About the Airtac GAFC Air Service Unit GAFC300N08SWK
Air enters the GAFC300N08SWK through a 1/4in port and first passes through a 5 um filter element inside the shared filter-regulator body, where solids and moisture are removed and pressure is set to 0.15-0.9 MPa (20-130 psi). The downstream lubricator then adds a controlled oil mist, so the air leaves cleaned, regulated and lubricated for the pneumatic circuit.
This F.R.L. combination is built from two units on one T-bracket: the filter-regulator and the lubricator. The nylon bowl holds 60 cc of condensate while the separate oil bowl holds 98 cc, and the complete assembly weighs 1020 g. The reverse-flow (reflux) valve is fitted, and the circular gauge reads in MPa/psi for the PT thread.

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 GAFC300N08SWK Is Used
Precision valve actuation
The 5 um element protects sensitive solenoid valves on a small assembly station, where fine particles would otherwise cause sticking or premature wear.
Packaging line cylinders
A 1/4in port and 3500 L/min envelope at 0.7 MPa inlet feed short-stroke cylinders on a carton erector, with the lubricator keeping rod seals conditioned.
Machine tool coolant valves
Regulated air at 0.15-0.9 MPa (20-130 psi) operates coolant control valves on a CNC lathe, where the 60 cc condensate bowl handles moisture from humid shop air.
Is the Airtac GAFC Air Service Unit GAFC300N08SWK the Right Air-Prep Unit?
The GAFC300 body with a 1/4in port suits medium-duty circuits; the 60 cc drain bowl and 98 cc oil bowl define the service interval, and the 5 um element traps finer particles than the standard 40 um grade, which means more frequent element checks. The semi-auto drain dumps condensate when pressure drops, with a manual drain for on-demand use, and the nylon bowl is a build choice - the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of material, so confirm nylon suits your environment. The fitted gauge reads MPa/psi on the PT thread, and the reverse-flow valve is present as an ordering option. Spare parts are orderable as GAFR300-08 and GAL300-08. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan 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 GAFC300N08SWK FAQ
This F.R.L. combination 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 the recommended lubricant is ISO VG 32. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g with a 1/4in port.
The 5 um element is specified for finer filtration, catching particles that a 40 um grade would pass, which suits precision pneumatic components. The reverse-flow (reflux) valve is fitted as an ordering option, shown as a separate symbol in the catalogue - it is present on this unit but its detailed function is covered separately.
