About the Airtac GAFC Air Service Unit GAFC300N15SNWK
This GAFC300 F.R.L. combination cleans the air with a 5 um element, sets pressure to 0.15-0.9 MPa (20-130 psi), then adds a metered oil mist from the lubricator. The filter and regulator share one body, so the whole set is two pieces on a T-bracket with quick clamps, not three separate units.
The 1/2in port and 1020 g mass put it in the mid-size class for shop air. Its 60 cc condensate bowl and 98 cc oil bowl set the service rhythm. A nylon bowl is fitted, and the gauge connection is 1/8in since no gauge ships with this model.

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 GAFC300N15SNWK Is Used
Precision Valve Control
The 5 um element filters fine particles that could clog small pilot valves on a CNC machine's tool changer, while the regulator holds a stable setpoint for consistent actuation.
Assembly Line Lubrication
Feed a multi-station assembly fixture with cleaned, regulated air and a controlled oil mist to keep pneumatic slides and grippers moving smoothly on a 1/2in branch line.
Test Bench Air Supply
Provide a clean, pressure-stable air source for a lab test bench where a 5 um filter protects sensitive flow meters and the lubricator maintains cylinder performance.
Is the Airtac GAFC Air Service Unit GAFC300N15SNWK the Right Air-Prep Unit?
The GAFC300 body with a 1/2in port suits branch lines feeding several actuators. The nylon bowl is a build choice; the shared specification of 1.0 MPa max and -5 to 70 C applies, so confirm the material fits your environment. The 5 um element traps finer particles than the standard 40 um, useful for precision valves, but expect more frequent element service. Both semi-auto and manual drains are fitted, so condensate dumps on pressure drop or on demand. The reverse-flow (reflux) valve is included, and the catalogue shows it as a separate pneumatic symbol. For spares, order GAFR300-15 and GAL300-15 separately. 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, so plan supply pressure carefully 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 GAFC300N15SNWK FAQ
This F.R.L. combination operates at 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 is rated for -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 N in the code after the port means no gauge is supplied. If you need to read the set pressure, you can add one to the 1/8in gauge connection on the GAFC300 body. The 5 um element and nylon bowl are the other key options on this build.
