About the Airtac GAFC Air Service Unit GAFC300N08ASWK
The GAFC300N08ASWK is an F.R.L. combination built as two joined units: a filter-regulator body followed by a lubricator on a shared bracket. Air enters through a 1/4in port, passes the 5 um filter element, gets regulated to 0.15-0.9 MPa (20-130 psi), then receives a metered oil mist from the lubricator before exiting. The nylon bowl holds 60 cc of condensate while the oil bowl holds 98 cc, and the whole assembly weighs 1020 g.
With the automatic drain, condensate clears itself without an operator, and the circular gauge (reading MPa/psi) shows the set pressure at a glance. The reverse-flow valve is fitted per the K code. The catalogue flow curve for this body is plotted to 3500 L/min at 0.7 MPa inlet, so it suits medium-duty lines feeding several actuators from one header.

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 GAFC300N08ASWK Is Used
CNC spindle lubrication
Feed a 5 um-filtered, regulated air supply to a CNC spindle air curtain while the lubricator adds ISO VG 32 oil for the tool changer mechanism. The 1/4in port matches typical machine-tool sub-circuits.
Assembly station air prep
Power a multi-fixture assembly bench where three or four pneumatic screwdrivers share one supply. The 98 cc oil bowl keeps lubricant available across a full shift, and the auto drain handles condensate from humid plant air.
Packaging line actuators
Run a carton-erecting station with several small cylinders and a vacuum generator. The 5 um element protects precision pilot valves, while the nylon bowl suits areas where metal bowls are overkill and PC might be a concern.
Is the Airtac GAFC Air Service Unit GAFC300N08ASWK the Right Air-Prep Unit?
Choose the GAFC300 body when you need 1/4in ports and a 1020 g unit that fits between smaller GAFC200 and larger GAFC400 machines. The nylon bowl is a material choice, not a performance upgrade - the 1.0 MPa maximum and -5 to 70 C range stay the same across bowl materials, so confirm nylon suits your environment. The automatic drain (A) removes condensate continuously, which helps on wet supply lines where manual draining gets skipped. The 5 um element traps finer particles than the standard 40 um, but it will need more frequent service. The PT thread carries a MPa/psi gauge scale, and the reverse-flow valve is fitted. Spares are orderable as GAFR300-08 and GAL300-08.
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 your inlet pressure carefully 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 GAFC300N08ASWK FAQ
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1020 g and the flow curve is plotted to 3500 L/min at 0.7 MPa inlet.
The K indicates a reverse-flow (reflux) valve is fitted to the GAFC300N08ASWK. The catalogue shows this as a separate pneumatic symbol on the unit's schematic. It is an ordering difference from models without the K code, and the valve's detailed operation is covered on its own catalogue page.
