About the Airtac GAFC Air Service Unit GAFC300N08SW
This AirTAC GAFC300N08SW 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 1/4in port, gets filtered and regulated to 0.15-0.9 MPa (20-130 psi), then the lubricator adds a metered oil mist as the final step. The 5 um element traps finer particles than the standard 40 um grade, which suits precision valves but means more frequent element checks.
The nylon bowl is a build choice, not a performance upgrade - the common specification (1.0 MPa max, -5 to 70 C) stays the same across materials, so confirm it fits your environment. The 60 cc condensate bowl and 98 cc oil bowl set the service rhythm; with a 1020 g mass, this unit needs a proper panel mount rather than tubing support. A circular gauge is fitted, reading MPa/psi for the default PT thread.

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 GAFC300N08SW Is Used
CNC Tool Changer
Feed a 1/4in line to a CNC tool changer cylinder, where the 5 um element protects the precision spool valve from fine wear particles and the lubricator keeps the sliding mechanism moving.
Packaging Machine Guide Rail
Supply a packaging machine's guide rail positioning cylinders with filtered, regulated air at 0.15-0.9 MPa (20-130 psi), with the oil mist reducing seal friction on frequent cycles.
Assembly Bench Air Tools
Run a small assembly bench's pneumatic screwdrivers from this unit, where the 60 cc condensate bowl handles a shift's moisture and the 5 um element keeps tool internals clean.
Is the Airtac GAFC Air Service Unit GAFC300N08SW the Right Air-Prep Unit?
Choose the GAFC300 for 1/4in to 1/2in lines where the 3500 L/min flow envelope (plotted at 0.7 MPa inlet) covers a single machine station. The nylon bowl is lighter than metal but the catalogue gives no impact or chemical data, so verify it suits your shop atmosphere. The semi-auto drain dumps condensate on each pressure drop while the manual drain gives on-demand control - both are fitted here. The 5 um element is the finer filtering option, ideal for instrument air but requiring more frequent service than the 40 um standard. The PT thread carries an MPa/psi gauge scale, matching most export markets. If the line must stay oil-free, omit the lubricator and choose a plain GAFR300-08 filter-regulator instead. Spare parts are orderable separately 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 the 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 GAFC300N08SW FAQ
The GAFC300N08SW 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). It works in -5 to 70 C temperatures and needs ISO VG 32 lubricant. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g. The 5 um element filters the air before the lubricator adds oil mist.
The N in the code specifies a nylon bowl, which is one of three material options (PC, metal, nylon) for the GAFC300 body. The catalogue lists the same 1.0 MPa max pressure and -5 to 70 C temperature range for all three materials, so the choice is about your specific environment. Confirm the nylon bowl suits your shop's conditions before ordering.
