About the AirTAC GAFC500-20
The AirTAC GAFC500-20 is a GA-series two-unit air preparation set: a GAFR filter regulator joined to a GAL lubricator. It has 3/4" ports (PT thread as standard). Its regulating range is 0.15 – 0.9 MPa (20 – 130 psi); the low-pressure (L) version covers 0.15 – 0.4 MPa (20 – 58 psi). Components: GAFR500-20 filter regulator + GAL500-20 lubricator.
The units join with a quick, secure connector; regulation is stable and repeatable, and water and solid particles are removed efficiently. Differential + manual or automatic drains are available, and the bowls come in PC, metal or nylon. Proof pressure 1.5 MPa (215 psi), maximum operating pressure 1.0 MPa (145 psi), temperature -5 to +70 °C (no freezing). The clip-in round gauge reads MPa/psi on PT versions, bar/MPa on G versions and psi/bar on NPT versions.

Where the GAFC500-20 Is Used
Machine air inlet
Fit the GAFC500-20 where compressed air enters a machine or station.
Stable working pressure
Keeps valves, cylinders and tools at the pressure they need.
Automation lines
Clean, regulated air for pneumatic automation.
Choosing the Right GAFC500-20 Configuration
Start with the bowl and drain: PC is standard, C is metal and N is nylon; the standard drain is differential + manual, A gives an automatic drain.
Then the type: standard (S), 0.15 – 0.9 MPa (20 – 130 psi); or low-pressure (L), 0.15 – 0.4 MPa (20 – 58 psi). N means no pressure gauge.
Finally the configuration. The 40 µm element is standard; W gives a 5 µm element for cleaner air. K adds a check valve.
AirTAC GAFC500-20 FAQ
0.15 – 0.9 MPa (20 – 130 psi). Low-pressure (L) versions: 0.15 – 0.4 MPa (20 – 58 psi).
3/4" (20); PT thread as standard.
PC is the standard clear bowl; C (metal) suits areas with solvents or impact risk; N is nylon. The standard drain is differential + manual; A drains automatically.
