About the Airtac GAFC Air Service Unit GAFC400C15LK
This AirTAC GAFC400C15LK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 1/2in port and 1810 g mass place it in the mid-size class, suited to feeding a multi-axis machine or a small production line. It carries a 40 um element and a circular gauge reading MPa/psi.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), with a 1.0 MPa (145 psi) maximum supply. Its 100 cc condensate bowl and 185 cc oil bowl define the service rhythm; the metal bowl is specified by the C code, and the reverse-flow (reflux) valve is fitted as an ordering option. The semi-auto drain dumps on pressure drop, while the manual drain works on demand.

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 GAFC400C15LK Is Used
Precision Drilling Jig
Feed a multi-spindle drilling jig with regulated air at 0.3 MPa, where the lower-pressure range prevents over-force on small workpieces.
Assembly Line Pallet Stop
Power pallet stops on a conveyor assembly line, using the semi-auto drain to clear condensate during frequent pressure drops.
Test Bench Air Supply
Supply a test bench with clean, lubricated air at a set 0.35 MPa for checking pneumatic components without exceeding their rated pressure.
Is the Airtac GAFC Air Service Unit GAFC400C15LK the Right Air-Prep Unit?
Choose this GAFC400C15LK when your circuit needs a regulated 0.15-0.4 MPa band and a 1/2in port. The metal bowl is a build choice; confirm it suits your environment, as the catalogue gives no material-specific ratings. The semi-auto plus manual drain pair suits attended stations, and the fitted gauge shows MPa/psi. The reverse-flow (reflux) valve is included per the K code. If the line must stay oil-free, omit the lubricator and select a plain GAFR400-15 filter-regulator instead; the GAL400-15 lubricator is separately orderable. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the range.
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 GAFC400C15LK FAQ
It operates on air, with a lower-pressure range of 0.15-0.4 MPa (20-58 psi). Maximum pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g. Use ISO VG 32 lubricant.
The K code specifies that a reverse-flow (reflux) valve is fitted. It appears as a separate pneumatic symbol in the catalogue. The unit also has a metal bowl (C) and a lower-pressure regulator (L), with a 1/2in port.
