About the Airtac GAFC Air Service Unit GAFC40010ALNK
This AirTAC GAFC40010ALNK is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is mounted separately on a T-bracket with quick clamps. Air is cleaned and set to pressure in the first body, then a metered oil mist is added downstream, so oil never passes back through the regulator seat. The 3/8in port and 1810 g mass place it in the mid-size class, needing a proper panel or frame mount rather than support from the tubing.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element and an automatic drain that clears condensate without an operator. The 100 cc condensate bowl and 185 cc oil bowl define the service interval, and the 1/4in gauge connection is ready if a gauge is added later. The reverse-flow (reflux) valve is fitted, and the catalogue shows it as a separate pneumatic symbol.

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 GAFC40010ALNK Is Used
Precision pressure setting
Set a lathe's air chuck or a parts feeder to a stable 0.3 MPa, knowing the lower-pressure regulator holds the setpoint as shop supply varies. The 40 um element keeps fine swarf out of the pilot valves.
Light conveyor lubrication
On a small assembly conveyor, the lubricator meters ISO VG 32 oil to cylinder seals while the 100 cc bowl collects condensate from the compressor line. The automatic drain clears water without stopping the line.
Packaging machine air prep
Feed a carton erector's pneumatic sensors and actuators with filtered, regulated, oil-misted air. The 185 cc oil bowl supports a full shift between refills, and the reverse-flow valve is fitted for the machine's circuit.
Is the Airtac GAFC Air Service Unit GAFC40010ALNK the Right Air-Prep Unit?
Choose this GAFC40010ALNK when your line needs 3/8in ports and a regulated band capped at 0.4 MPa (20-58 psi). The PC bowl is the standard build; confirm it suits your surroundings, as the catalogue gives no material-specific resistance data. The automatic drain is ideal for unattended operation, and the 40 um element handles general shop air. The no-gauge version leaves a 1/4in connection for a field-installed gauge, and the PT thread carries an MPa/psi scale if you add one. Spares are orderable as GAFR400-10 and GAL400-10, so a clogged element or damaged bowl does not mean replacing the whole assembly. If the line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the range, so plan the inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 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 GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC40010ALNK FAQ
This lower-pressure F.R.L. combination works 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). It operates from -5 to 70 C and must not freeze. The 100 cc condensate bowl and 185 cc oil bowl are fitted, the unit weighs 1810 g, and the recommended lubricant is ISO VG 32 or equivalent.
The N in the code means no gauge is supplied, so you cannot read the set pressure without adding one. The GAFC400 body has a 1/4in gauge connection, and with the default PT thread, a field-added gauge would read in MPa and psi. The reverse-flow valve is fitted per the K code.
