Airtac GAFC Air Service Unit GAFC300N10ASNWK
The AirTAC Airtac GAFC Air Service Unit GAFC300N10ASNWK 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 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC300N10ASNWK
This GAFC300 F.R.L. combination cleans the air, sets its pressure, then adds a controlled oil mist in a single two-piece build. A 3/8in port and 1020 g mass place it in the mid-range class, sized for a machine station or a small assembly line rather than a single jig.
The first body houses both the 5 um filter element and the regulator, so the air is cleaned and set to 0.15-0.9 MPa (20-130 psi) before the lubricator adds oil last. The nylon bowl holds 60 cc of condensate, while the separate oil bowl holds 98 cc. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/8in gauge connection.

| A | Drain: Automatic drain. |
| S | Standard type — 0.15 - 0.9 MPa (20 - 130 psi). This body offers Standard (S) or Lower pressure (L). |

Constituent units, orderable separately as spares: GAFR300-10 filter & regulator, GAL300-10 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.

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 GAFC300N10ASNWK Is Used
CNC coolant valves
Feed a 5 um-filtered, regulated supply to solenoid valves controlling coolant flow on a CNC lathe, where fine particles would otherwise wear valve seats.
Assembly station air
Supply a pneumatically driven screwdriver on a bench assembly station, with the lubricator adding oil mist to keep the tool motor running smoothly.
Packaging line sensors
Power a series of air cylinders on a carton-erecting machine, where the automatic drain handles condensate from a non-stop production schedule.
Is the Airtac GAFC Air Service Unit GAFC300N10ASNWK the Right Air-Prep Unit?
Choose this model when you need fine 5 um filtration and automatic condensate removal in a 3/8in line. The nylon bowl is a build choice, not a performance upgrade - the 1.0 MPa (145 psi) maximum and -5 to 70 C range apply to all bowl materials, so confirm nylon suits your environment. The automatic drain clears water without an operator, which suits unattended or wet supply lines.
The reverse-flow (reflux) valve is fitted, shown as a separate symbol in the catalogue. The two units are orderable separately as GAFR300-10 and GAL300-10, so a damaged bowl does not mean replacing the whole assembly. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 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 GAFC300N10ASNWK FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Operating temperature is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl 98 cc. Use ISO VG 32 lubricant. The complete unit weighs 1020 g.
The N after the port code means no gauge is supplied. The 1/8in gauge connection is still there, so you can add a circular gauge later if operators need to read the set pressure directly. Until then, the regulated pressure cannot be verified without a separate test gauge.
