The AirTAC Airtac GAFC Air Service Unit GAFC400N15SNW 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 - 0.9 MPa (20 - 130 psi).
This GAFC400N15SNW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. Air is cleaned and set to pressure first, then the lubricator adds a controlled oil mist last, so oil never travels back through the regulator seat. With a 1/2in port and 1810 g mass, it suits medium machine headers where a single point of air preparation feeds several actuators.
The nylon bowl holds 100 cc of condensate and the oil bowl 185 cc, so service intervals are practical for a busy line. The standard pressure range is 0.15-0.9 MPa (20-130 psi), and the 5 um element traps finer particles than the standard 40 um grade. No gauge is supplied with this model; the 1/4in gauge connection is ready for one 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 clean, regulated air supply with metered oil mist to a CNC lathe's tool changer and clamping cylinders, where the 5 um element protects precision spool valves from fine wear particles.
Mount on a central header serving multiple pneumatic screwdrivers on an electronics assembly line, using the 185 cc oil bowl to maintain consistent lubrication across several shifts.
Supply a carton erector's pneumatic cylinders and grippers, where the 100 cc condensate bowl and semi-auto drain handle moisture from a humid plant environment without constant operator attention.
Choose the GAFC400 body for a 1/2in port with a 6000 L/min flow envelope plotted at 0.7 MPa inlet, a step up from the GAFC300's 3500 L/min curve. The nylon bowl is a build choice; the catalogue lists the same 1.0 MPa max pressure and -5 to 70 C range for PC, metal, and nylon, so confirm the material suits your environment. This model has the semi-auto drain that dumps on pressure drop plus a manual drain for on-demand use, and the 5 um element is for finer filtration at the cost of more frequent element service. The PT thread carries a standard gauge scale in MPa/psi, but the N code means no gauge is fitted, so plan to add one on the 1/4in connection if operators need to see the setpoint. Spare parts are orderable separately as the GAFR400-15 filter-regulator and the GAL400-15 lubricator. Max supply of 1.0 MPa leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so set the supply near the maximum if you need the full output pressure.
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.
This F.R.L. combination operates on air with a standard pressure range of 0.15-0.9 MPa (20-130 psi), a max pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It is rated for -5 to 70 C and must not freeze. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The unit weighs 1810 g and has a 1/2in port.
The N after the port code specifies no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later if needed. The PT thread on this model would use a gauge with an MPa/psi scale. If you require a gauge fitted from the factory, choose a code without the trailing N.
