About the Airtac GAFC Air Service Unit GAFC300N08ALW
The GAFC300N08ALW 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. Air enters the 1/4in port, passes through the 5 um element, and is regulated down to the lower 0.15-0.4 MPa (20-58 psi) band before the lubricator meters oil mist into the stream last.
This nylon-bowl unit carries a 60 cc condensate bowl and a 98 cc oil bowl, weighing 1020 g. The automatic drain clears collected water without operator attention, while the fitted circular gauge reads in MPa and psi. The catalogue flow curve plots to 3500 L/min at 0.7 MPa inlet, useful for relative sizing rather than as a rated capacity.

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 GAFC300N08ALW Is Used
Precision Fixture Clamping
Feed a small work-holding fixture on a benchtop assembly station, where the 1/4in port and lower pressure range protect delicate parts from over-clamping.
Laboratory Air Supply
Supply filtered, regulated air to a lab bench pneumatic actuator or test rig, with the 5 um element keeping fine particles away from sensitive valves.
Light Packaging Line
Run a single cylinder on a light packaging or labeling machine, where the automatic drain reduces maintenance on a line that runs intermittently.
Is the Airtac GAFC Air Service Unit GAFC300N08ALW the Right Air-Prep Unit?
Choose the GAFC300N08ALW when your circuit needs a modest 1/4in port with a lower regulated ceiling of 0.4 MPa. The nylon bowl is specified by the N code, and the automatic drain suits lines where condensate builds up between visits. The 5 um element traps finer particles than the standard 40 um grade, though it will need more frequent service. The default PT thread carries an MPa/psi gauge scale, and the K option adds a reverse-flow valve if you need it. Spare parts are the GAFR300-08 filter-regulator and the GAL300-08 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.
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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N08ALW 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 works in -5 to 70 C temperatures, uses ISO VG 32 lubricant, has a 60 cc drain bowl and 98 cc oil bowl, and weighs 1020 g.
The L code specifies the lower-pressure type, which tops out at 0.4 MPa instead of the standard 0.9 MPa. This suits applications needing gentle, consistent pressure below 0.4 MPa. If your machine may ever require more than 0.4 MPa, choose the standard S type instead, as this unit cannot be adjusted beyond its rated ceiling.
