Airtac GAFC Air Service Unit GAFC400C10ALN
The AirTAC Airtac GAFC Air Service Unit GAFC400C10ALN 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 GAFC400C10ALN
This GAFC400C10ALN is a two-piece F.R.L. combination: the filter and regulator share one body, and a lubricator is mounted on the same T-bracket. Air enters the 3/8" port, gets filtered and set to pressure in the first body, then the lubricator adds a controlled oil mist last, downstream of the regulator seat. The metal bowl holds 100 cc of condensate, the oil bowl 185 cc, and the complete unit weighs 1810 g.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a max supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The 40 um element handles standard shop air, and the automatic drain clears water without an operator. No gauge is fitted, so the set pressure cannot be read directly; the 1/4" gauge connection allows a later addition.

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 GAFC400C10ALN Is Used
Precision machining center
Feed a CNC spindle air curtain or tool changer with filtered, regulated air at 0.3 MPa (43 psi), where the lower-pressure range prevents over-pressurizing sensitive components.
Assembly line workstations
Supply a multi-station assembly bench with oil-misted air for pneumatic screwdrivers and small cylinders, using the 185 cc oil bowl to reduce refill frequency across shifts.
Packaging machine actuators
Operate film-sealing jaws and pusher cylinders in a packaging line, where the automatic drain keeps condensate out of the system during humid production runs.
Is the Airtac GAFC Air Service Unit GAFC400C10ALN the Right Air-Prep Unit?
Choose the GAFC400C10ALN when your circuit needs clean, regulated air with oil mist, but only up to 0.4 MPa (58 psi). The metal bowl is specified by the C code, a build choice for environments where you want to confirm compatibility with your surroundings. The automatic drain (A) suits unattended lines, and the 40 um element is the standard grade. The no-gauge option (N) means you need a separate 1/4" gauge if operators must see the setpoint. Spare parts are exactly GAFR400-10 and GAL400-10, both orderable separately. 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 (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 GAFC400C10ALN FAQ
The GAFC400C10ALN 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). The temperature range is -5 to 70 C (unfreeze). It has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and is recommended for use with ISO VG 32 lubricant.
The N after the port code means no gauge is supplied, so the set pressure cannot be read without adding one to the 1/4" connection. The C code specifies a metal bowl; the catalogue gives no material-specific ratings, so confirm it suits your environment. The lower-pressure L type tops out at 0.4 MPa, so if your machine may need more, this is the wrong part.
