About the Airtac GAFC Air Service Unit GAFC300N08ALNWK
This GAFC300 F.R.L. combination pairs a filter-regulator with a lubricator on a single T-shape bracket, so the air is cleaned and set to pressure in the first body before oil mist is metered in downstream. The 1/4in port and 1020 g weight place it in the mid-size class, suited to a single machine station or a small assembly bench.
The lower-pressure regulator tops out at 0.4 MPa (20-58 psi), which suits delicate grippers or low-force clamping. The 5 um element traps fine particles for sensitive valves, while the 60 cc condensate bowl and 98 cc oil bowl define the service rhythm. A nylon bowl is fitted, and the unit carries a reverse-flow valve.

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 GAFC300N08ALNWK Is Used
Low-force assembly
Set a delicate press or a small parts feeder to 0.3 MPa without risking over-force, while the 5 um element keeps fine particles away from precision slides.
Laboratory air
Feed a small test rig or a sample preparation station with filtered, regulated air, and let the automatic drain handle condensate during long unattended runs.
Maintenance bench
Power a blow-off nozzle or a small air tool on a service cart, with the lower pressure range protecting sensitive components from accidental over-pressure.
Is the Airtac GAFC Air Service Unit GAFC300N08ALNWK the Right Air-Prep Unit?
Choose the GAFC300N08ALNWK when your line needs fine filtration and a gentle pressure ceiling. The 5 um element protects precision equipment but will need more frequent service than a 40 um unit. The automatic drain clears condensate by itself, and the nylon bowl is a build choice - confirm it suits your environment, as the -5 to 70 C specification applies to all bowl materials. No gauge is supplied, so the 1/8in gauge connection is where you would add one to read the set pressure. The reverse-flow valve is fitted per the K code. Spares are the GAFR300-08 filter-regulator and 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 GAFC300N08ALNWK FAQ
This F.R.L. combination works with air only. The lower-pressure regulator operates from 0.15 to 0.4 MPa (20-58 psi), with a maximum supply of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It runs from -5 to 70 C and must not freeze. The condensate bowl holds 60 cc and the oil bowl 98 cc. Use ISO VG 32 lubricant. The complete unit weighs 1020 g.
The N after the port code means no gauge is supplied with this unit. The GAFC300 body has a 1/8in gauge connection, so you can add a circular gauge there later if you need to read the set pressure directly. Until then, the regulated output is set by the adjusting knob.
