About the Airtac GAFC Air Service Unit GAFC400C10ASNK
The GAFC400C10ASNK is an F.R.L. combination that pairs a filter-regulator with a lubricator on a single T-shape bracket. Air enters the 3/8" port, gets filtered by the 40 um element, and is regulated to 0.15-0.9 MPa (20-130 psi) before the lubricator adds a controlled oil mist downstream. The metal bowl holds 100 cc of condensate, and the oil bowl holds 185 cc, with the whole unit weighing 1810 g.
Because the filter and regulator share one body, this is a two-piece assembly rather than a three-piece train, which means one less inter-unit joint to seal. The automatic drain clears condensate without an operator, and the reverse-flow (reflux) valve is fitted as an ordering difference. No gauge is supplied, but the 1/4" gauge connection allows one to be added later.

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 GAFC400C10ASNK Is Used
Precision Machining Center
Feed a CNC machining center's tool-changing mechanism with filtered and regulated air. The 3/8" port and 40 um element handle the modest flow, while the automatic drain keeps the metal bowl clear during long unattended runs.
Assembly Line Pneumatics
Supply a multi-station assembly line's pneumatic actuators and grippers. The 185 cc oil bowl ensures consistent lubrication over extended shifts, and the metal bowl suits the factory floor environment.
Packaging Equipment
Run a packaging machine's film-sealing and labeling stations with clean, regulated air. The 100 cc condensate bowl and automatic drain reduce maintenance checks, while the reverse-flow valve is fitted as specified.
Is the Airtac GAFC Air Service Unit GAFC400C10ASNK the Right Air-Prep Unit?
Choose this GAFC400 for a 3/8" port line that needs a metal bowl and automatic condensate removal. The metal bowl is a build choice for the specified environment, and the shared specification of 1.0 MPa max pressure and -5 to 70 C applies regardless of bowl material, so confirm compatibility for aggressive surroundings. The automatic drain suits unattended operation, while the 40 um element handles general workshop air; step up to the 5 um element if you need finer filtration. The PT thread comes with an MPa/psi gauge scale, though this model has no gauge fitted, so the 1/4" connection is there if you add one. The reverse-flow valve is included, and the unit is orderable as two spares: GAFR400-10 and GAL400-10. For oil-free air downstream, omit the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa 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 GAFC400C10ASNK FAQ
The GAFC400C10ASNK operates 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 has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and works in -5 to 70 C temperatures. Use ISO VG 32 lubricant. The unit has a 3/8" port, 40 um element, and a metal bowl.
The N in the code after the port means no gauge is supplied with this unit. The GAFC400 body has a 1/4" gauge connection, so you can add a circular gauge later if you need to read the set pressure. The PT thread option would use an MPa/psi scale on any gauge you install.
