The AirTAC Airtac GAFC Air Service Unit GAFC300N15ASNWK 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 GAFC300 F.R.L. combination pairs a filter-regulator body with a lubricator on a single T-bracket, so the 1/2in port unit delivers air that is cleaned, set to 0.15-0.9 MPa (20-130 psi), and then oil-misted in that order. The 5 um element traps fine particles for sensitive valves, while the nylon bowl and automatic drain handle condensate without operator attention.
The two-piece build means the filter and regulator share one housing, cutting the inter-unit joints compared to a three-body train. With a 60 cc drain bowl and 98 cc oil bowl, this 1020 g unit suits medium-sized machines where the automatic drain reduces maintenance rounds. The reverse-flow valve is fitted, and the gauge connection is 1/8in if you add one later.

Constituent units, orderable separately as spares: GAFR300-15 filter & regulator, GAL300-15 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 bank of pilot-operated valves on a packaging line where the 5 um element protects fine orifices from wear and the automatic drain keeps the supply dry.
Supply a CNC lathe's way lubrication system with metered oil mist, while the regulator holds a stable 0.4 MPa setpoint for consistent dosing.
Run a series of 1/2in port cylinders on an automotive assembly fixture, where the 98 cc oil bowl supports extended shifts between refills.
Choose this GAFC300N15ASNWK when you need a 1/2in port with a 5 um element and automatic drain. The nylon bowl is a build choice - the 1.0 MPa (145 psi) max and -5 to 70 C range apply to all bowl materials, so confirm nylon suits your environment. The no-gauge version leaves the 1/8in connection open for your own gauge, and the PT thread reads MPa/psi if fitted. Spare parts are GAFR300-15 and GAL300-15, both orderable separately.
A 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near the maximum if you need the full regulated output.
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 GAFR300-15 filter-regulator on that branch instead of the full combination.
This F.R.L. combination operates at 0.15-0.9 MPa (20-130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g with a 1/2in port.
The N after the port code means no gauge is supplied, leaving a 1/8in connection on the GAFC300 body. You can fit your own gauge there, but without one the set pressure cannot be read directly on the unit. The PT thread option would use an MPa/psi scale if you add a gauge.
