About the Airtac GAFC Air Service Unit GAFC400C15ALWK
This AirTAC GAFC400C15ALWK is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure control, then a separate lubricator adds a metered oil mist downstream. The 1/2in port and 1810 g mass place it in the mid-size class, suitable for a machine header feeding several actuators.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 5 um element for finer filtration. The metal bowl (100 cc condensate, 185 cc oil) and automatic drain reduce maintenance visits on wet lines. A circular gauge with MPa/psi scale is fitted, and the reverse-flow valve is included as an ordering option.

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 GAFC400C15ALWK Is Used
Precision machining center
Feed a 1/2in header on a CNC machining center, where the 5 um element protects precision spindle valves and the lower pressure range suits sensitive workholding clamps.
Assembly line lubrication
Supply a multi-station assembly line with filtered, regulated air and a controlled oil mist for pneumatic tools, reducing manual lubrication rounds.
Test bench air supply
Provide clean, low-pressure air to a laboratory test bench with pneumatic actuators, where the 0.4 MPa ceiling prevents over-pressurizing delicate fixtures.
Is the Airtac GAFC Air Service Unit GAFC400C15ALWK the Right Air-Prep Unit?
Choose this GAFC400C15ALWK when your circuit needs 1/2in ports and a regulated band capped at 0.4 MPa (20-58 psi). The metal bowl suits environments where you prefer a non-transparent reservoir; the automatic drain clears condensate without operator action. The 5 um element traps finer particles than the standard 40 um, at the cost of more frequent element service. The PT thread carries an MPa/psi gauge scale. Spare parts are the GAFR400-15 filter-regulator and GAL400-15 lubricator, both orderable separately. If your 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 regulated top, so plan your inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C15ALWK FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It has a 100 cc condensate bowl and a 185 cc oil bowl, weighs 1810 g, and is rated for -5 to 70 C. Use ISO VG 32 lubricant. The 5 um element and automatic drain are fitted, with a circular gauge reading MPa/psi.
The C code specifies a metal bowl, a build choice for the reservoir; the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of material, so confirm it suits your surroundings. The K code adds a reverse-flow (reflux) valve, which the catalogue shows as a separate pneumatic symbol. Both are ordering options that change the unit's configuration.
