instrument air quality standards de-
scribe acceptable dirt, oil, and moisture
content. Due to the variability in nature
of the problems these influences can
have on pneumatic equipment, Fisher
Controls has no technical basis to rec-
ommend the level of filtration equipment
required to prevent performance degra-
dation of pneumatic equipment. A filter
or filter regulator capable of removing
particles 40 microns in diameter should
suffice for most applications. Use of
suitable filtration equipment and the es-
tablishment of a maintenance cycle to
monitor its operation is recommended.
The supply medium must be clean, dry air or noncor-
rosive gas that meets the requirements of ISA Stan-
dard S7.3-1975 (R1981). The supply pressure should
not exceed the following limits:
For the actuator and positioner, do not exceed
the maximum pressure rating of 100 psi (6.8 bar).
For the valve, do not exceed the maximum allow-
able thrust of the specific valve.
If a Type 67AF regulator is mounted on the actuator,
connect supply pressure to the supply connection on
the regulator. Connect the regulator output to the sup-
ply port S on the adapter housing. Gauge port S is
sealed with a plug. To install a supply gauge, unscrew
the plug and install an appropriate gauge.
