Do not exceed the maximum supply pressure of 1034 kilo-
pascals (150 pounds per square inch gage). Exceeding this
pressure could cause equipment damage.
The air supply pressure range is 172 to1034 kilopascals (25 to
150 pounds per square inch gage).
NOTE: The minimum supply pressure should be 34.4 kilopas-
cals (5 pounds per square inch gage) above the operating pres-
sure required by the actuator.
An external filter is recommended for Type AV positioners for pri-
mary filtration of the supply air. ABB provides supply air filters as
