About the Airtac GAFC Air Service Unit GAFC300N10LN
This AirTAC GAFC300N10LN is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared bracket. The 3/8in port size and 1020 g mass place it in the mid-range class, suitable for feeding a small machine station or a bank of actuators.
Air enters the filter-regulator where solids and moisture are removed and pressure is set to 0.15-0.4 MPa (20-58 psi), then the lubricator adds a metered oil mist downstream. The 40 um element handles standard shop air, while the 60 cc condensate bowl and 98 cc oil bowl define the service interval. No gauge is supplied; the 1/8in gauge connection allows a later addition.

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 GAFC300N10LN Is Used
Precision pressure setting
Set a delicate clamping pressure on a CNC fixture where the lower 0.4 MPa ceiling prevents over-force on thin-walled parts.
Gentle part handling
Feed a pick-and-place unit that moves fragile electronic components, using the 0.15-0.4 MPa band to keep gripper force low.
Laboratory air supply
Provide filtered and lubricated air to a test bench running small pneumatic cylinders at controlled low pressures.
Is the Airtac GAFC Air Service Unit GAFC300N10LN the Right Air-Prep Unit?
The GAFC300N10LN uses the lower-pressure regulator, topping out at 0.4 MPa (58 psi) - if your line may ever need more than that, select the standard S type instead. The nylon bowl is named as a build choice; the shared specification of 1.0 MPa max and -5 to 70 C applies, so confirm the material suits your environment. Both a semi-auto drain (dumps on pressure drop) and a manual drain are fitted, giving you two ways to clear the 60 cc bowl. The 5 um element option (W) is available for finer filtration at the cost of more frequent service. Replacement units are orderable separately as GAFR300-10 and GAL300-10. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the 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 GAFC300N10LN FAQ
This lower-pressure unit 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). Temperature range is -5 to 70 C. It has a 60 cc drain bowl and 98 cc oil bowl, weighs 1020 g, and requires ISO VG 32 lubricant.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so you can add a circular gauge later to read the set pressure. Without one, the outlet pressure cannot be read directly on the unit.
