5-3 Maintaining VacTrac Filter Chambers
VFC Filter Chambers
VFC filter chamber maintenance is much easier if you use vinyl
flex hose for making the final connection to the cover.
To check the filter element:
1. Unlatch the clamp that secures the cover assembly.
2. Lift off the cover and look for element fouling or wear:
• If the filter is worn, replace with P/N A0536945
(VFC15) or P/N A0536947 (VFC35).
• If the filter is lightly soiled, remove the filter and
clean with compressed air. Blow it out from the
inside.
3. To remove the filter:
• Note the orientation of the components.
• Unscrew the retaining cover.
4. Wipe down the gasket and filter retainer/VFC cover mating
surfaces to ensure a good seal.
5. Blow out the cartridge filter with compressed air. Blow
from the inside out.
6. Re-install the filter and filter retainer. Do not over tighten
the retainer. A snug fit is required for a proper seal.
7. Secure the cover assembly with the clamp.
• Periodically inspect the flapper assembly gasket and
disk for signs of wear. A good vacuum seal is
important for proper operation.
• Periodically inspect the flapper dump assembly for
proper operation. The flapper should swing freely.
Note: The counterbalance should be adjusted so the flapper
remains open from 3 /
16
” (4 mm) to 1 /
4
” (6 mm) when not
under vacuum.
