About the Airtac GAFC Air Service Unit GAFC400N15ASNWK
This GAFC400N15ASNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket. The 1/2in port size and 1810 g mass place it in the mid-size class, suited for feeding a machine header or several actuators from one supply point. Air is cleaned and set to pressure in the first body, then the lubricator introduces a metered oil mist downstream, so oil never travels back through the regulator seat.
It operates over the standard 0.15-0.9 MPa (20-130 psi) range with a 5 um element for finer filtration. The nylon bowl holds 100 cc of condensate and the oil bowl 185 cc, which together set the service rhythm for the unit. No gauge is fitted, so the set pressure cannot be read without adding one to the 1/4in gauge connection.

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 GAFC400N15ASNWK Is Used
Precision valve control
Feed a bank of pneumatic valves on a packaging line with the 5 um element trapping fine particles that could stick spools or seats.
Machine tool lubrication
Supply a CNC machine's way-lubrication system with the 185 cc oil bowl sized for extended runs between refills.
Multi-station assembly
Run a conveyor transfer station with several cylinders, where the automatic drain keeps condensate out of downstream valves without daily checks.
Is the Airtac GAFC Air Service Unit GAFC400N15ASNWK the Right Air-Prep Unit?
Choose this GAFC400N15ASNWK when you need 1/2in ports and the 5 um element for finer particles, at the cost of more frequent element service than the standard 40 um grade. The automatic drain clears condensate without an operator, which suits unattended or wet lines. The nylon bowl is a build choice, not a performance upgrade: the 1.0 MPa (145 psi) maximum and -5 to 70 C range apply to all bowl materials, so confirm nylon suits your surroundings. The reverse-flow (reflux) valve is fitted, and the PT thread carries a gauge scale in MPa/psi if you add a gauge later. The filter-regulator and lubricator are orderable separately as GAFR400-15 and GAL400-15. 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 supply pressure accordingly.
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 GAFC400N15ASNWK FAQ
This F.R.L. combination works with air at 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The temperature range is -5 to 70 C, and it uses ISO VG 32 or equivalent lubricant. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The N after the port code means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later. Without one, the operator cannot read the set pressure directly on the unit.
