About the Airtac GAFC Air Service Unit GAFC400N10SNW
This AirTAC GAFC400N10SNW is a two-piece F.R.L. combination built for a 3/8in port. The first body houses the filter and regulator together, so air is cleaned and set to pressure in one step, then the lubricator adds a metered oil mist downstream. It operates across 0.15-0.9 MPa (20-130 psi) and uses a 5 um element for finer filtration.
The nylon bowl holds 100 cc of condensate and the oil bowl 185 cc, with a total mass of 1810 g. Because the filter and regulator share one body, there is one less inter-unit joint to seal compared with a three-piece filter-regulator-lubricator train. The catalogue flow curve for this body is plotted to 6000 L/min at 0.7 MPa inlet, which serves as a sizing envelope rather than a rated capacity.

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 GAFC400N10SNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station. The 5 um element protects fine internal clearances, while the regulator holds the set pressure for consistent actuator response.
Packaging line tensioning
Supply a film-tensioning cylinder on a packaging machine. The 185 cc oil bowl keeps the cylinder lubricated through long shifts, and the semi-auto drain clears condensate each time the line stops.
Machine tool coolant valve
Operate a coolant shut-off valve on a small CNC machine. The 3/8in port matches common valve actuators, and the 100 cc condensate bowl handles moisture from a humid compressor supply.
Is the Airtac GAFC Air Service Unit GAFC400N10SNW the Right Air-Prep Unit?
Choose the GAFC400 body when a 3/8in port and a 1810 g unit suit your panel layout; it sits between the GAFC300 (1020 g, 3500 L/min envelope) and the GAFC500 (1910 g, 7000 L/min envelope). The nylon bowl is a build choice, and since the shared specification of 1.0 MPa max and -5 to 70 C applies to all materials, confirm it suits your environment. The semi-auto drain dumps condensate when pressure drops, while the manual drain gives on-demand control. No gauge is supplied, so the 1/4in gauge connection is where you would add one to read the set pressure. The 5 um element traps finer particles than the standard 40 um, at the cost of more frequent element service. Spare parts are orderable as GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, there is 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 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 GAFC400N10SNW FAQ
This F.R.L. combination works with air at 0.15-0.9 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 needs ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g. The 5 um element filters the air before it reaches the regulator seat.
The N after the port code means no gauge is supplied with this unit. The GAFC400 body has a 1/4in gauge connection, so you can fit a separate pressure gauge there to read the regulated output. The default PT thread uses a gauge scale in MPa and psi if you add one.
