About the Airtac GAFC Air Service Unit GAFC400N15ASWK
This GAFC400N15ASWK 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. The 1/2in port and 1810 g mass place it in the mid-size class, suitable for a machine header feeding several actuators rather than a single small cylinder.
The air is filtered and regulated in the first body, then the lubricator adds a metered oil mist downstream, 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 holds 100 cc of condensate while the oil bowl holds 185 cc, reducing how often someone must attend the unit.

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 GAFC400N15ASWK Is Used
Precision valve stations
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element protects fine internal clearances and the automatic drain keeps condensate from reaching sensitive components.
Machine tool coolant systems
Supply a 1/2in header on a CNC machine that runs multiple air cylinders, where the 185 cc oil bowl supports continuous lubrication for extended shifts without frequent refills.
Assembly line automation
Power a multi-station assembly fixture with several actuators, relying on the 100 cc condensate bowl and automatic drain to maintain air quality in a busy production environment.
Is the Airtac GAFC Air Service Unit GAFC400N15ASWK the Right Air-Prep Unit?
Choose the GAFC400 body when a 1/2in port and 1810 g mass fit your panel layout; the flow curve is plotted to 6000 L/min at 0.7 MPa inlet, so compare it against the GAFC300's 3500 L/min envelope if you need less capacity. The nylon bowl is specified here, and the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of material, so confirm nylon suits your environment. The A code means an automatic drain clears condensate without an operator, and the 5 um element traps finer particles for precision valves, though it will need more frequent service than a 40 um unit. A circular gauge is fitted with an MPa/psi scale for the PT thread, and the K code indicates the reverse-flow valve is included. The filter-regulator and lubricator are orderable separately as GAFR400-15 and GAL400-15. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan a supply near 1.0 MPa if you need the full output.
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 GAFC400N15ASWK FAQ
This unit works with air 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 and requires ISO VG 32 lubricant. The drain bowl holds 100 cc and the oil bowl holds 185 cc, with a total weight of 1810 g.
The nylon bowl is a material choice that shares the same 1.0 MPa max pressure and -5 to 70 C temperature range as other bowl options, so confirm it fits your environment. The 5 um element traps finer particles than the standard 40 um grade, which suits precision equipment but requires more frequent element service.
