About the Airtac GAFC Air Service Unit GAFC300N08LWK
This GAFC300N08LWK 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 and 1020 g mass place it in the mid-size class, suited for a single machine station or a small production cell. Air enters the first body where the 5 um element removes fine particles and the regulator sets pressure to 0.15-0.4 MPa (20-58 psi), then the lubricator adds a metered oil mist downstream.
The nylon bowl holds 60 cc of condensate while the oil bowl carries 98 cc, so the service interval is driven by how often the line is wet rather than by the element alone. The circular gauge is fitted with an MPa/psi scale for the PT thread. A reverse-flow (reflux) valve is included, shown as a separate symbol in the catalogue. Max supply is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi), with a -5 to 70 C operating range.

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 GAFC300N08LWK Is Used
Precision valve actuation
Feed a bank of small pneumatic valves on an assembly fixture where regulated 0.15-0.4 MPa air and 5 um filtration protect tight-clearance spools from wear.
Laboratory air supply
Supply a lab bench with cleaned, regulated air for a small test rig or a single analytical instrument that needs fine particle removal and a lower pressure ceiling.
Maintenance workshop bench
Run a workshop bench with a small air tool or a blow-off station where the lower pressure range prevents over-pressurizing delicate components being cleaned or tested.
Is the Airtac GAFC Air Service Unit GAFC300N08LWK the Right Air-Prep Unit?
Choose the GAFC300N08LWK when your line needs lower regulated pressure and fine filtration. The L type tops out at 0.4 MPa (20-58 psi), so if the machine may ever require more than that, step to a standard S type instead. The 5 um element traps finer particles than the standard 40 um grade, which suits precision valves or instrument air, but expect more frequent element service. The nylon bowl is a build choice; the shared specification of 1.0 MPa max and -5 to 70 C applies regardless, so confirm the material fits your surroundings. The semi-auto drain dumps condensate on each pressure drop while the manual drain gives on-demand control. The gauge reads in MPa/psi for the PT thread. If the line must stay oil-free, omit the lubricator and choose a plain GAFR300-08 filter-regulator instead. Spare parts are orderable as GAFR300-08 and GAL300-08. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this unit's 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.

This F.R.L. combination 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). The temperature range is -5 to 70 C and the recommended lubricant is ISO VG 32. It has a 60 cc drain bowl and a 98 cc oil bowl, weighs 1020 g, and uses a 5 um element. The gauge is fitted with an MPa/psi scale for the PT thread.
The K indicates a reverse-flow (reflux) valve is fitted to this unit. The catalogue shows it as a separate pneumatic symbol. It is an ordering difference from models without the K, and its detailed function is covered on a separate page in the catalogue.
