About the Airtac GAFC Air Service Unit GAFC300C10SNK
This AirTAC GAFC300C10SNK is a two-piece F.R.L. combination: the filter and pressure regulator share one body, and a separate lubricator is mounted on the same T-bracket. The 3/8in port size and 1020 g mass place it in the mid-range class, between the lighter GAFC200 and the heavier GAFC400. It operates at 0.15-0.9 MPa (20-130 psi) and filters to 40 um.
The metal bowl is specified by the C code, a build choice for the unit's environment. With a 60 cc condensate bowl and a 98 cc oil bowl, the service interval is set by how much moisture and oil the application consumes. The reverse-flow valve is fitted per the K code. The gauge is not supplied, but the 1/8in gauge connection is ready for one if you need to read the set pressure.

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 GAFC300C10SNK Is Used
Precision machining center
Feed a 3/8in line to a CNC spindle air curtain or a tool changer mechanism. The 40 um filtration protects sensitive valves, and the regulated pressure keeps actuation consistent.
Assembly station air supply
Supply a multi-fixture assembly bench where operators use pneumatic screwdrivers and push cylinders. The 98 cc oil bowl supports continuous lubrication for the tools.
Packaging line tensioner
Run a film tensioning cylinder on a packaging machine. The metal bowl resists accidental impacts in a busy line, and the 60 cc condensate bowl handles typical moisture loads.
Is the Airtac GAFC Air Service Unit GAFC300C10SNK the Right Air-Prep Unit?
Choose the GAFC300 body for a 3/8in port with a 3500 L/min flow curve plotted at 0.7 MPa inlet, a step up from the GAFC200's 1750 L/min envelope. The C code specifies a metal bowl; the shared specification of 1.0 MPa max and -5 to 70 C does not change with material, so confirm the metal suits your surroundings. This model has the semi-auto drain that dumps on pressure drop plus a manual drain for on-demand use, and the 40 um element is the standard grade. The N code means no gauge is fitted; the 1/8in connection allows one to be added. The K code includes the reverse-flow valve, which the catalogue shows as a separate pneumatic symbol. The two units are orderable separately as GAFR300-10 and GAL300-10. 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 a supply near 1.0 MPa if you need the full 0.9 MPa output.
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 GAFC300C10SNK 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 must not freeze. The condensate bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The unit weighs 1020 g.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so you can fit a compatible gauge if you need to read the outlet pressure. The default PT thread uses a gauge scale of MPa/psi.
