Airtac GAFC Air Service Unit GAFC20008ALN
The AirTAC Airtac GAFC Air Service Unit GAFC20008ALN is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1/4" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC20008ALN
This AirTAC GAFC20008ALN is a compact F.R.L. combination built for a 1/4in line, with the filter and pressure regulator sharing one body and a lubricator mounted on the same T-bracket. It handles a lower-pressure band of 0.15-0.4 MPa (20-58 psi), uses a 40 um element, and weighs just 590 g, making it a light addition to a small machine frame.
The automatic drain clears condensate from the 25 cc bowl without operator attention, while the 36 cc oil bowl feeds the lubricator with ISO VG 32 oil. No gauge is supplied, so the 1/8in gauge connection is where you would add one to read the set pressure. The two-piece layout means one less inter-unit joint to seal compared with a three-body train.

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 GAFC20008ALN Is Used
Precision Fixture Clamping
Feed a small pneumatic clamp on a benchtop assembly jig with regulated air at 0.15-0.4 MPa, keeping the force gentle on delicate parts while the automatic drain handles moisture from a humid shop line.
Lab Bench Air Supply
Supply a laboratory test rig that needs a low, stable pressure for a miniature cylinder or diaphragm pump, with the lubricator adding a fine oil mist to protect the moving parts.
Maintenance Workstation
Power a small air tool or blow gun at a maintenance bench where the lower pressure range prevents over-driving the tool, and the compact 590 g body mounts easily on a light frame.
Is the Airtac GAFC Air Service Unit GAFC20008ALN the Right Air-Prep Unit?
Choose the GAFC20008ALN when your application needs regulated air in the 0.15-0.4 MPa (20-58 psi) range and you want the convenience of an automatic drain. The PC bowl is the standard build, and the 40 um element handles general workshop air; step up to the 5 um W option if you feed precision valves. The missing gauge (N) keeps the package lean, but plan to add one at the 1/8in connection if operators need to verify pressure. Spares are the GAFR200-08 filter-regulator and GAL200-08 lubricator, both orderable separately. If the line must stay oil-free, omit the lubricator and choose a plain GAFR instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated band, so set your inlet pressure accordingly.
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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 590 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 GAFR200-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC20008ALN FAQ
The GAFC20008ALN operates on air with a pressure range of 0.15-0.4 MPa (20-58 psi), a max pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It works in temperatures from -5 to 70 C, uses a 40 um element, and requires ISO VG 32 lubricant. The drain bowl holds 25 cc, the oil bowl holds 36 cc, and the unit weighs 590 g.
The N in the code means no gauge is supplied, which reduces the unit's footprint and cost. If you need to read the outlet pressure, you can add a gauge to the 1/8in connection on the regulator body. The gauge scale for the default PT thread is MPa/psi.
