About the Airtac GAFC Air Service Unit GAFC500N20SNW
This AirTAC GAFC500N20SNW is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure control, then a separate lubricator adds a metered oil mist downstream. The 3/4in port and 1910 g weight place it in the mid-large size class, suited for feeding a machine header or a multi-station line.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 5 um element for finer filtration. The nylon bowl is specified by the N code, and no gauge is supplied, so the 1/4in gauge connection is available if you add one later. The 108 cc condensate bowl and 225 cc oil bowl define the service interval.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFC Air Service Unit GAFC500N20SNW Is Used
Machine Tool Header
Feed a 3/4in header supplying coolant valves and clamping cylinders on a CNC lathe, where the 5 um element protects precision spool valves from fine wear particles.
Multi-Station Assembly Line
Supply a multi-station assembly conveyor with regulated air and lubricated actuators, using the 108 cc condensate bowl to handle moisture from a long distribution run.
Packaging Machine Air Prep
Prepare air for a carton erector's pneumatic cylinders and grippers, where the 225 cc oil bowl supports continuous cycling between scheduled maintenance windows.
Is the Airtac GAFC Air Service Unit GAFC500N20SNW the Right Air-Prep Unit?
Choose this GAFC500N20SNW when you need a 3/4in port with a 5 um element and no gauge. The nylon bowl is a material choice, not a performance upgrade, so confirm it suits your environment. The semi-auto drain dumps condensate on pressure drop, while the manual drain gives on-demand control. The PT thread carries an MPa/psi gauge scale if you fit a gauge to the 1/4in connection.
For a smaller line, the GAFC400 offers a 3/8in or 1/2in port with a 6000 L/min envelope at 0.7 MPa inlet, while this GAFC500 is plotted to 7000 L/min at the same inlet. The 5 um element traps finer particles than the standard 40 um, so expect more frequent element service. Spare parts are GAFR500-20 and GAL500-20, both orderable separately. Since the lubricator adds oil mist, choose a plain GAFR filter-regulator if the line must stay oil-free. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range.
Quick checklist
- ✓ Body size for your peak flow (3/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter-regulator first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 108 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1910 g unit on its bracket, not on the tubing.
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a plain GAFR500-20 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC500N20SNW FAQ
The GAFC500N20SNW operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 108 cc condensate bowl and a 225 cc oil bowl, with a total weight of 1910 g. The 3/4in port and 5 um element complete the specification.
The N after the port code means no gauge is supplied. The GAFC500 body has a 1/4in gauge connection, so you can fit a circular gauge there to read the set pressure. Without one, you cannot verify the regulated output, which matters when setting the 0.15-0.9 MPa range for a specific actuator.
