About the Airtac GAFC Air Service Unit GAFC400C10ASN
This GAFC400C10ASN 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 3/8in port and 1810 g mass place it in the mid-size class, a step up from the GAFC300's 1020 g for lines that need more condensate and oil capacity. Air enters the first body where solids and moisture are removed and pressure is set to 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 metal bowl is specified by the C code, and the common specification of 1.0 MPa (145 psi) maximum and -5 to 70 C applies regardless of bowl material. The automatic drain clears condensate without an operator, and the 100 cc drain bowl plus 185 cc oil bowl define the service interval. No gauge is supplied with this model; the 1/4in gauge connection on the GAFC400 body is available if a pressure readout is added later. The 40 um element handles standard shop air, and the catalogue flow curve is plotted to 6000 L/min at 0.7 MPa inlet for sizing reference.

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 GAFC400C10ASN Is Used
Machine tool lubrication
Feed a 3/8in line to a CNC spindle or slideway lubrication system where the 185 cc oil bowl supports longer runs between refills and the automatic drain handles condensate from wet shop air.
Assembly station air prep
Supply a multi-fixture assembly station with filtered, regulated air and a metered oil mist for pneumatic screwdrivers and push cylinders, with the metal bowl standing up to the factory floor environment.
Packaging line retrofits
Upgrade a packaging machine's 3/8in pneumatic circuit where the GAFC400's 6000 L/min envelope at 0.7 MPa inlet supports several actuators, and the automatic drain reduces maintenance on continuous runs.
Is the Airtac GAFC Air Service Unit GAFC400C10ASN the Right Air-Prep Unit?
Choose the GAFC400 body when a 3/8in port needs more capacity than the GAFC300's 3500 L/min envelope; the 100 cc drain bowl and 185 cc oil bowl reduce how often the unit is attended. The metal bowl is a build choice for the surrounding environment, and since the catalogue gives no impact or chemical data, confirm it suits your conditions. The automatic drain is fitted, so condensate clears itself without manual intervention. The standard type regulates from 0.15 to 0.9 MPa (20-130 psi), and the 40 um element is the default grade. The PT thread carries an MPa/psi gauge scale, but this model ships without a gauge, so the 1/4in connection is unused unless you add one. The two units are orderable separately as GAFR400-10 and GAL400-10, so a damaged bowl does not mean replacing the whole assembly. With a 1.0 MPa max supply, there is about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan the supply pressure accordingly if you need the full 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 GAFC400C10ASN FAQ
The GAFC400C10ASN operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 100 cc drain bowl and a 185 cc oil bowl, and the complete unit weighs 1810 g. The 3/8in port and 40 um element are standard for this body.
The C code specifies a metal bowl, which is a build choice for the installation environment; the catalogue does not provide impact or chemical resistance data, so confirm it suits your conditions. The N after the port code means no gauge is supplied, leaving the 1/4in gauge connection on the GAFC400 body available if you need to add a pressure readout later. The automatic drain is fitted regardless of bowl material.
