About the Airtac GAFC Air Service Unit GAFC300N10LNK
This GAFC300N10LNK is a two-piece F.R.L. combination: the first body houses the filter and regulator together, and the second body is the lubricator. Air enters the 3/8" port, gets filtered to 40 um, and is regulated down to the lower pressure band of 0.15-0.4 MPa (20-58 psi) before the lubricator adds a metered oil mist last.
The nylon bowl holds 60 cc of condensate and the oil bowl holds 98 cc, with the whole assembly weighing 1020 g. No gauge is supplied with this model, so the 1/8" gauge connection is available if you want to add one later. The reverse-flow (reflux) valve is fitted, and the unit is rated for -5 to 70 C with ISO VG 32 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 GAFC300N10LNK Is Used
Precision pressure control
Feed a precision pneumatic regulator or a sensitive control valve that needs a stable 0.15-0.4 MPa supply, where the lower range prevents over-pressurizing delicate components.
Assembly line workstations
Power a small assembly fixture or a single-axis actuator on a workbench, where the 3/8" port and 1020 g weight suit a compact machine setup without over-sizing the air prep.
Laboratory air supply
Supply filtered and lubricated air to a lab test rig or a small pneumatic cylinder used in experiments, where the lower pressure range protects sensitive test equipment.
Is the Airtac GAFC Air Service Unit GAFC300N10LNK the Right Air-Prep Unit?
Choose this GAFC300N10LNK when your circuit needs the lower pressure range of 0.15-0.4 MPa (20-58 psi) and you want the nylon bowl option. The semi-auto drain dumps condensate each time pressure drops, while the manual drain gives you on-demand control. Since there is no gauge fitted, plan to add one at the 1/8" connection if operators need to read the set pressure. The 40 um element handles standard shop air, and the PT thread matches common piping. The two units are separately orderable as GAFR300-10 and GAL300-10, so you can replace just the damaged section. If your line must stay oil-free, skip the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, giving you a comfortable margin for supply fluctuations.
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 GAFC300N10LNK FAQ
The GAFC300N10LNK 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 temperatures from -5 to 70 C and uses ISO VG 32 oil. The drain bowl holds 60 cc and the oil bowl holds 98 cc, with a total weight of 1020 g. The element is 40 um and the port is 3/8".
The N after the port code means no gauge is supplied with this unit. The gauge connection is 1/8", so you can add a circular gauge later if you need to read the set pressure. The N before the port code indicates the bowl is made of nylon, which is a material choice for your environment - confirm it suits your surroundings since the catalogue gives no specific material performance data.
