The AirTAC Airtac GAFC Air Service Unit GAFC400N15ASN 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 GAFC400N15ASN is a two-piece F.R.L. combination: a filter-regulator body handles filtration and pressure control, and a separate lubricator adds oil mist downstream. With a 1/2in port and a 1810 g mass, it suits medium-sized machine headers where a panel mount is expected.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 40 um element filtering the air. The nylon bowl is specified by the N code, and the automatic drain clears condensate without operator attention. No gauge is fitted, so the 1/4in gauge connection is available if you add one later.

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 on a CNC lathe or milling machine, where the automatic drain handles condensate from compressed air used in coolant or chip-removal systems.
Supply a multi-operator assembly bench with regulated air for pneumatic screwdrivers and presses, relying on the 100 cc drain bowl to reduce maintenance frequency.
Run a bank of cylinders on a carton-sealing or palletizing line, using the 185 cc oil bowl to keep lubricator refills less frequent during long shifts.
Choose this GAFC400N15ASN for a 1/2in line needing standard regulation up to 0.9 MPa. The nylon bowl is a build choice, but the common specification (1.0 MPa max, -5 to 70 C) applies to all materials, so confirm it suits your surroundings. The automatic drain is ideal for wet or unattended lines, and the 40 um element handles general shop air. If you need finer filtration, select the W option for 5 um. The PT thread comes with a MPa/psi gauge scale, though this model ships without a gauge. For spares, order the GAFR400-15 filter-regulator and 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 working pressure range is 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 operates from -5 to 70 C and should not freeze. The drain bowl holds 100 cc and the oil bowl holds 185 cc. Recommended lubricant is ISO VG 32, and the unit weighs 1810 g.
The N after the port code means no gauge is supplied with this unit. The gauge connection on the GAFC400 body is 1/4in, so you can add a compatible gauge later if you need to read the set pressure directly.
