About the Airtac GAFC Air Service Unit GAFC40010ALWK
The GAFC40010ALWK is an F.R.L. combination built as two units on one T-shape bracket: the filter and regulator share a single body, and the lubricator adds a metered oil mist downstream. This 3/8in version regulates from 0.15 to 0.4 MPa (20-58 psi) and filters to 5 um, with a circular gauge reading MPa/psi.
The 100 cc condensate bowl and 185 cc oil bowl set the service rhythm, while the 1810 g mass calls for a proper panel or frame mount rather than tubing support. The automatic drain clears water without an operator, and the reverse-flow valve is fitted as an ordering option. The lower-pressure range makes this unit a poor fit if the machine may ever need more than 0.4 MPa.

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 GAFC40010ALWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station where the 5 um element protects fine internal clearances and the 0.4 MPa ceiling matches the valve spec.
Packaging line actuators
Run a row of short-stroke actuators on a carton erector or case packer, where the automatic drain keeps condensate out of the line during long unattended shifts.
Lab instrument air
Supply a test fixture or lab instrument that needs clean, regulated air at modest pressure, with the lower range preventing accidental over-pressurization of sensitive parts.
Is the Airtac GAFC Air Service Unit GAFC40010ALWK the Right Air-Prep Unit?
Choose the GAFC40010ALWK when your line needs 3/8in ports and a regulated ceiling of 0.4 MPa. The L type tops out there, so confirm the downstream demand stays below that figure. The 5 um element traps finer particles than the standard 40 um but will need more frequent service. The PC bowl is the default build; confirm it suits your environment, since the catalogue gives no material-specific ratings. The automatic drain suits unattended operation, and the PT thread carries a gauge scaled in MPa/psi. The reverse-flow valve is fitted per the K code. Spares are the GAFR400-10 filter-regulator and GAL400-10 lubricator, both orderable 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.
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 GAFC40010ALWK FAQ
This F.R.L. combination operates on air 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). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The L in the code specifies the lower-pressure type, regulating from 0.15 to 0.4 MPa instead of the standard 0.15 to 0.9 MPa. The K code adds a reverse-flow valve, which the catalogue shows as a separate pneumatic symbol. This unit also carries a 5 um element and an automatic drain, so it is built for finer filtration and unattended operation at modest pressures.
