Airtac GAFC Air Service Unit GAFC20008ALNK
The AirTAC Airtac GAFC Air Service Unit GAFC20008ALNK 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 GAFC20008ALNK
This GAFC20008ALNK is a compact F.R.L. combination built as two units on one T-bracket: a filter-regulator body handles filtration and pressure setting, then a lubricator adds a metered oil mist downstream. With its 1/4in port and 590 g mass, it suits small jigs, single actuators, or short pneumatic lines where space is tight.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), which is about 44% of the standard 0.9 MPa ceiling. The 25 cc condensate bowl and 36 cc oil bowl define service intervals, while the automatic drain clears water without operator attention. A 40 um element is fitted, and the reverse-flow valve is included as an ordering option.

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 GAFC20008ALNK Is Used
Precision jig clamping
Feed a small bench-mounted jig or fixture with regulated air at 0.15-0.4 MPa, where the lower pressure range protects delicate workpieces from over-force.
Single actuator stations
Power one air cylinder or a compact slide on a manual assembly bench, with the automatic drain keeping the 25 cc bowl clear during intermittent use.
Lab air preparation
Supply a small pneumatic test rig or lab fixture with filtered, lubricated air at a controlled low pressure, where a 1/4in port and compact footprint fit the bench.
Is the Airtac GAFC Air Service Unit GAFC20008ALNK the Right Air-Prep Unit?
Choose this GAFC20008ALNK when your circuit needs a 1/4in port and a regulated band capped at 0.4 MPa (20-58 psi). The automatic drain suits wet or unattended lines, and the PC bowl is the standard build - confirm it matches your environment since the catalogue gives no material-specific ratings. The no-gauge version leaves a 1/8in connection if you add one later; the PT thread carries an MPa/psi scale on any fitted gauge. The reverse-flow valve is present per the K code, and the 5 um element option (W) is available if finer filtration matters more than service life. Spare parts are orderable as GAFR200-08 and GAL200-08. Max supply of 1.0 MPa leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan 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 GAFC20008ALNK FAQ
The GAFC20008ALNK operates from 0.15 to 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). Temperature range is -5 to 70 C. It has a 25 cc drain bowl and 36 cc oil bowl, weighs 590 g, and uses ISO VG 32 lubricant. The element is 40 um, the drain is automatic, and no gauge is supplied.
The N after the port code means no gauge is fitted, leaving a 1/8in connection if you want to add one later. The K code indicates a reverse-flow (reflux) valve is included, which the catalogue shows as a separate pneumatic symbol. This model also uses a lower-pressure regulator capped at 0.4 MPa, so it is not suitable if your circuit may need more than that.
