About the Airtac GAFC Air Service Unit GAFC300N08S
This AirTAC GAFC300N08S is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. Air enters the first body where the 40 um element removes moisture and solids, and the regulator sets pressure to 0.15-0.9 MPa (20-130 psi); the lubricator then adds a metered oil mist downstream, so oil never travels back through the regulator seat.
The 1/4in port suits small to mid-size actuators, and the nylon bowl keeps the unit light at 1020 g while holding 60 cc of condensate and 98 cc of oil. The circular gauge is fitted with an MPa/psi scale for the default PT thread. Rated for -5 to 70 C, it must not freeze, so keep it out of unheated winter lines.

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 GAFC300N08S Is Used
Small Assembly Jigs
Feed a pneumatic press or clamping jig on a workbench where 1/4in piping and a 1020 g unit keep the setup compact, with the 98 cc oil bowl reducing refill stops.
Single-Actuator Conveyor
Power a short conveyor's tensioning cylinder with regulated air at 0.15-0.9 MPa, while the 60 cc condensate bowl handles moisture from a humid shop line.
Lab Pneumatic Circuits
Supply a test bench with filtered, regulated air and controlled lubrication for a single valve manifold, where the nylon bowl's lighter weight eases panel mounting.
Is the Airtac GAFC Air Service Unit GAFC300N08S the Right Air-Prep Unit?
Choose the GAFC300N08S when a 1/4in port matches your air prep point and you want the nylon bowl option, which is a build choice for lighter weight. The semi-auto drain dumps condensate each time pressure drops, while the manual drain gives on-demand control; the 60 cc bowl sets the service rhythm. The standard type regulates 0.15-0.9 MPa (20-130 psi), and the 40 um element handles general shop air; step to the 5 um element if you feed precision valves. The PT thread carries an MPa/psi gauge scale, so operators read the setpoint directly. Replacement units are orderable as GAFR300-08 and GAL300-08, keeping spares simple. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan supply pressure accordingly if you need the full output.
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 GAFC300N08S FAQ
The GAFC300N08S operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. It has a 60 cc condensate bowl and a 98 cc oil bowl, weighs 1020 g, and uses ISO VG 32 lubricant. The 40 um element handles standard shop air.
The N code specifies a nylon bowl, which is a material choice for the 60 cc condensate and 98 cc oil chambers. The catalogue lists the same 1.0 MPa max pressure and -5 to 70 C range for PC, metal, and nylon bowls, so confirm nylon suits your specific environment. The semi-auto and manual drains are both fitted on this model.
