About the Airtac GAFC Air Service Unit GAFC300N08LNK
This AirTAC GAFC300N08LNK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted on the same bracket. It handles a 1/4in port and operates in the lower pressure band of 0.15-0.4 MPa (20-58 psi), with a 40 um element filtering the air before regulation.
The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, so the 1020 g unit needs a solid panel mount rather than tubing support. A reverse-flow valve is fitted, and the gauge connection is 1/8in since no gauge is supplied with this model.

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 GAFC300N08LNK Is Used
Precision pressure setting
Set a lathe's air chuck to 0.3 MPa (43 psi) with the lower pressure range, giving fine adjustment for delicate workholding without over-pressurizing the part.
Assembly line lubrication
Feed a small pneumatic screwdriver on an assembly bench with filtered, regulated air and a metered oil mist, keeping the tool running smoothly on repetitive fastening tasks.
Low-pressure test rig
Supply a leak-test fixture that needs a gentle 0.2 MPa (29 psi) test pressure, using the 1/4in port to connect to the rig's manifold and the 40 um element to protect the test valve.
Is the Airtac GAFC Air Service Unit GAFC300N08LNK the Right Air-Prep Unit?
Choose this GAFC300N08LNK when your circuit needs regulated air at 0.15-0.4 MPa (20-58 psi) and a 1/4in port. The nylon bowl is a build choice, but the common specification of 1.0 MPa max and -5 to 70 C applies regardless, so confirm the material suits your environment. The semi-auto drain dumps on pressure drop while the manual drain works on demand, and the 40 um element handles standard shop air. For oil-free lines, omit the lubricator and select a plain GAFR300-08 filter-regulator instead. Spares are orderable as GAFR300-08 and GAL300-08. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the 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 GAFC300N08LNK FAQ
The GAFC300N08LNK is a lower-pressure F.R.L. combination with a working range of 0.15-0.4 MPa (20-58 psi). Maximum pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 lubricant. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g.
The N after the port code means no gauge is supplied with this unit. The gauge connection on the GAFC300 body is 1/8in, so you can add a compatible gauge later if you need to read the set pressure directly. The reverse-flow valve is fitted as indicated by the K code.
