SECTION 800
Filter Change Maintenance
Note: To be performed while there
is no welding occurring
1. Record
ΔP/Static pressure
reading from the controller
while the unit is operating.
2. Turn off the system.
(Blower motor only!).
3. Remove and replace Spark
Arrestance filters. (Metal mesh
filter in filter cabinet).
4. Remove and replace Spark Arrestance filters.
A.
Clean the entire inlet plenum to include:
i.
Spark arrestor filter (metallic filter) tracks and cover door
ii.
Inlet Plenum Box (after Metal Mesh filters)
Note:
Most particulate can usually be vacuumed out; however, if it is high in oil content, it
will tend to smear. If smearing occurs then a commercial degreaser can be used to assist in
cleaning. The cleaning does not have to return the system to new condition, but should be
void of pockets of particulate.
5. Turn off the main power disconnect.
6. Open the dust collector filter door.
7. Empty the dust tray and replace in its slot.
8. Remove the roughing filters, box filters, and bag filters Continue until all filters are removed.
Close the filter access door. (see Figure 3).
9. Climb on top of the dust collector and disconnect the 1st clamp on the ductwork up
from the flange attached to the unit. Slide the ductwork to the side so that the “Strike
Plate” is accessible from the top. Clean the plate by either vacuuming or scraping debris. If
scraping, just push the built up particulate over the edges and it will fall toward the dust
tray). Excessive build-up should be scraped only, as it is much faster to perform this task.
You may have to reposition the duct to get to all the plate. Clean the bottom of the top of
the collector as far as you can reach. Upon completion, reconnect the duct to its original
configuration.
