About the Airtac GAFC Air Service Unit GAFC300N08LW
This AirTAC GAFC300N08LW 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, it handles 0.15-0.4 MPa (20-58 psi) and uses a 5 um element to catch fine particles before air reaches the lubricator.
The nylon bowl holds 60 cc of condensate and the oil bowl 98 cc, giving a 1020 g unit that suits panel mounting. The circular gauge reads in MPa and psi, while the semi-auto drain dumps condensate on pressure drops and the manual drain works on demand. Oil mist is added last, downstream of the regulator seat.

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 GAFC300N08LW Is Used
Precision machining spindles
Feed a 5 um-filtered, lower-pressure air supply to a CNC spindle air curtain or bearing pressurization line, where fine particle control matters and regulated pressure stays below 0.4 MPa.
Laboratory air benches
Supply instrument air to a lab bench pneumatic actuator or valve manifold, using the 5 um element to protect sensitive components and the lower pressure range for delicate operations.
Assembly line pick-and-place
Run a small pick-and-place gripper or a single-axis slide on a 1/4in line, where the 60 cc condensate bowl and 98 cc oil bowl reduce service frequency on a compact machine station.
Is the Airtac GAFC Air Service Unit GAFC300N08LW the Right Air-Prep Unit?
Choose the GAFC300N08LW when your line needs lower regulated pressure up to 0.4 MPa and finer 5 um filtration. The nylon bowl is a build choice; the common specification of 1.0 MPa max and -5 to 70 C applies regardless, so confirm nylon suits your environment. The semi-auto plus manual drain pair covers both automatic dumping and operator-controlled draining.
For a standard 0.15-0.9 MPa range, step to the GAFC30008AS; for a 3/8in port, pick the GAFC30010LW. The GAFR300-08 filter-regulator and GAL300-08 lubricator are orderable separately. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the regulated band.
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 GAFC300N08LW FAQ
The GAFC300N08LW 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. It has a 60 cc drain bowl and 98 cc oil bowl, weighs 1020 g, and uses ISO VG 32 lubricant. The 5 um element filters air before the lubricator adds oil mist.
The L in the code specifies a lower regulated band of 0.15-0.4 MPa, suited for applications that never need more than 0.4 MPa. The W specifies a 5 um element, which traps finer particles than the standard 40 um for precision equipment. The trade-off is that the 5 um element needs more frequent service, and the lower range caps your maximum regulated pressure.
