About the Airtac GAFC Air Service Unit GAFC500C20LN
This AirTAC GAFC500C20LN is a two-piece F.R.L. combination built for a 3/4" line. The first body houses the filter and regulator together, so air is cleaned and set to pressure in one step; the lubricator then adds a metered oil mist downstream. With a lower-pressure regulator, the working range is 0.15-0.4 MPa (20-58 psi), and the metal bowls hold 108 cc for condensate and 225 cc for oil.
The 1910 g assembly uses quick clamps on a T-shape bracket, and the metal bowl is specified by the C code. No gauge is supplied with this model, so the 1/4" gauge connection is available if you need to read the set pressure. The 40 um element handles standard shop air, and the unit is rated for -5 to 70 C with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure.

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 GAFC500C20LN Is Used
Machine tool lubrication
Feed a 3/4" line on a CNC lathe or milling machine, where the lower 0.4 MPa ceiling suits light clamping circuits and the lubricator keeps way slides and spindle bearings oiled.
Assembly station air prep
Prepare air for a multi-station assembly bench with pneumatic screwdrivers and pick-and-place units, using the 108 cc drain bowl to handle condensate from a wet compressor line.
Packaging line regulator
Set a stable 0.3 MPa supply for a carton erector or case packer, where the lower pressure range prevents over-force on delicate film seals and the oil mist protects cycling cylinders.
Is the Airtac GAFC Air Service Unit GAFC500C20LN the Right Air-Prep Unit?
Choose the GAFC500 when a 3/4" port and 1910 g mass suit a fixed machine installation rather than portable tooling. The L type tops out at 0.4 MPa, so confirm your actuators never need more than that; if they do, step to the standard 0.15-0.9 MPa S type. The metal bowl is a build choice, and the catalogue gives no impact or chemical data, so verify it suits your surroundings. The semi-auto drain dumps condensate when pressure drops, with a manual drain for on-demand use, and the 40 um element is the standard grade. The PT thread carries a gauge scale in MPa/psi, though no gauge is fitted here. For spares, order the GAFR500-20 filter-regulator and GAL500-20 lubricator separately. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this unit's 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 GAFC500C20LN FAQ
This lower-pressure F.R.L. combination operates at 0.15-0.4 MPa (20-58 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C, and the 108 cc drain bowl and 225 cc oil bowl are both metal. Use ISO VG 32 oil in the lubricator, and the complete unit weighs 1910 g.
The N after the port code means no gauge is supplied. The GAFC500 has a 1/4" gauge connection, so you can add a circular gauge later if operators need to read the set pressure. Until then, the lower-pressure regulator is adjusted without a visual reference, so use a test gauge or a calibrated adjuster during setup.
