About the Airtac GAFC Air Service Unit GAFC300N08ASNW
This AirTAC GAFC300N08ASNW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a T-bracket with quick clamps. The 1/4in port and 1020 g mass place it in the mid-size class, suited for a single machine station or a small pneumatic circuit.
The filter removes solids and water, the regulator holds the set pressure, and the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat. It operates from 0.15 to 0.9 MPa (20-130 psi) with a 5 um element, and the nylon bowl is a build choice - confirm it suits your environment, as the -5 to 70 C rating is shared across all bowl materials.

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 GAFC300N08ASNW Is Used
Precision valve control
Feed a 5 um-filtered, regulated air supply to a precision pneumatic valve on a CNC tool changer, where fine particles could cause sticking.
Single-station assembly
Power a dedicated clamping fixture on an assembly bench, with the automatic drain handling condensate from a humid plant line.
Test rig air prep
Supply clean, pressure-set air to a leak-test fixture, where the 5 um element protects sensitive gauges and the lubricator oils the test cylinder.
Is the Airtac GAFC Air Service Unit GAFC300N08ASNW the Right Air-Prep Unit?
Choose this GAFC300N08ASNW when you need a 1/4in port with a 5 um element for finer filtration, and an automatic drain that clears condensate without an operator. The nylon bowl is specified by the N before the port code; the gauge is omitted (N after the port), so the 1/8in gauge connection is available if you add one later. The PT thread carries an MPa/psi scale if a gauge is fitted. For oil-free lines, omit the lubricator and select a plain GAFR300-08 filter-regulator instead; spares for this unit are GAFR300-08 and GAL300-08.
Max supply of 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the inlet pressure accordingly if you need the full 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.
Airtac GAFC Air Service Unit GAFC300N08ASNW FAQ
This F.R.L. combination works from 0.15 to 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 operates from -5 to 70 C, uses ISO VG 32 lubricant, has a 60 cc drain bowl and 98 cc oil bowl, and weighs 1020 g. The 5 um element and automatic drain are fitted.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so you can add a circular gauge later if you need to read the set pressure directly. The PT thread option uses an MPa/psi scale.
