About the Airtac GAFC Air Service Unit GAFC300N08SNW
This AirTAC GAFC300N08SNW is a two-piece F.R.L. combination: the filter and pressure regulator share one body, and the lubricator mounts on the same T-bracket downstream. With a 1/4in port and a 1020 g mass, it suits medium-size machines where a compact footprint matters more than raw flow capacity.
The 5 um element traps fine particles for sensitive valves, while the nylon bowl holds 60 cc of condensate and the oil bowl 98 cc. It regulates from 0.15 to 0.9 MPa (20-130 psi), and since no gauge is fitted, the 1/8in gauge connection is ready for an add-on 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 GAFC300N08SNW Is Used
Precision valve control
The 5 um element protects pilot valves and precision regulators in a small assembly station from fine abrasive dust that would otherwise wear internal seals.
Single actuator feed
Feed one pneumatic cylinder on a short conveyor section with filtered, regulated, lubricated air at 1/4in port size, keeping the actuator moving smoothly without moisture carryover.
Bench test rig
Supply a lab test fixture with clean, pressure-controlled air at up to 0.9 MPa, while the 5 um element keeps the test piece free of particles that could skew measurements.
Is the Airtac GAFC Air Service Unit GAFC300N08SNW the Right Air-Prep Unit?
Choose the GAFC300N08SNW when you need 1/4in ports with a 5 um element for finer filtration than the standard 40 um. The nylon bowl is a material choice - the catalogue gives no impact or chemical data, so confirm it suits your environment. This model has both semi-auto and manual drains: the semi-auto dumps condensate each time pressure drops, and the manual drain works on demand. The PT thread carries a MPa/psi gauge scale if you add a gauge later.
The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan your inlet pressure carefully if you need the full output.
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 GAFC300N08SNW FAQ
The GAFC300N08SNW operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures. The drain bowl holds 60 cc and the oil bowl 98 cc. Use ISO VG 32 lubricant. The complete unit weighs 1020 g.
The N after the port code means no gauge is supplied with this unit. The GAFC300 body has a 1/8in gauge connection, so you can add a pressure gauge later if you need to read the set pressure. The PT thread option uses a MPa/psi scale on any gauge you fit.
