About the AirTAC GAFR500-20
The AirTAC GAFR500-20 is a GA-series filter regulator: one unit that filters and sets the pressure. It has 3/4" ports (PT thread as standard). It regulates from 0.15 to 0.9 MPa (20-130 psi). The low-pressure (L) version regulates from 0.15 to 0.4 MPa (20-58 psi).
The round gauge clips in, saving space, with a magnified, easy-to-read dial; the knob locks by pressing it in and a balanced valve keeps the set pressure stable. A swirl guide separates water and particles before a 40 µm or 5 µm element, and the bowl comes in PC, metal or nylon. Maximum operating pressure is 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), operating temperature -5 to +70 °C (no freezing).

Where the GAFR500-20 Is Used
Machine air inlet
Fit the GAFR500-20 where compressed air enters a machine.
Stable working pressure
Set and hold the pressure your valves and cylinders need.
Pneumatic stations
Feeds cylinders, valves and tools on one air line.
Choosing the Right GAFR500-20 Configuration
Start with the bowl and drain: PC, metal or nylon bowls. The standard drain is differential-pressure plus manual; A gives an automatic drain.
Then the type and gauge: standard (S) regulates 0.15 to 0.9 MPa, low-pressure (L) 0.15 to 0.4 MPa. The round gauge clips in; its scale follows the thread: PT reads MPa/psi, G reads bar/MPa, NPT reads psi/bar. N means no gauge.
Finally the configuration. A mounting bracket is included unless the code carries J. The 40 µm element is standard; W gives a 5 µm element for cleaner air. K adds a check valve.
AirTAC GAFR500-20 FAQ
0.15 to 0.9 MPa (20-130 psi). Low-pressure (L) versions: 0.15 to 0.4 MPa (20-58 psi).
3/4" (20), PT thread as standard.
The clip-in round gauge reads MPa/psi on PT versions, bar/MPa on G versions and psi/bar on NPT (T) versions. N means no gauge.
