Airtac GAFC Air Service Unit GAFC40010LNWK
The AirTAC Airtac GAFC Air Service Unit GAFC40010LNWK 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 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC40010LNWK
This AirTAC GAFC40010LNWK is an F.R.L. combination where the filter and pressure regulator share one body, and a lubricator is mounted alongside on a T-bracket with quick clamps. It handles a 3/8in port and weighs 1810 g, placing it in the mid-size class for machine-level air preparation. The 5 um element traps fine particles for sensitive valves, while the lower-pressure regulator tops out at 0.4 MPa (20-58 psi).
Air passes through the filter-regulator first, then the lubricator adds a controlled oil mist downstream, so oil never travels back through the regulator seat. The 100 cc condensate bowl and 185 cc oil bowl set the service rhythm, and the semi-auto drain dumps on pressure drops while the manual drain works on demand. No gauge is fitted, so the 1/4in gauge port on the body is where a gauge would go if you need to read the set pressure.

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 GAFC40010LNWK Is Used
Low-Pressure Assembly Tools
Feed a 3/8in line to pneumatic screwdrivers or torque tools on an assembly bench, where the 0.4 MPa ceiling prevents over-torquing delicate fasteners.
Lab Air Circuits
Supply filtered, lubricated air to a lab fixture that cycles small cylinders at controlled low pressure, with the 5 um element protecting fine orifices in solenoid valves.
Packaging Line Sensors
Run a low-pressure air circuit for sensing and light actuation on a packaging machine, where the 100 cc bowl handles condensate between scheduled maintenance checks.
Is the Airtac GAFC Air Service Unit GAFC40010LNWK the Right Air-Prep Unit?
Choose this GAFC40010LNWK when your line needs 3/8in ports and a regulated ceiling of 0.4 MPa, not the standard 0.9 MPa. The L type suits low-pressure circuits, but if the machine may ever need more than 0.4 MPa, step up to the S type instead. The 5 um element filters finer than the standard 40 um, trading more frequent element service for cleaner air to precision components. The PC bowl is the default build; confirm it suits your environment since the catalogue gives no material-specific ratings. The reverse-flow (reflux) valve is fitted per the K code, and the PT thread carries the MPa/psi gauge scale if you add a gauge later. Spare parts are 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 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 GAFC40010LNWK FAQ
The GAFC40010LNWK operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures and needs ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 1810 g.
The N after the port code means no gauge is supplied, so you cannot read the set pressure without adding one to the 1/4in gauge connection. The K code means a reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol.
