About the Airtac GAFC Air Service Unit GAFC40010ALW
This GAFC40010ALW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. The 3/8in port and 1810 g mass place it in the mid-range size class, suited for a machine header feeding several actuators. Air is filtered and set to pressure in the first body, then the lubricator adds a controlled oil mist last, so oil never travels back through the regulator seat.
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. The automatic drain clears condensate from the 100 cc bowl without an operator, while the 185 cc oil bowl sets the service interval for topping up ISO VG 32 lubricant. A circular gauge is fitted, reading MPa and psi on the default PT thread scale.

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 GAFC40010ALW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging machine, where the 5 um element protects fine internal passages from particle wear.
Machine tool lubrication
Supply a controlled oil mist to slide ways and spindles on a CNC lathe, with the lower pressure range protecting sensitive metering units.
Test rig air supply
Provide filtered, regulated, lubricated air to a laboratory test bench with multiple small actuators, where the 0.4 MPa ceiling matches the rig's design pressure.
Is the Airtac GAFC Air Service Unit GAFC40010ALW the Right Air-Prep Unit?
Choose the GAFC40010ALW when your line needs fine filtration and a regulated ceiling of 0.4 MPa, not the standard 0.9 MPa. The 5 um element suits precision pneumatic controls, though it will need more frequent service than a 40 um element. The automatic drain is the right call for unattended operation or wet supply lines, removing condensate from the 100 cc bowl without manual intervention. The PC bowl is the standard build; confirm it suits your environment, as the catalogue gives no material-specific chemical or temperature data. The circular gauge reads MPa and psi, matching the PT thread. For a line that must stay oil-free, omit the lubricator and select a plain GAFR400-10 filter-regulator instead. Spare parts are the GAFR400-10 and GAL400-10, 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, so plan your 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 GAFC40010ALW FAQ
The GAFC40010ALW 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 handles temperatures from -5 to 70 C, uses ISO VG 32 lubricant, and weighs 1810 g. The drain bowl holds 100 cc and the oil bowl holds 185 cc.
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. This suits applications with sensitive components that must not see higher pressures, such as precision regulators or delicate actuators. If your machine may ever need more than 0.4 MPa, this is the wrong part.
