About the Airtac GAFC Air Service Unit GAFC40010LNK
This GAFC40010LNK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The air is cleaned and set to pressure in the first unit, then the lubricator adds a controlled oil mist downstream, so oil never travels back through the regulator seat. With a 3/8in port and 1810 g mass, this size class suits mid-size machine headers rather than small jigs.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um filter element and both semi-auto and manual drains fitted. The 100 cc condensate bowl and 185 cc oil bowl set the service rhythm, and the reverse-flow valve is included. No gauge is supplied, but the 1/4in gauge connection is ready if you add one.

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 GAFC40010LNK Is Used
Precision Assembly Stations
Feed a 3/8in line to a semi-automatic assembly press where operators need a stable, lower pressure for delicate part placement without over-stroking cylinders.
Machine Tool Lubrication
Supply a metered oil mist to a small CNC spindle or slideway lubrication system, keeping moving parts coated while the regulated air stays below 0.4 MPa.
Test Rig Air Supply
Run a bench-top pneumatic test fixture that requires clean, regulated air at a fixed low pressure, with the 100 cc bowl handling condensate from a humid shop line.
Is the Airtac GAFC Air Service Unit GAFC40010LNK the Right Air-Prep Unit?
Choose this GAFC40010LNK when your circuit needs a 3/8in port and a regulated ceiling of 0.4 MPa. The L type is a deliberate trade-off: it caps the working range at 0.4 MPa (20-58 psi), so if the machine may ever require more pressure, step to the standard S type instead. The PC bowl is the default build; the catalogue lists no material-specific ratings, so confirm it suits your environment before ordering. The semi-auto drain dumps condensate on each pressure drop, while the manual drain gives on-demand control. The 40 um element handles general shop air, and the reverse-flow valve is fitted as specified. For spares, order the GAFR400-10 filter-regulator and GAL400-10 lubricator separately.
With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range, so plan your 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 GAFC40010LNK FAQ
This F.R.L. combination operates on air with a lower-pressure range of 0.15-0.4 MPa (20-58 psi). Maximum supply pressure is 1.0 MPa (145 psi), and proof pressure is 1.5 MPa (215 psi). It works in temperatures from -5 to 70 C and uses ISO VG 32 oil. The condensate bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 1810 g.
The N in the code means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later if you need to read the set pressure. Until then, the regulated output cannot be visually verified without an external gauge.
