About the Airtac GAFC Air Service Unit GAFC400N15SNK
This GAFC400N15SNK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. The 1/2in port and 1810 g mass place it in the mid-size class, suited for distribution to multiple actuators or a small machine header rather than a single cylinder.
Air enters the first body where the 40 um element removes solids and moisture, and the regulator sets pressure within 0.15-0.9 MPa (20-130 psi). The lubricator then adds a controlled oil mist downstream, so oil never travels back through the regulator seat. The nylon bowl is specified by the N code; the catalogue gives no material-specific ratings, so confirm it suits your environment. No gauge is supplied, but the 1/4in 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 GAFC400N15SNK Is Used
Machine tool lubrication
Feed a 1/2in line to a CNC lathe's tool changer and door cylinders, where the regulated 0.15-0.9 MPa range covers typical actuation and the oil mist keeps sliding ways moving freely.
Assembly station air prep
Supply a multi-operator workbench with filtered, pressure-set air for pneumatic screwdrivers and push-in fittings, with the 185 cc oil bowl reducing how often the lubricator needs topping up.
Packaging line transfer
Operate a section of belt diverters and stops on a packaging line, where the 100 cc condensate bowl captures moisture from a humid plant and the semi-auto drain clears it at each pressure drop.
Is the Airtac GAFC Air Service Unit GAFC400N15SNK the Right Air-Prep Unit?
Choose the GAFC400 body for medium-flow circuits; its catalogue flow curve is plotted to 6000 L/min at 0.7 MPa inlet, roughly 70% more than the GAFC300's 3500 L/min envelope. The N code specifies a nylon bowl, while the blank default is PC and C is metal; all share the same 1.0 MPa maximum and -5 to 70 C rating. This unit has the semi-auto drain (dumps on pressure drop) plus a manual drain for on-demand use, and the 40 um element is the standard grade. The K suffix means the reverse-flow (reflux) valve is fitted, shown as a separate symbol in the catalogue. Spare parts are orderable as GAFR400-15 and GAL400-15. 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 inlet pressure carefully if you need the full output.
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 GAFC400N15SNK FAQ
It is an F.R.L. combination with a 1/2in port, working pressure 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 40 um element, 100 cc drain bowl, 185 cc oil bowl, and weight 1810 g. Use ISO VG 32 oil in the lubricator.
The N after the port code means no gauge is supplied; the GAFC400 body has a 1/4in gauge connection if you add one later. The K code means the reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol. The nylon bowl is specified by the N before the port code.
