About the Airtac GAFC Air Service Unit GAFC300N08LNWK
This GAFC300N08LNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 1/4in port size and 1020 g mass place it in the mid-range class, suitable for feeding a single machine station or a small pneumatic circuit. The nylon bowl holds 60 cc of condensate, while the separate oil reservoir holds 98 cc, and the 5 um element traps fine particles for sensitive downstream components.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). No gauge is supplied, so the 1/8in gauge connection must be fitted if you need to read the set pressure. The reverse-flow valve is included, and the unit operates from -5 to 70 C, requiring ISO VG 32 lubricant in the oil bowl.

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 GAFC300N08LNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line where 5 um filtration protects tight clearances and the 0.4 MPa cap prevents over-pressurizing delicate actuators.
Small assembly station
Supply a bench-top assembly fixture with a single clamping cylinder, using the 60 cc condensate bowl to handle moisture from a humid compressor line between maintenance rounds.
Instrument air circuit
Protect a lab-scale pneumatic instrument that requires clean, regulated air at moderate pressure, with the 5 um element and lower-pressure range matching its operating envelope.
Is the Airtac GAFC Air Service Unit GAFC300N08LNWK the Right Air-Prep Unit?
Choose this GAFC300N08LNWK when your application needs fine 5 um filtration and a regulated output capped at 0.4 MPa. The nylon bowl is specified by the N code, and the semi-auto drain (which dumps on pressure drop) plus manual drain are both fitted. The reverse-flow valve is present, and the PT thread with MPa/psi gauge scale matches standard regional fittings. For oil-free lines, omit the lubricator and select a plain GAFR300-08 filter-regulator instead; the spares for this unit are GAFR300-08 and GAL300-08.
A 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan your inlet pressure carefully if you need to operate near the ceiling.
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 GAFC300N08LNWK FAQ
This unit operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl 98 cc. Recommended lubricant is ISO VG 32. The complete assembly weighs 1020 g and uses a 1/4in 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 compatible gauge if you need to monitor the output pressure. The PT thread and MPa/psi scale apply to any gauge you add.
