About the Airtac GAFC Air Service Unit GAFC300N10LWK
This AirTAC GAFC300N10LWK is a two-piece F.R.L. combination on a T bracket: a filter-regulator body and a lubricator body. The 3/8in port, 5 um element, and lower-pressure range of 0.15-0.4 MPa (20-58 psi) make it a compact choice for precise, low-pressure pneumatic circuits.
The nylon bowl holds 60 cc of condensate, while the oil bowl holds 98 cc, and the whole unit weighs 1020 g. The 5 um element traps fine particles, and the semi-auto plus manual drain gives operators control over condensate removal. Air is filtered and regulated first, then oil mist is added last, so the regulator seat never sees oil.

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 GAFC300N10LWK Is Used
Precision pressure setting
Set a stable 0.3 MPa for a delicate air bearing or a precision grinding spindle where standard 0.9 MPa regulation is too coarse and too high.
Lab pneumatic controls
Feed a small laboratory test rig or a sampling valve system that requires clean, oiled air at a controlled low pressure without over-pressurizing sensitive components.
Low-pressure assembly tools
Power a soft-acting pneumatic clamp or a light-duty parts feeder on an assembly bench, where the 5 um element protects fine orifices in the tooling.
Is the Airtac GAFC Air Service Unit GAFC300N10LWK the Right Air-Prep Unit?
Choose the GAFC300N10LWK when your circuit needs a lower regulated pressure of 0.15-0.4 MPa (20-58 psi) and fine 5 um filtration. The nylon bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your environment. The semi-auto drain dumps on pressure drop, with a manual backup for on-demand use. A circular gauge is fitted, reading MPa/psi for the PT thread. The reverse-flow (reflux) valve is fitted, shown as a separate symbol in the catalogue. If the line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. Spares are orderable as GAFR300-10 and GAL300-10. Max supply of 1.0 MPa leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan your 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 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 GAFR300-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N10LWK 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 oil, has a 60 cc drain bowl and a 98 cc oil bowl, and weighs 1020 g.
The L code sets the 0.15-0.4 MPa range, suited for circuits that must not exceed 0.4 MPa. The W code specifies the 5 um element, which traps finer particles than the standard 40 um, protecting precision valves but requiring more frequent element service.
