Felt Gasket Replacement Procedure
1.
If filter is in operation, start by bumping and draining the filter, and then shut down the
filter system. Isolate the filter, isolate the compressed air, deenergize the control panel
and drain the tank. NOTE: If tubes still seem to be caked with residue, we recommend a
Tubewash prior to shutting down the system. The tube elements will be removed from
the tube-sheet and if they are covered with debris, they will be more difficult to remove.
2.
Follow the procedure for “Lowering the Tubesheet into Maintenance Position”
3.
Follow the procedure for “Head Removal”
4.
Unbolt/Remove the hold down plate(s).
5.
Remove/pull out the tube elements by hand.
6.
Remove old tube-sheet felt gasket and replace with a new tube-sheet felt gasket.
7.
Inspect and reinstall tube elements.
NOTE
If damaged tubes are found, they should be replaced before final
assembly.
8.
Re-install hold down plate(s). Torque bolts to 30 ft-lbs.
9.
Re-install head and torque bolts following Figure 30: Head Torque, and all other
associated pipe, pneumatic tubing, and hardware.
