About the Airtac GAFC Air Service Unit GAFC300N08LNW
This GAFC300 F.R.L. combination pairs a filter-regulator body with a lubricator on a shared T-bracket, so the air is cleaned, set to a lower pressure, then oil-misted in the last stage. With a 1/4in port and a 5 um element, it suits precision circuits where fine filtration matters more than high flow.
The lower-pressure regulator tops out at 0.4 MPa (20-58 psi), and the 60 cc condensate bowl plus 98 cc oil bowl set the service rhythm. At 1020 g, it needs a proper panel mount rather than tubing support. The nylon bowl is specified by the N code, and the catalogue gives no material-specific durability data, so confirm it suits your environment before ordering.

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 GAFC300N08LNW Is Used
Low-Pressure Assembly Tools
Feed a pneumatic screwdriver or torque tool on an assembly bench where the supply is 0.4 MPa and fine particle control protects the tool's internal vanes.
Lab Air Circuits
Supply a small laboratory fixture or test jig that runs on regulated low pressure, with the 5 um element keeping instrument-grade air clean.
Light Duty Actuation
Run a single small-bore cylinder or a compact indexing table where the lower pressure range matches the actuator's rating and the 60 cc bowl handles light condensate loads.
Is the Airtac GAFC Air Service Unit GAFC300N08LNW the Right Air-Prep Unit?
Choose the GAFC300N08LNW when your line needs 1/4in ports and a regulated ceiling of 0.4 MPa (20-58 psi) - below that, the Standard S type offers 0.15-0.9 MPa if you might ever need more. The 5 um element traps finer particles than the standard 40 um, at the cost of more frequent element service. The semi-auto drain dumps condensate on each pressure drop, while the manual drain gives on-demand control. No gauge is fitted, so the set pressure cannot be read without adding one to the 1/8in gauge connection. The nylon bowl is a build choice, not a performance upgrade; the common specification applies to all bowl materials. Spares are orderable as GAFR300-08 and GAL300-08. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so the regulator has ample inlet headroom for stable lower-pressure output.
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 GAFC300N08LNW FAQ
The working 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 drain bowl holds 60 cc and the oil bowl 98 cc. Recommended lubricant is ISO VG 32. The unit weighs 1020 g and has a 1/4in port.
The N after the port code means no pressure gauge is supplied. The gauge connection on the GAFC300 body is 1/8in, so you can add a gauge later if needed. Without one, the set pressure cannot be read directly on the unit, so plan to add a gauge if operators need to verify the 0.15-0.4 MPa setting.
