About the Airtac GAFC Air Service Unit GAFC300C15SNWK
This AirTAC GAFC300C15SNWK is a two-piece F.R.L. combination. The first body houses both the filter and the regulator, so air is cleaned and set to pressure before it moves on. The second body is the lubricator, which adds a metered oil mist downstream. With a 1/2in port and a 1020 g mass, it suits medium-size machine headers where a single point of air preparation is needed.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 5 um element for finer filtration. The metal bowl is specified by the C code. No gauge is supplied on this model, so the gauge connection (1/8in) is where one would be added. The reverse-flow (reflux) valve is fitted, and the catalogue shows it as a separate pneumatic symbol.

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 GAFC300C15SNWK Is Used
Precision valve control
Feed a bank of pneumatic valves on a small assembly station. The 5 um element protects fine internal passages from particle wear, while the regulator holds the set pressure for consistent actuator force.
Machine tool lubrication
Supply a single-axis drilling or tapping unit with filtered, regulated air and a controlled oil mist. The 60 cc condensate bowl and 98 cc oil bowl support a full shift between checks.
Packaging line retrofit
Upgrade a carton-erecting machine's air prep. The 1/2in port and 1020 g weight fit existing headers, and the metal bowl suits a plant floor where accidental impacts are possible.
Is the Airtac GAFC Air Service Unit GAFC300C15SNWK the Right Air-Prep Unit?
Choose the GAFC300 body for flows up to the plotted 3500 L/min envelope at 0.7 MPa inlet, a step up from the GAFC200's 1750 L/min curve. The 1/2in port (code 15) is the largest offered on this body. The metal bowl is a build choice; the shared specification of 1.0 MPa max and -5 to 70 C applies regardless, so confirm it suits your environment. The semi-auto drain dumps condensate on pressure drop, with a manual backup. The 5 um element traps finer particles than the standard 40 um, at the cost of more frequent service. The PT thread carries a MPa/psi gauge scale, but no gauge is fitted here. The K code adds the reverse-flow valve. Spares are the GAFR300-15 filter & regulator and the GAL300-15 lubricator. With a 1.0 MPa max supply, there is about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan inlet pressure near maximum if you need the full output.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAFR300-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300C15SNWK FAQ
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C. It has a 60 cc drain bowl and a 98 cc oil bowl, weighs 1020 g, and uses ISO VG 32 lubricant. The 5 um element and metal bowl are fitted.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so a circular gauge with an MPa/psi scale (matching the PT thread) can be added there. Without one, the set pressure cannot be read directly on the unit.
