The AirTAC Airtac GAFC Air Service Unit GAFC400C15LW 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 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).
This GAFC400C15LW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a single T-bracket with quick clamps. The 1/2in port and 1810 g mass place it in the mid-size class, suited for machine headers feeding several actuators. It regulates to a lower 0.15-0.4 MPa (20-58 psi) band, with a 5 um element for finer filtration.
The metal bowl holds 100 cc of condensate, while the separate oil bowl holds 185 cc, so service intervals are practical for a production line. Air is filtered and set to pressure in the first body, then the lubricator adds metered oil mist downstream, keeping oil away from the regulator seat. The circular gauge reads in MPa/psi, matching the PT thread.

Constituent units, orderable separately as spares: GAFR400-15 filter & regulator, GAL400-15 lubricator — both share this body and port. A GAFC has two units, not three: the filter and the regulator are one body.
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.

The 5 um element and lower pressure range suit a precision pneumatic valve manifold on a packaging machine, where fine filtration protects small orifices and the 0.4 MPa ceiling matches a delicate actuator.
On a 1/2in conveyor header feeding several air cylinders, the 185 cc oil bowl keeps multiple lubricators topped up less often, while the metal bowl handles a washdown area without relying on a transparent bowl.
For a multi-station assembly bench with a 1/2in main line, this unit filters, regulates to a safe low pressure, and lubricates downstream tools. The 100 cc drain bowl and 1810 g mass indicate a permanent frame mount, not tubing support.
Choose the GAFC400 body when you need 1/2in ports and a 6000 L/min flow envelope (plotted at 0.7 MPa inlet) for a multi-station line. The C code specifies a metal bowl; the common specification of 1.0 MPa max and -5 to 70 C applies, so confirm the material suits your environment. The L type tops out at 0.4 MPa, so if the line may ever need more pressure, step up to the S type instead. The 5 um element traps finer particles for precision valves, but expect more frequent element service than a 40 um unit. A semi-auto drain dumps condensate on pressure drop, with a manual drain for on-demand use. The gauge is fitted with an MPa/psi scale for the PT thread. For spares, order the GAFR400-15 filter-regulator and GAL400-15 lubricator separately. If the line must stay oil-free, omit the lubricator and choose a plain GAFR. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
Quick checklist
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.
The GAFC400C15LW operates on air with a lower pressure range of 0.15-0.4 MPa (20-58 psi). Maximum supply pressure is 1.0 MPa (145 psi), with a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C and it must not freeze. It has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and uses ISO VG 32 or equivalent lubricant.
The C code specifies a metal bowl instead of the standard PC or optional nylon. The catalogue lists the same 1.0 MPa maximum pressure and -5 to 70 C temperature range for all bowl materials, so the choice is about the build environment. Confirm the metal bowl suits your surroundings, as the catalogue provides no impact, chemical, or heat resistance data for any material.
