The AirTAC Airtac GAFC Air Service Unit GAFC300N08ALNW 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 1/4" ports, a 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).
This GAFC300N08ALNW is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator mounts beside it on a T-bracket. Air enters the 1/4in port, passes through the 5 um element, gets regulated to a lower 0.15-0.4 MPa (20-58 psi) band, then receives a metered oil mist from the lubricator before exiting. The nylon bowl holds 60 cc of condensate, while the separate oil bowl holds 98 cc.
The automatic drain clears collected water without operator intervention, which suits wet or unattended lines. With no gauge fitted, the 1/8in gauge connection on the GAFC300 body allows adding one later if needed. At 1020 g, this unit needs a proper panel or frame mount rather than support from tubing alone.

Specifications follow the official AirTAC GAFC catalogue (pages 219-220). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFC300 is 1/8" if you add one.

Constituent units, orderable separately as spares: GAFR300-08 filter & regulator, GAL300-08 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.

Regulate supply to precision air bearings on a measuring machine, where the 0.15-0.4 MPa band prevents over-pressurizing sensitive surfaces and the 5 um element keeps fine particles away.
Feed a gentle blow-off station for cleaning finished parts before packaging, using the lower pressure range to avoid damaging delicate surfaces while the automatic drain handles wet compressor air.
Power a small lab fixture or test rig that needs clean, regulated air below 0.4 MPa, with the 1/4in port suiting compact bench setups and the nylon bowl offering a lightweight build.
Choose the GAFC300N08ALNW when your circuit needs a 1/4in port and a regulated ceiling of 0.4 MPa, not the standard 0.9 MPa. The L type is for low-pressure duties like air bearings or delicate blow-off; if a machine may ever require more than 0.4 MPa, select the standard S type instead. The 5 um element traps finer particles than the standard 40 um, which protects precision valves but requires more frequent element service. The automatic drain suits condensate-heavy environments, while the nylon bowl is a material choice that shares the same 1.0 MPa max and -5 to 70 C rating as PC or metal. The PT thread carries a gauge scale in MPa/psi if you add a gauge to the 1/8in connection. Spares are orderable as GAFR300-08 and GAL300-08. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above this unit's 0.4 MPa top setting.
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 GAFR300-08 filter-regulator on that branch instead of the full combination.
This 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 handles temperatures from -5 to 70 C, uses ISO VG 32 oil in the lubricator, and weighs 1020 g. The drain bowl holds 60 cc and the oil bowl holds 98 cc. The 5 um element filters air before regulation, and the automatic drain clears condensate without manual attention.
The N after the port code means no gauge is supplied, so you cannot read the set pressure directly on the unit. The GAFC300 body has a 1/8in gauge connection where you can add a circular gauge later if needed. The PT thread means any gauge you add should read in MPa/psi to match the standard scale.
