About the Airtac GAFC Air Service Unit GAFC300N08SNK
This AirTAC GAFC300N08SNK is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure setting, then a separate lubricator adds a metered oil mist downstream. With a 1/4in port and a 1020 g mass, it suits small to mid-size machines where a full three-body train would be overkill. The nylon bowl is specified here, and the shared specification of 1.0 MPa max pressure and -5 to 70 C applies regardless of bowl material.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), set with the regulator knob. A 40 um element traps common workshop particles, while the 60 cc condensate bowl and 98 cc oil bowl define the service interval. No gauge is fitted, so the 1/8in gauge connection is available if you add one later. The reverse-flow (reflux) valve is included, 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 GAFC300N08SNK Is Used
Precision Jig Cylinders
Feed a single-acting cylinder on a drilling jig with regulated air at 0.4 MPa. The 40 um element protects the cylinder seals, and the lubricator keeps the rod moving smoothly.
Small Conveyor Stop
Power a pneumatic stop on a light conveyor line. The 1/4in port matches small solenoid valves, and the 60 cc condensate bowl handles moisture from a typical compressor.
Bench Test Rig
Supply a bench-mounted pressure test fixture with clean, regulated air. The nylon bowl resists common workshop oils, and the manual drain lets you purge condensate between test runs.
Is the Airtac GAFC Air Service Unit GAFC300N08SNK the Right Air-Prep Unit?
Choose this GAFC300N08SNK when you need a 1/4in port with a nylon bowl and no gauge. The semi-auto drain dumps condensate when pressure drops, and the manual drain gives you on-demand control. The 40 um element is the standard grade; step up to the 5 um W option for finer filtration if your downstream valves require it. The PT thread comes with a gauge scale in MPa/psi, though this model ships without a gauge. The reverse-flow valve is fitted, so confirm that is what your circuit needs.
For a smaller footprint, the GAFC200 offers a 1/8in port with a 25 cc condensate bowl and a 1750 L/min flow curve at 0.7 MPa inlet. If you need more capacity, the GAFC400 moves up to a 3/8in port with a 100 cc bowl. The two units are orderable separately as GAFR300-08 and GAL300-08. Max supply of 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan your inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N08SNK 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. Use ISO VG 32 lubricant. The complete unit weighs 1020 g.
The N before the port code specifies a nylon bowl, which is a material choice within the same 1.0 MPa and -5 to 70 C specification as PC or metal bowls. The N after the port code means no gauge is supplied; the 1/8in gauge connection is there if you add one. The K at the end indicates the reverse-flow valve is fitted.
