Description

The AFR2 Filter Regulator allows air pressure to be adjusted to match the requirements of the actuator

(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 words "IN" and "OUT" are cast

into the body to indicate the direction of flow.

The AFR2 is designed for air service only. Maximum allowable inlet pressure is 250 psi

(1725 kPa). Operating temperatures are 0 to 160 ºF (-18 to 71 ºC).

An internal relief circuit provides limited downstream overpressure protection, but to

avoid exceeding outlet pressure limits while in service, a pressure relieving or pressure

limiting device should be provided.

Before turning on supply air, back off the square-head adjusting screw until there is no compression of

the range spring. After turning the supply pressure on, turn the adjusting screw clockwise to increase

outlet pressure.

To adjust the filter regulator, turn the adjusting screw as follows:

1. Clockwise to increase outlet pressure.

2. Counterclockwise to decrease outlet pressure.
