About the Airtac GAFC Air Service Unit GAFC300C10ASNK
This AirTAC GAFC300C10ASNK is an F.R.L. combination built as two units on one T-shape bracket: a filter-regulator body and a separate lubricator. The 3/8" port size and 1020 g mass put it in the mid-range class, suitable for feeding a small machine station or a bank of actuators.
The filter-regulator stage cleans the air and sets pressure to 0.15-0.9 MPa (20-130 psi), then the lubricator adds a metered oil mist downstream. The 60 cc condensate bowl and 98 cc oil bowl define the service interval. No gauge is fitted, so the 1/8" gauge connection is available if you add one later. A reverse-flow valve is included, and the automatic drain clears condensate without operator attention.

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 GAFC300C10ASNK Is Used
Precision Valve Control
Feed a bank of precision pneumatic valves on a small assembly station, where the 40 um element and regulated 0.15-0.9 MPa output keep actuation consistent.
Machine Tool Lubrication
Supply a single CNC machine's air cylinder circuit with filtered, regulated air and a controlled oil mist for the tool changer mechanism.
Packaging Line Actuators
Run a carton erector's pneumatic cylinders on a packaging line, where the automatic drain reduces maintenance on a continuously operating system.
Is the Airtac GAFC Air Service Unit GAFC300C10ASNK the Right Air-Prep Unit?
Choose the GAFC300C10ASNK when you need a 3/8" port with a metal bowl and automatic drain. The metal bowl is a build choice for the condensate side, though the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of material - confirm it suits your environment. The automatic drain suits unattended lines, while the standard pressure type covers 0.15-0.9 MPa (20-130 psi) for most shop air. The 40 um element handles general pneumatic duty; step to the 5 um element if you need finer filtration for precision valves. The reverse-flow valve is fitted per the K code, and the PT thread with MPa/psi gauge scale matches standard local fittings. Spare parts are orderable as GAFR300-10 and GAL300-10. 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 the supply pressure accordingly.
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 GAFC300C10ASNK FAQ
The GAFC300C10ASNK 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). Temperature range is -5 to 70 C. It has a 60 cc condensate bowl and a 98 cc oil bowl, weighs 1020 g, and uses ISO VG 32 lubricant.
The N after the port code means no gauge is supplied. The gauge connection on the GAFC300 body is 1/8", so you can add a circular gauge later if you need to read the set pressure directly. Without one, you cannot verify the regulated output visually.
