About the Airtac GAFC Air Service Unit GAFC400C15ASNWK
This AirTAC GAFC400C15ASNWK 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 with quick clamps. Air is cleaned and set to pressure in the first body, then the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat. With a 1/2in port and 1810 g mass, this unit suits a machine header feeding several actuators, and it needs a proper panel or frame mount rather than support from the tubing.
The metal bowl (C code) holds 100 cc for condensate and 185 cc for oil, and the 5 um element traps finer particles than the standard 40 um grade, which matters for precision valves or instrument air. The working range is 0.15-0.9 MPa (20-130 psi), with max pressure 1.0 MPa (145 psi) and proof pressure 1.5 MPa (215 psi). No gauge is supplied, but the 1/4in gauge connection is there if you add one later. The automatic drain clears condensate without an operator, and the reverse-flow valve is fitted as an ordering option.

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 GAFC400C15ASNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line, where the 5 um element keeps fine particles out of pilot orifices and the regulated 0.15-0.9 MPa range covers typical actuator setpoints.
Machine tool header
Supply a CNC machine's air header that runs several cylinders and a blow-off nozzle, relying on the 100 cc condensate bowl and automatic drain to handle moisture from a wet compressor line.
Assembly station lubrication
Power a multi-station assembly fixture where each station has a small cylinder, and the 185 cc oil bowl keeps the lubricator filled for longer runs between service visits.
Is the Airtac GAFC Air Service Unit GAFC400C15ASNWK the Right Air-Prep Unit?
Choose this GAFC400C15ASNWK when you need 1/2in ports and a 1810 g body that feeds a multi-station line. The metal bowl is specified by the C code, and the common specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm the metal suits your surroundings rather than assuming it is tougher. The automatic drain (A) is decisive for unattended or wet lines. The 5 um element (W) filters finer than 40 um but needs more frequent service, and the PT thread carries a gauge scale in MPa and psi. The reverse-flow (reflux) valve is fitted per the K code, and the catalogue draws it as a separate pneumatic symbol. Spare parts are orderable as GAFR400-15 and GAL400-15. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan the supply near 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 GAFC400C15ASNWK FAQ
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). 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 unit weighs 1810 g. The port size is 1/2in, and the element grade is 5 um.
The N after the port code means no gauge is supplied with this unit. The gauge connection on the GAFC400 body is 1/4in, so you can fit a gauge there later if you need to read the set pressure. The PT thread version uses a gauge scale in MPa and psi when one is added.
