Airtac GAFC Air Service Unit GAFC400C15ASN
The AirTAC Airtac GAFC Air Service Unit GAFC400C15ASN is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1/2" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAFC Air Service Unit GAFC400C15ASN
This GAFC400C15ASN is an F.R.L. combination built as two pieces on one bracket: a filter-regulator body handles filtration and pressure control, then the lubricator adds a metered oil mist downstream. With a 1/2in port and a 1810 g mass, it suits medium-size machine headers where a single unit must feed several actuators.
The metal bowl holds 100 cc of condensate and the oil bowl 185 cc, so service intervals are long for a unit this size. It regulates from 0.15 to 0.9 MPa (20-130 psi) with a 40 um element, and the automatic drain clears water without an operator. No gauge is fitted; 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 GAFC400C15ASN Is Used
Machine Tool Lubrication
Feed a clean, regulated air supply with oil mist to a CNC lathe's tool changer and door cylinders, where consistent lubrication extends slide life.
Assembly Line Header
Supply a multi-station assembly line's pneumatic valves and actuators from one central point, with the automatic drain handling condensate from a busy production shift.
Packaging Equipment
Run a carton erector's cylinders and grippers on filtered, regulated, lubricated air, keeping cycle times stable with the 1/2in port feeding multiple devices.
Is the Airtac GAFC Air Service Unit GAFC400C15ASN the Right Air-Prep Unit?
Choose the GAFC400 body when a 1/2in port and a 6000 L/min flow envelope (plotted at 0.7 MPa inlet) match your line demand; step down to the GAFC300 for lighter duty. The metal bowl is specified by the C code, and the common specification of 1.0 MPa max and -5 to 70 C applies regardless of bowl material, so confirm the metal suits your environment. The automatic drain (A) removes condensate continuously, ideal for wet or unattended lines. The standard type (S) covers 0.15-0.9 MPa, and the 40 um element is the default grade. With no gauge supplied, the 1/4in connection is ready for an accessory. The PT thread carries an MPa/psi scale if you fit one. Spares are orderable as the GAFR400-15 filter-regulator and the GAL400-15 lubricator. Max supply of 1.0 MPa leaves only about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan inlet pressure close to 1.0 MPa 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 GAFC400C15ASN FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The C code specifies a metal bowl, which is a build choice for the unit's surroundings; the catalogue gives no performance difference between bowl materials, so confirm it suits your environment. The N after the port means no gauge is supplied, but the 1/4in gauge connection is ready for one to be added later.
