About the Airtac GAFC Air Service Unit GAFC400N10ASN
This AirTAC GAFC400N10ASN is a two-piece F.R.L. combination: a filter and regulator share one body, and a lubricator mounts beside it on a T-bracket with quick clamps. The 3/8in port and 1810 g mass place it in the mid-size class, suited to a machine header feeding several actuators rather than a single small cylinder. Air enters the first body where solids and moisture are removed and pressure is set to the 0.15-0.9 MPa (20-130 psi) band, then the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat.
The nylon bowl is specified by the N before the port code; the catalogue lists the same 1.0 MPa (145 psi) maximum and -5 to 70 C range for PC, metal and nylon bowls, so confirm the material suits your washdown or solvent exposure before ordering. The automatic drain (A) clears condensate from the 100 cc bowl without operator action, which suits a line that runs unattended between shifts. No gauge is supplied, but the 1/4in gauge connection is ready for a field-installed unit if you need to read the set pressure.

Constituent units, orderable separately as spares: GAFR400-10 filter & regulator, GAL400-10 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.

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 GAFC400N10ASN Is Used
CNC spindle air
Feed a 3/8in line to a CNC spindle air curtain or tool changer, where the 0.15-0.9 MPa range covers typical actuation and the automatic drain keeps the 100 cc bowl clear during long cycles.
Packaging line manifolds
Supply a multi-station packaging conveyor manifold that runs several small cylinders and sensors; the 1810 g unit mounts on a frame rail and the 185 cc oil bowl sustains lubrication across a full shift.
Assembly station headers
Power a bench assembly station with a 3/8in header feeding a torque tool and a parts pusher, where the 6000 L/min envelope at 0.7 MPa inlet gives ample margin for simultaneous motion.
Is the Airtac GAFC Air Service Unit GAFC400N10ASN the Right Air-Prep Unit?
Choose the GAFC400 body when your line needs the 3/8in port and the 6000 L/min plotted flow envelope at 0.7 MPa inlet; step down to a GAFC300 for lighter duty or up to a GAFC500 for a 3/4in header. The nylon bowl is a build choice, not a performance upgrade, and the automatic drain removes the need to manually dump the 100 cc condensate bowl. The standard S type regulates from 0.15 to 0.9 MPa (20-130 psi), and the 40 um element handles general shop air; select the W option for 5 um filtration if you feed precision valves. This unit has no gauge, so add one to the 1/4in connection if operators must verify the setpoint. Spares are orderable as the GAFR400-10 filter & regulator and the GAL400-10 lubricator. 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 maximum if you truly 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 GAFC400N10ASN FAQ
The GAFC400N10ASN operates from 0.15 to 0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. It is rated for -5 to 70 C and uses ISO VG 32 oil in the lubricator. The drain bowl holds 100 cc and the oil bowl 185 cc, with a total weight of 1810 g.
The N after the port code means no gauge is supplied, so you cannot read the set pressure without adding one. The GAFC400 body has a 1/4in gauge connection, which is the standard port for a field-installed pressure gauge if you need to verify the 0.15-0.9 MPa setting.
