About the Airtac GAFC Air Service Unit GAFC300N10SNK
This AirTAC GAFC300N10SNK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted together on a T-bracket with quick clamps. The 3/8in port size and 1020 g weight place it in the mid-range GAFC300 class, suitable for feeding a single machine station or a small bank of actuators. The nylon bowl is specified by the N code, and the 40 um element handles standard shop air.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a max supply of 1.0 MPa (145 psi). Air is filtered and regulated in the first body, then the lubricator adds a metered oil mist downstream, so oil never passes back through the regulator seat. The 60 cc condensate bowl and 98 cc oil bowl define the service interval, and the unit must not freeze, with a rated range of -5 to 70 C.

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 GAFC300N10SNK Is Used
Precision Fixture Clamping
Feed a single-station pneumatic fixture on a CNC machining center. The 3/8in port and 1020 g weight suit a compact mounting plate, while the 40 um element protects the clamp valves from pipe scale.
Small Conveyor Drive
Power a short belt conveyor with a single air motor or a pair of cylinders. The 60 cc condensate bowl handles typical moisture from a small compressor, and the semi-auto drain clears it on each shutdown.
Bench Assembly Station
Supply a manual assembly bench with a pneumatic screwdriver or a small press. The lubricator adds ISO VG 32 oil mist to the tool, and the 98 cc oil bowl keeps the lubricator topped up across a shift.
Is the Airtac GAFC Air Service Unit GAFC300N10SNK the Right Air-Prep Unit?
The GAFC300N10SNK uses a 3/8in port (code 10), sitting between the smaller GAFC200 (1/8in-1/4in, 590 g) and the larger GAFC400 (3/8in-1/2in, 1810 g) in the range. The nylon bowl is a build choice, not a performance upgrade, and the shared specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm it suits your environment. The drain is the standard semi-auto plus manual type: the semi-auto dumps condensate each time pressure drops, while the manual drain gives on-demand control. No gauge is fitted, so the 1/8in gauge connection is available if you add one later. The reverse-flow (reflux) valve is fitted, shown as a separate symbol in the catalogue. The 40 um element is the standard grade; the 5 um W option is available for finer filtration. Thread is PT with an MPa/psi gauge scale. Spare parts are orderable as GAFR300-10 and GAL300-10. The 1.0 MPa max supply leaves about 0.1 MPa 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 GAFC300N10SNK FAQ
The GAFC300N10SNK 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). The temperature range is -5 to 70 C and it must not freeze. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The unit weighs 1020 g and has a 3/8in port.
The N after the port code means no gauge is supplied. The gauge connection on the GAFC300 body is 1/8in, so you can fit a standard AirTAC gauge there if you need to read the set pressure. Without a gauge, the outlet pressure cannot be verified visually, so plan for a separate gauge or a test point.
