About the Airtac GAFC Air Service Unit GAFC300N10L
The GAFC300N10L is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. Air enters the 3/8" port, gets filtered and set to pressure in the first body, then the lubricator adds a metered oil mist downstream. This lower-pressure version regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element catching solids and moisture.
The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, giving this 1020 g unit a practical service rhythm for medium-duty lines. The circular gauge reads in MPa/psi, and the semi-auto drain dumps on pressure drop while the manual drain works on demand. With a 1.0 MPa max supply, there is about 0.6 MPa of headroom above the 0.4 MPa top of the range.

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 GAFC300N10L Is Used
Low-Pressure Assembly Stations
Feed a delicate press-fit or insertion station that runs at 0.3 MPa to avoid damaging small components. The 0.15-0.4 MPa band gives fine control for force-sensitive operations.
Laboratory Air Supply
Supply filtered, regulated air to a lab bench with pneumatic actuators or valves that must stay below 0.4 MPa. The 40 um element and lubricator keep moving parts working smoothly.
Paint or Coating Lines
Regulate atomizing air for low-pressure spray equipment where exceeding 0.4 MPa would over-atomize the coating. The 60 cc drain bowl handles moisture from wet supply lines.
Is the Airtac GAFC Air Service Unit GAFC300N10L the Right Air-Prep Unit?
Choose the GAFC300N10L when your circuit needs regulated air below 0.4 MPa (58 psi) and a 3/8" port fits the flow. The nylon bowl is a build choice - confirm it suits your environment, as the catalogue gives no material-specific ratings. The semi-auto drain clears condensate on each pressure drop, with a manual backup for scheduled maintenance. The 40 um element handles general shop air; step to the W option for 5 um filtration if you feed precision valves. The PT thread carries a MPa/psi gauge scale, so operators read the same units as the fittings. If the line must stay oil-free, omit the lubricator and choose a plain GAFR300-10 filter-regulator instead. Spares are the GAFR300-10 and GAL300-10, both orderable separately. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the regulated range.
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 GAFC300N10L FAQ
The GAFC300N10L 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). Temperature range is -5 to 70 C. It has a 60 cc drain bowl and 98 cc oil bowl, weighs 1020 g, and uses ISO VG 32 lubricant. The element grade is 40 um.
The L code sets the regulation ceiling at 0.4 MPa instead of the standard 0.9 MPa. This suits circuits that must never exceed 0.4 MPa, such as delicate gripping or low-force positioning. If your machine might need more pressure later, the standard S type would be the safer choice.
