About the Airtac GAFC Air Service Unit GAFC300N08AL
This AirTAC GAFC300N08AL is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. Air is cleaned and set to pressure in the first body, then the lubricator adds a metered oil mist downstream, so oil never travels back through the regulator seat. With a 1/4in port and a 1020 g mass, it suits compact machine builds where panel space is limited.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 40 um element handles standard shop air. The nylon bowl is specified by the N code, and the automatic drain clears condensate without an operator. The circular gauge is fitted and reads in MPa/psi for the default PT thread.

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 GAFC300N08AL Is Used
Precision valve actuation
Feeds a single pneumatic valve manifold on a small assembly station, where the lower 0.4 MPa ceiling protects sensitive actuators from over-pressure.
Light conveyor controls
Supplies a short conveyor section's air cylinders and sensors, with the automatic drain keeping condensate out of the control line during humid shifts.
Test bench air supply
Powers a lab test fixture that needs clean, regulated air at low pressure, with the lubricator adding oil mist for the fixture's moving parts.
Is the Airtac GAFC Air Service Unit GAFC300N08AL the Right Air-Prep Unit?
Choose the GAFC300 body for 1/4in or 3/8in ports with a 60 cc condensate bowl and 98 cc oil bowl, giving a good balance between service interval and footprint. The nylon bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your environment. The automatic drain is ideal for unattended lines, while the lower-pressure range caps at 0.4 MPa - if your machine may ever need more, select the standard type instead. The gauge reads MPa/psi with PT threads, and the 40 um element is standard. Spare parts are orderable as GAFR300-08 and GAL300-08.
Max supply at 1.0 MPa leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan your inlet pressure carefully if you need the full regulated band.
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 GAFC300N08AL FAQ
This lower-pressure unit operates from 0.15 to 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 from -5 to 70 C and must not freeze. The drain bowl holds 60 cc and the oil bowl 98 cc, with a total weight of 1020 g. Use ISO VG 32 lubricant.
The L indicates the lower-pressure type, regulating from 0.15 to 0.4 MPa instead of the standard 0.15 to 0.9 MPa. This suits applications that need a firm ceiling on outlet pressure, but if your line may require more than 0.4 MPa, you would need the standard S type instead.
