The AirTAC Airtac GAFC Air Service Unit GAFC40015SK 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 - 0.9 MPa (20 - 130 psi).
This 1/2in F.R.L. combination pairs a filter-regulator with a lubricator on a T-shape bracket, so air is cleaned and set to pressure in the first body before a metered oil mist is added downstream. The 40 um element handles standard shop air, and the semi-auto drain dumps condensate each time pressure drops while the manual drain gives on-demand control.
Weighing 1810 g with a 100 cc condensate bowl and a 185 cc oil bowl, the GAFC400 suits medium-sized machines where the lubricator's oil capacity keeps refills infrequent. The circular gauge reads in MPa and psi for the default PT thread, and the reverse-flow valve is fitted as a catalog option.

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 1/2in header supplying coolant valves and spindle air on a CNC lathe, where the 185 cc oil bowl keeps lubrication consistent across a shift.
Power a case erector's pneumatic cylinders and sensors on a packaging line, with the 100 cc drain bowl handling condensate from a humid plant air supply.
Supply filtered, regulated air to pneumatic clamps on a multi-station assembly fixture, where the 40 um element protects precision valves and the gauge lets operators verify setpoint.
Choose the GAFC400 when a 1/2in port and the 6000 L/min plotted flow envelope at 0.7 MPa inlet match your line. The PC bowl is the standard build, while the 100 cc drain bowl and 185 cc oil bowl set the service rhythm. The semi-auto plus manual drain pair covers both automatic dumping and operator-triggered purging, and the 40 um element suits general pneumatic duty. The fitted gauge reads MPa and psi, and the reverse-flow valve is included per the K code. For spares, order the GAFR400-15 filter-regulator and the GAL400-15 lubricator separately. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 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 GAFC40015SK operates from 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). 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 K code indicates the reverse-flow (reflux) valve is fitted. The catalog shows this as a separate pneumatic symbol, and it is included as an ordering option on this unit. The valve is part of the assembly as delivered.
