About the Airtac GAFC Air Service Unit GAFC400C15ASG
The GAFC400C15ASG is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. With a 1/2in port and a 1810 g mass, this unit suits medium-sized machine headers where a single air preparation point feeds several actuators. The metal bowl and automatic drain make it a fit-and-forget choice for continuous production lines.
Air enters the first body where a 40 um element removes solids and moisture, and the regulator sets pressure to your chosen point within 0.15-0.9 MPa (20-130 psi). The lubricator then adds a metered ISO VG 32 oil mist downstream, so oil never travels back through the regulator seat. The 100 cc condensate bowl and 185 cc oil bowl define the service interval, and the circular gauge reads in bar/MPa for the G thread.

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 GAFC400C15ASG Is Used
CNC Machine Header
Feed a 1/2in header supplying coolant valves and door cylinders on a CNC lathe. The 100 cc drain bowl and automatic drain handle condensate from continuous compressor run time.
Assembly Line Lubrication
Supply a multi-station assembly line where pneumatic screwdrivers need consistent oil mist. The 185 cc oil bowl keeps the lubricator filled across a full shift of intermittent tool use.
Packaging Machine Air Prep
Prepare air for a case packer's film-seal cylinders and grippers. The metal bowl resists accidental knocks on a crowded frame, and the bar/MPa gauge suits metric maintenance teams.
Is the Airtac GAFC Air Service Unit GAFC400C15ASG the Right Air-Prep Unit?
Choose the GAFC400C15ASG when you need a 1/2in port with a metal bowl and automatic drain. The G thread specifies a bar/MPa gauge scale, which operators in metric plants will read directly. The 40 um element handles general workshop air; step to the 5 um W option if you feed precision valves or instrument air, accepting more frequent element changes. The automatic drain clears condensate without an operator, ideal for unattended shifts. The two units are separately orderable as GAFR400-15 and GAL400-15, so a damaged bowl or clogged element does not force a full replacement. For oil-free lines, omit the lubricator and choose a plain GAFR filter-regulator instead. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan inlet pressure 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 GAFC400C15ASG FAQ
The GAFC400C15ASG operates at 0.15-0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. It works in -5 to 70 C temperatures and requires ISO VG 32 lubricant. The unit has a 100 cc drain bowl, 185 cc oil bowl, and weighs 1810 g. The 40 um filter element handles standard workshop air.
The C code specifies a metal bowl, a build choice for environments where the bowl may face physical contact. The catalogue gives no impact or chemical resistance data, so confirm the material suits your surroundings. The G thread means the ports use G-thread fittings and the circular gauge reads in bar/MPa, matching metric pressure gauges.
