FAIRCHILD MODEL 63
PNEUMATIC FILTER REGULATOR
Installation, Operation and Maintenance Instructions
Use the two 23/64 thru holes in the Body to mount the
Model 63. Mount the regulator with the Dripwell Drain
Plug at the lowest point for adequate drainage.
Clean all pipelines to remove dirt and scale before
installation.
Apply a minimum amount of pipe compound to the
male threads of the fitting only.
Do Not use teflon
tape as a sealant.
Start with the third thread back and
work away from the end of the fitting to avoid contami-
nating the regulator. Install the regulator in the air line.
The Inlet and Outlet ports are labeled “In” and “Out”.
Tighten all connections securely. Avoid undersized
fittings that limit the flow through the regulator. For
more information, see Figure 1.
NOTE:
The Model 63 has an Adjustment Screw that con-
trols output pressure. To increase pressure, turn
the Adjustment Screw clockwise. To decrease
pressure, turn the Adjustment Screw counterclock-
wise. For more information, see Figure 1.
Oil free air must be applied to the regu-
lator. If an air line lubricator is used, it
MUST be located downstream of the
regulator to avoid interference with per-
formance.
