About the Airtac GAFC Air Service Unit GAFC300N08LK
This AirTAC GAFC300N08LK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket with quick clamps. Air enters the 1/4in port, gets filtered and regulated to a lower pressure band of 0.15-0.4 MPa (20-58 psi), then oil mist is metered in downstream. The nylon bowl holds 60 cc of condensate, while the separate oil bowl holds 98 cc, and the whole unit weighs 1020 g.
The filter element is 40 um, and a circular gauge with an MPa/psi scale is fitted. A reverse-flow (reflux) valve is included, shown as a separate symbol in the catalogue. The semi-auto drain releases condensate when pressure drops, and a manual drain is also fitted for on-demand use. Rated for -5 to 70 C, it must not freeze, and the recommended lubricant is ISO VG 32.

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 GAFC300N08LK Is Used
Precision Pressure Control
Feed a precision air bearing or a delicate gripper on a small assembly station, where the lower 0.4 MPa ceiling prevents over-force and the 40 um element keeps the air clean.
Single-Actuator Test Rig
Power a single 1/4in pneumatic cylinder on a benchtop test rig, using the 60 cc condensate bowl to catch moisture from a humid compressor line and the manual drain for quick purging.
Light-Duty Conveyor Section
Lubricate the air for a small conveyor section's stop gates, where the 98 cc oil bowl keeps a metered mist flowing to the valves and the semi-auto drain clears water on each pressure drop.
Is the Airtac GAFC Air Service Unit GAFC300N08LK the Right Air-Prep Unit?
Choose the GAFC300N08LK when your circuit needs a 1/4in port and a regulated output capped at 0.4 MPa (20-58 psi). The lower-pressure type suits delicate actuators or air bearings where a standard 0.9 MPa setting would be excessive. The nylon bowl is a material choice, not a performance upgrade; the shared specification of 1.0 MPa max and -5 to 70 C applies, so confirm it suits your environment. The 40 um element handles general workshop air, and the fitted gauge reads in MPa/psi for the PT thread. The semi-auto and manual drains give you both automatic dumping on pressure loss and manual control. The reverse-flow valve is fitted per the K code. Spares are the GAFR300-08 filter-regulator and the GAL300-08 lubricator, both orderable separately. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range.
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 GAFC300N08LK FAQ
The GAFC300N08LK is a lower-pressure F.R.L. combination with a working range of 0.15-0.4 MPa (20-58 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1020 g.
The K code specifies a reverse-flow (reflux) valve, which is fitted as a separate pneumatic symbol in the catalogue; its detailed function is covered on its own page. The L code sets the regulated output to 0.15-0.4 MPa (20-58 psi) instead of the standard 0.15-0.9 MPa, making it suitable for circuits that must not exceed 0.4 MPa. The nylon bowl is a material choice, and the gauge reads in MPa/psi for the PT thread.
