About the Airtac GAFC Air Service Unit GAFC20008LNW
This GAFC20008LNW is a two-piece F.R.L. combination where the filter and regulator share one body, and the lubricator is mounted separately on a T-bracket. It handles a 1/4in port and regulates air down to a lower pressure band of 0.15-0.4 MPa (20-58 psi), with a 5 um element for finer filtration.
The 25 cc condensate bowl and 36 cc oil bowl are both transparent polycarbonate, and the unit weighs 590 g. The semi-auto drain releases condensate when pressure drops, while the manual drain offers on-demand control. No gauge is fitted, so the 1/8in gauge connection is available if you add one later.

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 GAFC20008LNW Is Used
Precision valve control
Feed a 5 um filtered, lower-pressure air supply to a precision pneumatic valve on a small assembly fixture, where the 0.4 MPa ceiling prevents over-actuation.
Bench-top pneumatic press
Power a small bench press cylinder that needs a regulated 0.15-0.4 MPa range, with the 25 cc bowl handling condensate from intermittent use.
Lab air preparation
Prepare instrument air for a lab test rig that requires fine 5 um filtration and a lower pressure setting, with the semi-auto drain managing moisture between experiments.
Is the Airtac GAFC Air Service Unit GAFC20008LNW the Right Air-Prep Unit?
Choose this GAFC20008LNW when your application needs a lower regulated pressure ceiling of 0.4 MPa, not the standard 0.9 MPa. The 5 um element suits precision valves or instrument air, though it will need more frequent service than a 40 um element. The PC bowl is the standard build; confirm it suits your environment, as the catalogue provides no material-specific resistance data. The semi-auto plus manual drain pair covers both automatic and on-demand condensate removal, and the PT thread with no gauge means you will need to add one via the 1/8in connection to read set pressure. For oil-free lines, omit the lubricator and choose a plain GAFR200-08 filter-regulator instead. Spares for this unit are the GAFR200-08 filter-regulator and GAL200-08 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, so plan your inlet pressure accordingly.
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 GAFC20008LNW FAQ
This F.R.L. combination 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 has a 25 cc drain bowl and 36 cc oil bowl, weighs 590 g, and is rated for -5 to 70 C. Use ISO VG 32 lubricant in the oil bowl.
The N in the code means no gauge is supplied. The GAFC200 body has a 1/8in gauge connection, so you can add a compatible gauge to read the set pressure. Without one, you cannot visually confirm the regulated output.
