About the Airtac GAFC Air Service Unit GAFC300N08ALWK
This AirTAC GAFC300N08ALWK is an F.R.L. combination that pairs a filter-regulator with a lubricator on a single T-bracket, so the air is cleaned, set to pressure, and then oil-misted in one compact two-piece assembly. The 1/4in port and 1020 g mass place it in the GAFC300 size class, which suits small machine stations and single actuator feeds.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), with a 5 um element trapping fine particles before the air reaches the lubricator. The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, and the automatic drain clears water without an operator, making this a low-attention unit for a wet or remote line.

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 GAFC300N08ALWK Is Used
Precision Valve Control
Feed a 5 um-filtered, regulated air supply to a precision pneumatic valve on a small assembly station, where the lower 0.4 MPa range prevents over-pressuring delicate actuators.
Wet Line Condensate
Mount on a machine header in a humid plant where the automatic drain clears water from the 60 cc bowl without an operator, keeping a single shift running unattended.
Small Jig Actuation
Power a bench-mounted jig or clamping fixture with a 1/4in line, using the 98 cc oil bowl to lubricate the cylinder while the 5 um element protects its seals.
Is the Airtac GAFC Air Service Unit GAFC300N08ALWK the Right Air-Prep Unit?
Choose the 1/4in port for a small jig or a single cylinder; step up to the GAFC400's 3/8in port and 100 cc bowl if the line feeds several actuators. The nylon bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C rating are the same for PC, metal, or nylon, so confirm the material suits your environment. The automatic drain handles condensate on its own, while the 5 um element catches finer particles than the standard 40 um, at the cost of more frequent element changes. The fitted circular gauge reads in MPa and psi on the PT thread, and the reverse-flow valve is present as an ordering option. Spares are GAFR300-08 and GAL300-08, both orderable separately. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above this unit's 0.4 MPa top setting, so plan the 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 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 GAFC300N08ALWK FAQ
The GAFC300N08ALWK 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 60 cc drain bowl and a 98 cc oil bowl, weighs 1020 g, and is rated for -5 to 70 C. The recommended lubricant is ISO VG 32, and the 5 um element filters the air before it reaches the lubricator.
The L type code sets the regulator to 0.15-0.4 MPa instead of the standard 0.15-0.9 MPa, which suits applications that need a gentle, consistent supply without the risk of over-pressurization. If your machine may ever require more than 0.4 MPa, this is the wrong part - choose the S type instead. The 1.0 MPa max supply gives about 0.6 MPa of headroom above the 0.4 MPa top setting.
