Airtac GAFC Air Service Unit GAFC300C10LN
The AirTAC Airtac GAFC Air Service Unit GAFC300C10LN is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC300C10LN
This GAFC300 F.R.L. combination pairs a filter-regulator with a lubricator on a single T-bracket, so you get three functions from two pieces. The 3/8in port and 1020 g mass place it in the mid-size class, and the metal bowl is specified for this build. Its lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), with a 40 um element protecting downstream components.
The filter and regulator share one body, so air is cleaned and set to pressure before the lubricator adds a metered oil mist last. The 60 cc condensate bowl and 98 cc oil bowl define the service interval, while the 1/8in gauge connection lets you add a pressure readout if needed. With no gauge fitted, the set pressure cannot be read without adding one.

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 GAFC300C10LN Is Used
Low-Pressure Jig Fixturing
Feed a clamping jig on a benchtop assembly station where the regulator is set to 0.3 MPa to avoid crushing delicate parts. The metal bowl suits a shop floor with occasional coolant splash.
Paint Booth Air Lines
Supply a low-pressure line to a paint booth's atomizing nozzles, where the 0.4 MPa ceiling keeps the spray pattern consistent. The 40 um element traps particles before they reach the nozzle.
Test Bench Air Supply
Run a pneumatic test bench that needs a stable low-pressure source for calibration fixtures. The 60 cc drain bowl handles condensate from a humid compressor line, and the manual drain lets the operator purge on schedule.
Is the Airtac GAFC Air Service Unit GAFC300C10LN the Right Air-Prep Unit?
Choose the GAFC300C10LN when your line needs a 3/8in port and a lower regulated pressure, with a metal bowl and no gauge. The L type tops out at 0.4 MPa, so if the machine may ever need more, this is the wrong part. The semi-auto drain dumps condensate on each pressure drop, and the manual drain works on demand. Spare units are orderable separately as the GAFR300-10 filter & regulator and the GAL300-10 lubricator. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure carefully.
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 GAFC300C10LN FAQ
This F.R.L. combination 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 has a 3/8in port, 40 um element, 60 cc drain bowl, 98 cc oil bowl, and weighs 1020 g. The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32.
The C code specifies a metal bowl, a build choice you should confirm suits your surroundings, as the catalogue gives no material-specific ratings. The N after the port means no gauge is supplied, so you cannot read the set pressure without adding one to the 1/8in gauge connection.
