ULPA Filter Change
The ULPA filter change is performed with the vacuum turned OFF. Wear proper PPE, including
protective clothing, gloves, safety glasses, and respirator. Check with a supervisor to determine the
appropriate level of protection required based on the type of dust collected in the vacuum. If available,
we recommend changing the ULPA filter in a controlled environment, such as a sanding booth or
downdraft room.
1.
Loosen the knobs holding the prefilter screen
and carefully lift it out of the prefilter frame.
2.
Remove the prefilter by sliding it straight up.
3.
The prefilter holder is held in place by two metal
straps. Use a 5/32” Allen key to loosen the set
screws visible at the center of each strap.
4.
Once loose, the straps and the prefilter holder
can be removed by hand.
