Airtac GAFC Air Service Unit GAFC400N15SW
The AirTAC Airtac GAFC Air Service Unit GAFC400N15SW is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1/2" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC400N15SW
This AirTAC F.R.L. combination pairs a filter-regulator with a lubricator on a single T-bracket, so the 1/2in port unit delivers cleaned, pressure-set air with a metered oil mist added last. The 5 um element traps fine particles before the regulator stage, and the nylon bowl holds 100 cc of condensate while the oil bowl holds 185 cc.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum. At 1810 g, this GAFC400 needs a proper panel or frame mount rather than tubing support. The circular gauge reads in MPa/psi, matching the PT thread, and the semi-auto drain dumps condensate each time pressure drops.

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 GAFC400N15SW Is Used
Precision valve stations
Feed a bank of 1/2in solenoid valves on a packaging line where the 5 um element protects tight spool clearances from fine abrasive dust.
Machine tool lubrication
Supply a CNC lathe's way-lubrication system with filtered, regulated air carrying a controlled oil mist to slideways and guide surfaces.
Assembly fixture circuits
Power multiple pneumatic clamps on a dedicated assembly fixture where the 100 cc condensate bowl extends time between drain checks.
Is the Airtac GAFC Air Service Unit GAFC400N15SW the Right Air-Prep Unit?
Choose the GAFC400 when a 1/2in port with a 6000 L/min flow envelope at 0.7 MPa inlet suits your line. The nylon bowl is a build choice - the catalogue gives no impact or chemical data, so confirm it fits your surroundings. The semi-auto drain clears on pressure drops, while the manual drain works on demand; the 5 um element suits precision valves but needs more frequent service than the standard 40 um. The GAFR400-15 filter-regulator and GAL400-15 lubricator are separately orderable spares. Max supply of 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the regulated range.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400N15SW FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Operating temperature is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The N code specifies a nylon bowl instead of the standard polycarbonate. The catalogue lists no performance difference - the 1.0 MPa maximum and -5 to 70 C range are identical for both materials. Confirm nylon suits your specific environment, as no impact or chemical resistance data is published.
