About the Airtac GAFC Air Service Unit GAFC20008LNK
This GAFC20008LNK is a two-piece F.R.L. combination: a GAFR filter-regulator in one body plus a GAL lubricator, mounted on a T-bracket with quick clamps. Air is filtered and pressure-set in the first body, then the lubricator adds a metered oil mist last, so oil never passes back through the regulator seat. The 1/4in port and 590 g mass suit a compact machine header or a single actuator station.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 1.0 MPa (145 psi) maximum supply. The 40 um element handles standard shop air, and the 25 cc condensate bowl plus 36 cc oil bowl define the service interval. No gauge is supplied; the 1/8in gauge connection allows adding one later. A reverse-flow (reflux) valve is fitted, shown as a separate symbol in the catalogue.

Constituent units, orderable separately as spares: GAFR200-08 filter & regulator, GAL200-08 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.

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 GAFC20008LNK Is Used
Precision Jig Clamping
Feed a single 1/4in actuator on a benchtop assembly jig, where the lower 0.4 MPa ceiling prevents over-clamping delicate parts and the 590 g weight mounts directly to a small frame.
Lab Air Bench
Supply a test fixture with regulated air at 0.15-0.4 MPa, using the 36 cc oil bowl to lubricate a small pneumatic cylinder while the 25 cc condensate bowl handles moisture from a wet compressor line.
Packaging Line Sensor
Protect a photoelectric sensor air-blow nozzle on a packaging line, where the 40 um element filters debris and the semi-auto drain clears condensate during shift changes without operator attention.
Is the Airtac GAFC Air Service Unit GAFC20008LNK the Right Air-Prep Unit?
Choose this GAFC20008LNK when your circuit runs below 0.4 MPa and needs a compact 1/4in unit. The PC bowl is the standard build, and the semi-auto drain dumps on pressure drop with a manual override for on-demand use. The 40 um element suits general pneumatics; step to the 5 um W element for finer filtration. The PT thread carries an MPa/psi gauge scale if you fit a gauge into the 1/8in connection. The reverse-flow valve is included, and the two units are orderable separately as GAFR200-08 and GAL200-08. For oil-free lines, omit the lubricator and select a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the 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 GAFC20008LNK FAQ
This lower-pressure F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi), with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures, uses a 40 um element, and holds 25 cc in the drain bowl plus 36 cc in the oil bowl. Recommended lubricant is ISO VG 32, and the unit weighs 590 g.
The N after the port code means no gauge is supplied, so you cannot read the set pressure without adding one to the 1/8in gauge connection. The K code indicates a reverse-flow (reflux) valve is fitted, which the catalogue draws as a separate pneumatic symbol. The PC bowl is the standard material option for this body.
