About the Airtac GAFC Air Service Unit GAFC300C08ASNK
This AirTAC GAFC300C08ASNK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted downstream on a T-bracket. Air enters the 1/4in port, gets filtered to 40 um, and is regulated to 0.15-0.9 MPa (20-130 psi) before oil mist is added last. The metal bowl holds 60 cc of condensate, the oil bowl 98 cc, and the complete unit weighs 1020 g.
The automatic drain clears condensate without an operator, and the reverse-flow (reflux) valve is fitted. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/8in gauge connection. The catalogue flow curve is plotted to 3500 L/min at 0.7 MPa inlet, which serves as a sizing envelope rather than a rated capacity.

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 GAFC300C08ASNK Is Used
Precision valve feeding
Feed a small pneumatic valve manifold on a pick-and-place machine. The 40 um element and regulated 0.15-0.9 MPa output keep the valve pilots clean and consistent.
Machine tool lubrication
Lubricate a slideway cylinder on a lathe or milling machine. The 98 cc oil bowl provides a steady mist supply, and the automatic drain handles condensate from wet shop air.
Test bench air prep
Set up a clean air supply for a pneumatic test rig. The two-piece build takes less panel space than a three-unit train, and the metal bowl suits a workshop environment.
Is the Airtac GAFC Air Service Unit GAFC300C08ASNK the Right Air-Prep Unit?
Choose the GAFC300C08ASNK when you need a 1/4in port with a metal bowl and automatic drain. The metal bowl is a build choice, but the specification (1.0 MPa max, -5 to 70 C) is identical across materials, so confirm it suits your surroundings. The standard type regulates from 0.15-0.9 MPa (20-130 psi), and the 40 um element handles general workshop air; step to the 5 um element if you feed precision valves. The PT thread comes with an MPa/psi gauge scale, but this model has no gauge fitted, so plan to add one to the 1/8in connection. Spare parts are orderable as GAFR300-08 and GAL300-08. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so keep supply pressure near 1.0 MPa if you need the full output.
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 GAFC300C08ASNK FAQ
The working pressure range is 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). It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g. Use ISO VG 32 oil in the lubricator.
The N after the port code means no gauge is supplied with this unit. The GAFC300 body has a 1/8in gauge connection, so you can add a separate pressure gauge there to read the regulated output. Without one, you cannot visually confirm the set pressure.
