Airtac GAFC Air Service Unit GAFC400N10ASNWK
The AirTAC Airtac GAFC Air Service Unit GAFC400N10ASNWK 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 3/8" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC400N10ASNWK
This GAFC400 F.R.L. combination joins a filter-regulator and a lubricator on a single T-bracket with quick clamps, so the air is cleaned, set to pressure, then oil-misted in the last stage. The 3/8in port and 1810 g mass place it in the mid-size class, suited to a machine header or a small multi-station line rather than a single actuator.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 5 um element trapping fine particles for sensitive valves. The nylon bowl holds 100 cc of condensate, while the oil bowl holds 185 cc, and the automatic drain clears water without an operator. No gauge is supplied, 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 GAFC400N10ASNWK Is Used
Precision valve control
Feed a bank of pneumatic valves on a CNC machine with the 5 um element filtering fine particles before the regulator sets a stable pressure.
Small assembly line header
Supply a multi-station assembly bench where the 3/8in port and 185 cc oil bowl keep several small cylinders lubricated between refills.
Packaging machine air prep
Mount on a carton erector to filter and regulate the air feeding grippers and pushers, with the automatic drain handling condensate from a humid plant line.
Is the Airtac GAFC Air Service Unit GAFC400N10ASNWK the Right Air-Prep Unit?
Choose the GAFC400 when a 3/8in port and a 6000 L/min flow envelope (plotted at 0.7 MPa inlet) fit the duty, stepping down to the GAFC300 for lighter lines or up to the GAFC500 for a 3/4in port. The nylon bowl is a build choice, but the shared specification does not change with it, so confirm it suits your surroundings. The automatic drain handles wet or unattended lines, while the 5 um element demands more frequent service than the standard 40 um grade. The reverse-flow (reflux) valve is fitted, and the PT thread carries the default MPa/psi gauge scale. Spares are the GAFR400-10 filter-regulator and GAL400-10 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan the inlet pressure carefully if you need the full regulated output.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400N10ASNWK FAQ
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It is rated for -5 to 70 C, uses a 5 um element, and the drain bowl holds 100 cc while the oil bowl holds 185 cc. Recommended lubricant is ISO VG 32, and the unit weighs 1810 g.
The N after the port code means no gauge is supplied, so you cannot read the set pressure directly. If you need one, the gauge connection on the GAFC400 is 1/4in, and adding a gauge lets you verify the regulated output at a glance.
