TECHNICAL DATA |
INSTALLATION |
|
|
|
|
Fluid: Compressed air |
1. Shut off air pressure. Install filter/regulator in air line - |

|
|
|
Metal bowl: 17 bar (250 psig) |
● upstream of lubricators and cycling valves, |
|
|
|
|
Operating temperature*: |
● as close as possible to the device being serviced. |
|
|
|
|
Transparent bowl: -20° to +50°C (0° to +125°F) |
2. Connect piping to proper ports using pipe thread sealant |
