About the Airtac GAFC Air Service Unit GAFC300N08SNWK
This AirTAC GAFC300N08SNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. With a 1/4in port and a 1020 g mass, it suits panel or frame mounting rather than tubing support alone. The 5 um element traps fine particles for sensitive valves, while the nylon bowl and semi-auto plus manual drain define the service routine.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum supply. Air is filtered and regulated in the first body, then the lubricator adds a metered oil mist downstream, so oil never travels back through the regulator seat. The 60 cc condensate bowl and 98 cc oil bowl set the attendance interval, and the reverse-flow valve is fitted per the K code.

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 GAFC300N08SNWK Is Used
Precision Valve Control
Feed a 5 um-filtered, regulated air supply to a bank of pneumatic pilot valves on a small assembly machine, where fine particles could otherwise jam spool seals.
Light Conveyor Drive
Power a single 1/4in-operated conveyor stop gate or a small index table cylinder, with the lubricator maintaining a consistent oil mist for the actuator seals.
Bench Test Rig
Supply a laboratory test fixture that needs clean, pressure-set air at up to 0.9 MPa, with the 5 um element protecting sensitive flow meters and regulators downstream.
Is the Airtac GAFC Air Service Unit GAFC300N08SNWK the Right Air-Prep Unit?
Choose the GAFC300 body for 1/4in or 3/8in ports; this 08 code is the 1/4in size, sitting between the smaller GAFC200 and the larger GAFC400 in the range. The nylon bowl is specified by the N before the port, and the 5 um element by the W after it - a finer grade than the standard 40 um, so expect more frequent element service. No gauge is supplied (N after the port); the 1/8in gauge connection allows adding one later. The semi-auto drain dumps on pressure drop, with a manual backup for on-demand use, and the PT thread carries an MPa/psi gauge scale if fitted. The reverse-flow valve is present but its function is detailed on the catalogue's separate page. Spares are the GAFR300-08 filter-regulator and GAL300-08 lubricator. 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 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 GAFC300N08SNWK FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 60 cc and the oil bowl 98 cc, with a total weight of 1020 g.
The N after the port code specifies no gauge is supplied, so you cannot read the set pressure without adding one to the 1/8in gauge connection. The K code indicates the reverse-flow (reflux) valve is fitted; the catalogue shows this as a separate pneumatic symbol with its own reference page.
