Pumps & Conveying System Components Chapter 3: Installation 30
Installing FCA, FCK, or FCS Filter Chambers
The filter chamber protects the vacuum pump from damage caused by material carry-over.
Primary system filtration occurs in the filter chamber, not in the vacuum receivers. This
reduces maintenance of vacuum receiver filters atop processing machines.
At the end of the conveying cycle to all on-line vacuum receivers, the dump delay cycle
occurs. Atmospheric air from the vacuum line is introduced to the filter chamber, equalizing
the pressure inside the filter chamber. The material discharge flapper valve falls open and
dumps the fines and dust collected during the conveying cycle.
The FCK Filter Chamber utilizes compressed air as a means of filter cleaning. The FCA
Filter Chamber does the same, except utilizes implosion cleaning. The FCS is able to clean
the filter by either method.
A compressed air filter cleaning blow back option is available for systems conveying very
dusty materials. Consult the Sales Department for more information.
Level and secure the filter chamber near the pump package. Use
3
/8” (9 mm) bolts to anchor
the filter chamber.
1. Connect the piping between the vacuum inlet valve on the pump package and the
tube stub on the filter chamber lid. For easy filter maintenance, install at least three
feet (3’ / 1 m) of vinyl flex hose at the end of the run to the filter chamber. The rest
may be hard piping as long as it is properly supported.
2. Run vacuum tubing from the tangential inlet tube to the vacuum header line servicing
the vacuum hoppers. Turn the inlet tube toward the header. Support the tubing
properly and make it vacuum-tight.
Note: Use of a system without a manufacturer-approved filter system installed
on the vacuum air inlet voids the blower warranty!
