The AirTAC Airtac GAFC Air Service Unit GAFC40015LNK 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 - 0.4 MPa (20 - 58 psi).
This GAFC40015LNK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. The 1/2in port and 1810 g mass place it in the mid-size class, suited for feeding several actuators or a small machine header without occupying excessive rail space.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), with a 40 um element filtering the air before it reaches the lubricator. The 100 cc condensate bowl and 185 cc oil bowl define the service interval, while the reverse-flow valve is fitted per the K code. No gauge is supplied, so the 1/4in gauge connection is available if you need to read the set pressure.

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.

Feed a pneumatic press or clamping fixture that operates below 0.4 MPa, where the lower-pressure regulator provides finer adjustment within its band.
Supply oil-misted air to a short conveyor line with a few cylinders, using the 185 cc oil bowl to reduce refill frequency.
Prepare air for a lab test bench with sensitive components, relying on the 40 um element and the regulated 0.15-0.4 MPa output.
Choose the GAFC40015LNK when your line needs 1/2in ports and a regulated output capped at 0.4 MPa. The L type suits low-pressure circuits, but if the machine may ever require more than 0.4 MPa, select the standard S type instead. The PC bowl is the default build, and the semi-auto drain dumps condensate on pressure drop while the manual drain offers on-demand control. The 40 um element handles general shop air, and the PT thread matches standard local fittings. The K code adds the reverse-flow valve, which the catalogue shows as a separate pneumatic symbol. For spares, order the GAFR400-15 filter-regulator and the GAL400-15 lubricator separately. Since the lubricator adds oil mist, choose a plain GAFR if the line must stay oil-free. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure accordingly.
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 GAFC40015LNK operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It works in -5 to 70 C temperatures, uses ISO VG 32 lubricant, has a 100 cc drain bowl and 185 cc oil bowl, and weighs 1810 g.
The N after the port code means no gauge is supplied, so you would need to add one at the 1/4in gauge connection to read the set pressure. The K code indicates the reverse-flow valve is fitted, which the catalogue shows as a separate pneumatic symbol.
