About the Airtac GAFC Air Service Unit GAFC300C08ALN
This GAFC300C08ALN is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. The 1/4in port and 1020 g mass place it in the mid-size class, suited for a single machine station or a small pneumatic circuit. The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 40 um element handles standard shop air.
The metal bowl is specified by the C code, and the automatic drain clears condensate without operator attention. No gauge is fitted, so the 1/8in gauge connection is left open for a later add-on. The 60 cc drain bowl and 98 cc oil bowl set the service interval, and the lubricator adds a metered ISO VG 32 oil mist after the pressure is set.

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 GAFC300C08ALN Is Used
Precision pressure setting
Set a delicate clamping pressure on a CNC fixture where the lower 0.4 MPa ceiling prevents over-forcing thin-walled parts.
Unattended condensate control
Feed a packaging machine's pneumatic sensors with the automatic drain clearing water from the 60 cc bowl during overnight runs.
Compact machine station
Supply a single-axis pick-and-place unit with filtered, regulated, lubricated air at 1/4in port size, keeping the footprint small.
Is the Airtac GAFC Air Service Unit GAFC300C08ALN the Right Air-Prep Unit?
Choose this GAFC300C08ALN when you need a lower regulated ceiling of 0.4 MPa (20-58 psi) and want the convenience of an automatic drain. The metal bowl is a build choice, not a performance upgrade, so confirm it suits your environment. The 40 um element is the standard grade; step to the W option for 5 um filtration if your downstream valves need finer protection. PT threads with an MPa/psi gauge scale are standard, and the gauge connection is 1/8in if you add one later. The reverse-flow valve is not fitted on this code; the K option adds it. Spares are orderable as the GAFR300-08 filter & regulator and the GAL300-08 lubricator. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300C08ALN FAQ
The working pressure range is 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, uses ISO VG 32 oil, has a 60 cc drain bowl and 98 cc oil bowl, and weighs 1020 g. The port is 1/4in with PT threads.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so you can add a circular gauge later if you need to read the set pressure directly. The lower 0.4 MPa ceiling is still adjustable without a gauge, but a gauge helps verify the exact setting.
