About the Airtac GAFC Air Service Unit GAFC400N10ASK
This AirTAC GAFC400N10ASK is a two-piece F.R.L. combination: the filter and regulator share one body, and a lubricator is mounted on the same T-bracket. Air is cleaned and set to pressure in the first unit, then the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat. With a 3/8" port and 1810 g mass, it suits mid-size machine headers where a panel or frame mount is expected rather than tubing support.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element and an automatic drain. The nylon bowl holds 100 cc of condensate, while the separate oil bowl holds 185 cc, and the circular gauge reads in MPa/psi for the default PT thread. A reverse-flow (reflux) valve is fitted, and the catalogue flow curve for this body is plotted to 6000 L/min at 0.7 MPa inlet as a sizing envelope.

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 GAFC400N10ASK Is Used
CNC spindle lubrication
Feed a 3/8" line to a CNC spindle air system where the regulator holds 0.5 MPa and the lubricator meters oil to way lube points. The 185 cc oil bowl supports longer runs between refills.
Assembly station air prep
Mount on a panel above a multi-station assembly bench, supplying filtered and regulated air to pneumatic screwdrivers and pick-and-place grippers. The automatic drain keeps the 100 cc bowl clear during shifts.
Packaging machine header
Use on a packaging line's main header to condition air for cylinders and valves. The 3/8" port and 6000 L/min envelope at 0.7 MPa inlet support several actuators, while the reflux valve is fitted for reverse-flow conditions.
Is the Airtac GAFC Air Service Unit GAFC400N10ASK the Right Air-Prep Unit?
Choose the GAFC400N10ASK when you need a 3/8" port with a 100 cc condensate bowl and 185 cc oil bowl, giving fewer service stops than the GAFC300's 60 cc and 98 cc bowls. The nylon bowl is specified by the N before the port, and the automatic drain (A) clears condensate without an operator, which suits wet or unattended lines. The standard type (S) regulates from 0.15 to 0.9 MPa, and the fitted gauge reads in MPa/psi on the PT thread; the 40 um element is the default, and the K code adds the reverse-flow valve. Replacement units are orderable separately as the GAFR400-10 filter & regulator and the GAL400-10 lubricator, so a clogged element or damaged bowl does not mean replacing the whole assembly. Since the lubricator adds oil mist, choose a plain GAFR filter-regulator if the line must stay oil-free. Max supply is 1.0 MPa, which leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan a supply near 1.0 MPa if you need 0.9 MPa out.
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 GAFC400N10ASK FAQ
The GAFC400N10ASK operates from 0.15 to 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). Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The condensate bowl holds 100 cc and the oil bowl holds 185 cc, with a total weight of 1810 g. The 40 um element filters the air, and the automatic drain clears condensate without operator intervention.
The K code indicates the reverse-flow (reflux) valve is fitted to this GAFC400N10ASK. The catalogue shows it as a separate pneumatic symbol in the circuit. This is an ordering difference from models without the K code, which do not have the valve attached.
