About the Airtac GAFC Air Service Unit GAFC400C10SNWK
This AirTAC GAFC400C10SNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a single T-bracket with quick clamps. The 3/8in port and 1810 g mass place it in the mid-size class, suited for machine headers or multi-station lines where a compact footprint matters.
Air enters the first body where the 5 um element traps fine particles and the regulator sets pressure from 0.15 to 0.9 MPa (20-130 psi). The lubricator then adds a metered oil mist downstream, so oil never travels back through the regulator seat. The metal bowl holds 100 cc of condensate, while the oil bowl holds 185 cc, reducing how often an operator needs to check levels.

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 GAFC400C10SNWK Is Used
CNC Coolant Systems
Feed a 3/8in line to a CNC machine's coolant valve manifold. The 5 um element protects precision solenoid valves from fine wear particles, while the lubricator keeps the valve spools moving freely.
Assembly Station Headers
Mount on a panel above a multi-station assembly bench. The 185 cc oil bowl supports several pneumatic screwdrivers or torque tools through a shift, reducing oil refill stops.
Packaging Line Air Prep
Install before a packaging machine's film-seal cylinders. The 100 cc metal drain bowl handles condensate from humid plant air, and the 1810 g body stays stable on a frame mount.
Is the Airtac GAFC Air Service Unit GAFC400C10SNWK the Right Air-Prep Unit?
Choose the GAFC400 body for a balance of capacity and footprint: the 100 cc drain bowl and 185 cc oil bowl serve medium-duty lines, while the 3/8in port suits branch circuits from a larger header. The metal bowl is specified by the C code; the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of material, so confirm the metal suits your environment. With the N after the port, no gauge is supplied; the 1/4in gauge connection allows adding one later. The 5 um element (W) traps finer particles than the standard 40 um, but requires more frequent service. The semi-auto drain dumps condensate on pressure drops, with a manual backup for on-demand use. The reverse-flow (reflux) valve is fitted per the K code. Spare parts are orderable as GAFR400-10 and GAL400-10. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan 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 GAFC400C10SNWK FAQ
This F.R.L. combination operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum supply of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It is rated for -5 to 70 C and uses ISO VG 32 lubricant. The metal drain bowl holds 100 cc, the oil bowl holds 185 cc, and the complete unit weighs 1810 g.
The C code specifies a metal bowl, which is a build choice for the unit's surroundings; the catalogue does not publish different temperature or pressure ratings for bowl materials, so confirm compatibility with your environment. The N after the port means no gauge is supplied, but the 1/4in gauge connection is there if you add one. The K code adds a reverse-flow (reflux) valve, which the catalogue shows as a separate pneumatic symbol.
