The AirTAC Airtac GAFC Air Service Unit GAFC300N10ALNWK 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 3/8" ports, a 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).
This AirTAC GAFC300N10ALNWK 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. Air is cleaned and set to pressure in the first body, then the lubricator adds a controlled oil mist downstream, so oil never passes back through the regulator seat. With a 3/8in port and 1020 g mass, it suits panel or frame mounting rather than tubing support.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 5 um element for finer filtration. The nylon bowl is named as a build choice, but the catalogue gives no impact or chemical data, so confirm it suits your environment. An automatic drain clears condensate without an operator, and the 60 cc drain bowl plus 98 cc oil bowl set the service interval. No gauge is supplied; the 1/8in gauge connection allows one to be added later.

Constituent units, orderable separately as spares: GAFR300-10 filter & regulator, GAL300-10 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 5 um-filtered, lower-pressure supply to a precision pneumatic valve on a small assembly fixture, where fine particles could otherwise affect spool movement.
Lubricate the actuators on a short packaging conveyor line, using the automatic drain to handle condensate from a humid plant air supply without manual checks.
Set up a test bench for sensitive instruments at 0.4 MPa, with the 5 um element protecting the instrument internals and the lower-pressure range matching the required setpoint.
Choose this GAFC300N10ALNWK when your circuit needs a lower regulated ceiling of 0.4 MPa (20-58 psi) and fine 5 um filtration. The nylon bowl is specified by the N before the port, while the automatic drain (A) handles wet or unattended lines. The reverse-flow (reflux) valve is fitted per the K code, shown as a separate symbol in the catalogue. For a higher pressure range, step to the standard S type at 0.15-0.9 MPa; for coarser filtration, drop the W for a 40 um element. The gauge connection is 1/8in, and the PT thread carries an MPa/psi scale if you add a gauge. Spares are orderable as the GAFR300-10 filter & regulator and the GAL300-10 lubricator, both matching this body-port. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure carefully if you need to run near the ceiling.
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 GAFR300-10 filter-regulator on that branch instead of the full combination.
This lower-pressure F.R.L. combination 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 and needs ISO VG 32 lubricant. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g with a 3/8in port.
The N after the port code means no gauge is supplied with this unit. The GAFC300 body has a 1/8in gauge connection, so you can add a compatible gauge later if you need to read the set pressure. The PT thread on the connection uses an MPa/psi scale.
