About the Airtac GAFC Air Service Unit GAFC300N08L
The GAFC300N08L is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared bracket with quick clamps. Air is cleaned and set to pressure in the first body, then the lubricator meters oil mist into the flow last, so oil never travels back through the regulator seat. This unit uses a 1/4in port and weighs 1020 g, placing it in the mid-range size class for shop air systems.
It regulates from 0.15 to 0.4 MPa (20-58 psi), which suits low-pressure circuits that never need more than 58 psi. The 40 um filter element handles standard shop air, while the 60 cc condensate bowl and 98 cc oil bowl define the service interval. The nylon bowl is a build choice; the shared specification of 1.0 MPa max and -5 to 70 C applies regardless, so confirm it fits your environment. A circular gauge is fitted, reading in MPa and psi.

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 GAFC300N08L Is Used
Low-Pressure Assembly Fixtures
Feed a bench-mounted press or clamping fixture that operates below 58 psi, where the lower-pressure range prevents over-forcing delicate parts.
Light Conveyor Controls
Supply air to a small conveyor's guide rails and stop gates, with the 1/4in port matching typical valve manifolds on compact lines.
Test Bench Air Supply
Provide regulated air to a lab test jig that requires a stable low pressure, with the 60 cc bowl handling condensate from a modest duty cycle.
Is the Airtac GAFC Air Service Unit GAFC300N08L the Right Air-Prep Unit?
Choose the GAFC300N08L when your circuit runs below 0.4 MPa and you want the two-piece layout that saves one inter-unit joint compared to a three-body train. The 1/4in port suits small to mid-size actuators; if you need more flow, step up to a GAFC400 with its 6000 L/min envelope at 0.7 MPa inlet, or down to a GAFC200 for lighter duty. The nylon bowl is specified by the N before the port code, and the semi-auto drain dumps condensate on pressure drop while the manual drain gives on-demand control. The 40 um element is standard; select the W option for 5 um filtration if you feed precision valves. The PT thread carries a gauge scaled in MPa/psi, and no reverse-flow valve is fitted. For spares, order GAFR300-08 and GAL300-08 separately. If the line must stay oil-free, omit the lubricator and choose a plain GAFR filter-regulator instead. 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, so plan the inlet pressure accordingly.
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 GAFC300N08L FAQ
The GAFC300N08L operates from 0.15 to 0.4 MPa (20-58 psi), with a maximum 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 it uses ISO VG 32 lubricant. It has a 60 cc drain bowl and a 98 cc oil bowl, and the complete unit weighs 1020 g.
The N before the port code specifies a nylon bowl. The catalogue lists PC, metal, and nylon as options, and the pressure and temperature ratings are identical for all three. The choice is a build preference, so confirm the nylon suits your specific operating environment before installation.
