About the Airtac GAFC Air Service Unit GAFC400C10ALWK
This GAFC400C10ALWK is a two-piece F.R.L. combination: a filter and regulator share one body, and a lubricator is joined 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 last, so oil never travels back through the regulator seat. The 3/8in port and 1810 g mass place it in the mid-size class, suited for a machine header or a small multi-station line rather than a single small actuator.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 5 um element trapping fine particles for sensitive valves. A circular gauge is fitted with an MPa/psi scale, and the automatic drain clears condensate from the 100 cc bowl without an operator. The separate 185 cc oil bowl holds ISO VG 32 lubricant, and the metal bowl is a build choice for the surroundings - confirm it suits your environment, as the catalogue gives no material-specific ratings.

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 GAFC400C10ALWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station. The 5 um element protects fine internal clearances, while the lower-pressure range suits delicate actuation that must not see high forces.
Machine tool lubrication
Supply a controlled oil mist to slide ways on a light milling machine. The 185 cc oil bowl keeps the lubricator running for long shifts, and the automatic drain handles condensate from the 100 cc bowl without stopping production.
Test rig air supply
Run a laboratory test fixture that needs clean, regulated air at modest pressure. The metal bowl resists the occasional knock in a busy workshop, and the 5 um element keeps instrument air free of fine particles.
Is the Airtac GAFC Air Service Unit GAFC400C10ALWK the Right Air-Prep Unit?
Choose the GAFC400 body for a 3/8in port with a 6000 L/min flow curve plotted at 0.7 MPa inlet, a step up from the GAFC300's 3500 L/min envelope for larger line demands. The metal bowl (C) is specified here, and the automatic drain (A) suits unattended operation or wet lines. The lower-pressure type (L) tops out at 0.4 MPa, so if the machine may ever need more than that, this is the wrong part - select the standard type instead. The 5 um element (W) filters finer than the standard 40 um but needs more frequent service, and the reverse-flow (reflux) valve (K) is fitted as an ordering difference. The PT thread carries an MPa/psi gauge scale. Spares are orderable separately as the GAFR400-10 filter & regulator and the GAL400-10 lubricator. 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 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 GAFC400C10ALWK FAQ
The GAFC400C10ALWK is a lower-pressure F.R.L. combination with a 3/8in port, regulating from 0.15 to 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 operates from -5 to 70 C and must not freeze. The drain bowl holds 100 cc and the oil bowl holds 185 cc, with a total weight of 1810 g. Use ISO VG 32 or equivalent lubricant.
The C in the code specifies a metal bowl, which is a build choice for the installation - the catalogue gives no temperature or impact ratings for bowl materials, so confirm it suits your surroundings. The K code means a reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue. The automatic drain (A) clears condensate without an operator, and the 5 um element (W) provides finer filtration than the standard 40 um grade.
