Description
The AFR3 Filter Regulator allows air pressure to be adjusted to match the requirements of the actua-
tor (see the documentation envelope or IOM package supplied with your hardware for proper pressure
settings). An internal filter traps water and other contaminants before they can cause excessive wear
or damage to actuator components.
Installation
Blow out the air supply pipe to remove scale or other contaminants prior to installation. Install the
regulator as close as possible to the instrument being supplied. For best filter drainage, position the
unit so that the drain valve is at the lowest point on the dripwell housing. The unit must be installed
with the flow in the direction of the flow arrow on the body cover and the bowl down.
Operation
To increase regulated pressure, pull adjusting knob up and turn clockwise. To reduce pressure, turn
knob counterclockwise. To lock knob, push down.

WARNING!
The AFR3 is designed for air service only. Maximum allowable inlet pressure is
250 psi (1725 kPa). Operating temperatures are 32 to 150 ºF (-0 to 65 ºC).
To avoid exceeding outlet pressure limits while in service, a pressure relieving or
pressure limiting device should be provided.
