hardens the
rubber and causes cracking and loss of seal.
Contact Trion for replacement parts at
800-884-0002.
MANUAL CLEANING
The Minihelic gauge, located on the top surface
of the unit, monitors static pressure across the
cartridge filter. Note the gage reading on initial
start-up. As contaminants collect, the static pres-
sure will increase until the pick-up or capture
zone becomes ineffective. Filter cleaning is re-
quired at this point. Again, note the static pres-
sure gage reading. The clean filter and dirty filter
readings may be used for future reference in de-
termining the cleaning cycle.
To clean the filter cartridge, turn the unit blower
off and close the damper in the pick-up arm. Re-
move the filter access cover. Using a com-
pressed air gun or nozzle, backflush contami-
nants from the cartridge filter by directing the air
through the filter from the center of the cartridge.
The particulate blown from the cartridge is col-
lected in the dust tray located below the filter.
When the filter cleaning is complete, the dust tray
may need to be emptied.
Return the unit to operation by reattaching the
filter access cover and opening the damper in the
pick-up arm.
OPTIONAL PULSE CLEANING
A backflush pulse cleaning system is avail-
able. It consists of an air tank, a pulse valve
and a manual switch. The air tank is located
inside the blower compartment. The pulse
valve is located to direct a blast of air into the
center of the cartridge from the blower end.
The actuator switch is located on the top sur-
face of the unit.
To clean the cartridge, turn the unit off and
close the damper in the pick-up arm. Connect
a dry/ clean compressed air source (80-120
PSI, 5.5-8.3 Pascals) to the air inlet on the
top surface of the unit. The built-in air tank will
fill from the connected air supply. When the
tank is full, the air flow stops. Initiate back-
flushing by pushing the pulse switch. Repeat
the pulse cycle several times for best results.
When the filter cleaning is complete, the dust
tray may need to be emptied.
Return the unit to operation by reattaching the
filter access cover and opening the damper in
the pick-up arm.
RECOMMENDED OPERATING RANGE
*
Resistance across the filter will increase
over time as contaminants become embedded
in the filter fibers. A reduction of 0.15” - 0.25”
after pulsing 5-10 times is common.
** When repeated pulsing and manual
cleaning does not reduce the gauge reading
below this range, airflow is typically insufficient
and the cartridge should be replaced.
