About the Airtac GAFC Air Service Unit GAFC300N10LNWK
This GAFC300 F.R.L. combination pairs a filter-regulator with a lubricator on one T-bracket, so the air is cleaned, set to pressure, then oil-misted in the last stage. The 3/8in port and 1020 g mass suit it for a single machine station or a small assembly bench where the line must stay compact.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 5 um element trapping fine particles before the lubricator adds its metered oil mist. A 60 cc condensate bowl and a 98 cc oil bowl set the service rhythm, and the nylon bowl material is a build choice - the catalogue gives no impact or chemical data, so confirm it suits your surroundings. No gauge is supplied; the 1/8in gauge connection is there if you add one.

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 GAFC300N10LNWK Is Used
Precision valve bench
Feed a bank of small solenoid valves on a test bench where the 5 um element protects fine orifices and the lower pressure range keeps actuation gentle.
Assembly workstations
Supply a pneumatic screwdriver or a small press at a single assembly station, where the compact two-piece build saves rail space and the 98 cc oil bowl lasts a shift.
Lab air circuits
Run a small lab fixture or a pick-and-place gripper that needs clean, regulated air at low pressure, with the nylon bowl offering a lightweight option for benchtop mounting.
Is the Airtac GAFC Air Service Unit GAFC300N10LNWK the Right Air-Prep Unit?
The GAFC300 body with a 3/8in port sits between the smaller GAFC200 (1/4in, 590 g) and the larger GAFC400 (1/2in, 1810 g). The 5 um element filters finer than the standard 40 um, which helps precision valves but means more frequent element service. The semi-auto drain dumps condensate on each pressure drop, with a manual drain for on-demand use. The reverse-flow (reflux) valve is fitted, and the PT thread carries a gauge scale in MPa/psi - though this model ships without a gauge, so the set pressure cannot be read until you add one. The lubricator needs ISO VG 32 oil, and if the line must stay oil-free, choose a plain GAFR300-10 filter-regulator instead. Spares are the GAFR300-10 and GAL300-10, both orderable separately. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the regulated range, so plan the inlet pressure carefully if you need the full band.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFR300-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N10LNWK FAQ
This lower-pressure F.R.L. combination works from 0.15 to 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). 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 unit weighs 1020 g and has a 3/8in port.
The N after the port code means no gauge is supplied - the 1/8in gauge connection is there if you want to add one later. The K code means a reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol. The nylon bowl is a build choice, but the catalogue gives no impact or chemical data, so confirm it fits your environment.
