About the Airtac GAFC Air Service Unit GAFC20008LNWK
This AirTAC GAFC20008LNWK is a two-piece F.R.L. combination: the filter and regulator share one body, and a lubricator is mounted on the same T-bracket. With a 1/4in port and a 5 um element, it cleans and regulates air to a lower pressure band of 0.15-0.4 MPa (20-58 psi), then adds a controlled oil mist. The 590 g unit is sized for small machines and single actuators, not for supporting heavy piping.
The 25 cc condensate bowl and 36 cc oil bowl set the service rhythm; the 5 um element traps finer particles than the standard 40 um grade, so expect to service it more often. No gauge is fitted, but the 1/8" gauge connection is there if you add one. The reverse-flow (reflux) valve is included, and the semi-auto drain dumps condensate each time pressure drops, with a manual override for on-demand draining.

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 GAFC20008LNWK Is Used
Precision valve control
Feed a small pneumatic valve manifold on a benchtop assembly station. The 5 um element protects fine internal passages, and the lower pressure range suits delicate actuation.
Single jig clamping
Power a compact clamping fixture on a drill press or workbench. The 1/4in port and 590 g weight let it mount directly on the machine frame without extra support.
Lab air supply
Supply clean, regulated air to a small laboratory setup that needs a gentle, consistent pressure. The 5 um filtration and lower range protect sensitive instruments from surges.
Is the Airtac GAFC Air Service Unit GAFC20008LNWK the Right Air-Prep Unit?
Choose this GAFC20008LNWK when your circuit needs fine filtration and a lower regulated pressure, and you want the option of a reverse-flow valve. The 1/4in port suits small cylinders and jigs; step up to the GAFC300 (3/8in or 1/2in port, 3500 L/min envelope at 0.7 MPa inlet) for more flow. The 5 um element is for precision valves or instrument air, but it will clog faster than the 40 um standard, so weigh that trade-off. The PC bowl is the build choice here; confirm it suits your environment. The semi-auto and manual drains are both fitted, so you can rely on the automatic dump or open it by hand. No gauge is supplied, so plan to read pressure with a separate gauge on the 1/8" connection. Spare parts are the GAFR200-08 filter-regulator and the GAL200-08 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so you have room to feed it from a higher-pressure line.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 590 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 GAFR200-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC20008LNWK FAQ
The pressure range is 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 operates from -5 to 70 C and must not freeze. The condensate bowl holds 25 cc, the oil bowl 36 cc, and the unit weighs 590 g. Use ISO VG 32 oil in the lubricator. The element is 5 um and the port is 1/4in.
The N in the code after the port means no gauge is supplied. This keeps the unit compact and reduces cost. If you need to read the set pressure, you can add a gauge to the 1/8" connection on the body, which is standard for the GAFC200 size.
