Airtac GAFC Air Service Unit GAFC400N10ALN
The AirTAC Airtac GAFC Air Service Unit GAFC400N10ALN 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 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC400N10ALN
This GAFC400N10ALN is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 3/8in port and 1810 g mass put it in the mid-size class, suited to a machine header feeding several actuators rather than a single small cylinder.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), with a 40 um element and an automatic drain. The nylon bowl holds 100 cc of condensate and the oil bowl 185 cc. No gauge is fitted, so the 1/4in gauge connection is available if you add one. The lubricator adds oil mist after regulation, so the line is not oil-free as supplied.

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 GAFC400N10ALN Is Used
Precision pressure setting
Set a stable 0.3 MPa supply for a small indexing table or a light press, where the lower-pressure range gives finer adjustment than a standard 0.9 MPa regulator.
Wet line condensate control
Feed a multi-spindle drilling station where the automatic drain clears water from the 100 cc bowl, reducing manual checks on a line with high humidity.
Lubricated actuator feed
Supply oil-misted air to a pair of guided cylinders on a packaging machine, with the 185 cc oil bowl supporting longer runs between refills.
Is the Airtac GAFC Air Service Unit GAFC400N10ALN the Right Air-Prep Unit?
Choose the GAFC400N10ALN when your circuit needs a regulated 0.15-0.4 MPa (20-58 psi) band and you want the automatic drain to handle condensate without operator attention. The nylon bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your surroundings. The 40 um element handles general shop air, and the PT thread with MPa/psi gauge scale matches common local fittings. The two units are orderable separately as GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, you have 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 (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 GAFC400N10ALN FAQ
The pressure range is 0.15-0.4 MPa (20-58 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The unit weighs 1810 g and has a 3/8in port.
The N after the port code means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a pressure gauge later if you need to read the setpoint. Without one, the regulated pressure cannot be verified visually.
