How to Install a New ULPA Filter with the Bag-
In/Bag-Out Procedure
The XPert line of enclosures include a true bag-in/bag-out filter disposal system
for safely removing the ULPA filter and protect the worker from toxic powders
and particulates. See Figures 6-1 for the Bag-In/Bag-Out Procedure. For your
safety, wear appropriate personal protective equipment during the change of filters.
If working with biohazardous materials, use the decontamination procedure
outlined in this chapter. (Consult your Safety Officer before performing filter
changes).
Do NOT contact blower wheel while still in motion.
NE PAS être en contact avec la roué du ventilateur tant qu’il est
en marche.
1. With the enclosure OFF, remove the front panel secured by two screws on
top of the enclosure.
2. Remove the bungee cords and retaining strap on the bag and extend it out.
The retaining strap provides an extra level of safety even though the
enclosure is under negative pressure when the blower is on.
3. Loosen the two filter clamp bolts with a 9/16" socket securing the ULPA
filter. See Figure 4-1.
4. Place both arms in the rear gloves of the bag, and carefully draw the ULPA
filter out of the enclosure. Rest the filter on the floor, table or cart.
Remove arms from bag gloves.
5. Create two seals between the enclosure bag access port and the old filter.
Seals can be heat sealed or sealed with tie wraps. Cut off the bag between
the two seals and leave the bag stub on the access port to the enclosure.
6. Place the new ULPA filter in the new bag. Then place the new bag and
new filter over the old bag stub and onto the enclosure access port.
7. Carefully remove the old bag stub using the single glove near the access
port. Reattach the retaining strap on the perimeter of the new bag at the
enclosure access port. Draw the old bag stub into the single glove and turn
the glove inside out. Double seal this glove and cut off the glove with the
contaminated bag stub inside.
8. Carefully install the new ULPA filter and uniformly tighten the two filter
clamp bolts until the filter gasket is compressed 50%.
9. Carefully fold and roll the new bag in four-inch pleats and push the bag
into the access port. Reinstall the retaining strap and bungee cords. Turn
the enclosure ON to draw a vacuum on the bag. Reinstall the front panel.
