Pressure Regulator for Air Arms FAC

Pressure regulator for Air Arms FAC PCP air rifle. This model will give you a more consistent performance and improved accuracy. The installation is really simple and you don’t have to drill any holes into the air cylinder. 

You need to drain the air cylinder of any air first and then unscrew the coupling between the air cylinder and the barrel. Unscrew the air cylinder next and loosen the pressure gauge so you can reach the the bolt under it.

Then you can unscrew the brass chamber and replace it with the regulator. Apply silicone spray to it and screw it in with a slow circular motion. You can tighten the bolt located under the pressure gauge once the regulator is set in place. All you need to do then is to screw the air cylinder and coupling back.

The pressure output can be adjusted with the flat head screwdriver from 100 to 150 bar. The total scale range corresponds to approximately 1/2 turn. Unscrewing, or screwing the setting screw for more than one turn may result in failure of the regulation. To increase the pressure you need to turn the setting screw counterclockwise. To decrease the pressure you must turn it clockwise.
