Airtac GAFC Air Service Unit GAFC300N10ASK
The AirTAC Airtac GAFC Air Service Unit GAFC300N10ASK 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 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC300N10ASK
This AirTAC GAFC300N10ASK is an F.R.L. combination where the filter and pressure regulator share one body, and a lubricator is mounted alongside on a T-bracket with quick clamps. 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 a few actuators. Air enters, solids and moisture are removed, pressure is set to the 0.15-0.9 MPa (20-130 psi) band, and a metered oil mist is added last, downstream of the regulator seat.
The 60 cc condensate bowl and 98 cc oil bowl set the service rhythm; the automatic drain clears water without an operator, which suits lines that run unattended. The nylon bowl is specified by the N code, and the common specification of 1.0 MPa max and -5 to 70 C applies. A circular gauge is fitted, reading MPa/psi for the PT thread, and the reverse-flow (reflux) valve is included as an ordering difference.

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 GAFC300N10ASK Is Used
Precision Jig Fixtures
Feed a 3/8in line to a precision drilling jig where consistent clamping pressure and a light oil mist keep slides moving smoothly.
Small Conveyor Drives
Supply a short conveyor section with a few pneumatic stops and guides, where the automatic drain reduces maintenance on a busy line.
Machine Tool Lubrication
Use on a small machine tool's air circuit to filter and regulate the pilot air while misting oil to a downstream lubricator-dependent valve.
Is the Airtac GAFC Air Service Unit GAFC300N10ASK the Right Air-Prep Unit?
Choose the GAFC300N10ASK when you need a 3/8in F.R.L. combination with automatic condensate removal and a nylon bowl. The N before the port means nylon; the A after the port means the automatic drain, so no manual intervention is needed. The 40 um element is the standard grade, and the fitted gauge shows MPa/psi. For a larger flow envelope, step up to the GAFC400 with its 6000 L/min curve at 0.7 MPa inlet; for a smaller footprint, the GAFC200 offers a 1750 L/min envelope. The two units are orderable separately as GAFR300-10 and GAL300-10. Since the lubricator adds oil mist, choose a plain GAFR filter-regulator if the line must stay oil-free. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 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 GAFC300N10ASK FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 oil. The drain bowl holds 60 cc and the oil bowl 98 cc, with a total weight of 1020 g.
The K code indicates the reverse-flow (reflux) valve is fitted. The catalogue shows it as a separate pneumatic symbol. This model also has a nylon bowl (N before the port) and an automatic drain (A after the port).
