The AirTAC Airtac GAFC Air Service Unit GAFC300C08S 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 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GAFC300C08S is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. Air enters the 1/4in port, gets filtered and regulated to 0.15-0.9 MPa (20-130 psi), then oil mist is added downstream. The metal bowl holds 60 cc of condensate, the oil bowl 98 cc, and the whole unit weighs 1020 g.
The filter and regulator share one body, so there is one less inter-unit joint to seal compared to a three-piece train. This model has a 40 um element and a circular gauge reading MPa/psi. With a max supply of 1.0 MPa, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range.

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.

Feed a 1/4in line to a CNC spindle air curtain. The 40 um element traps particulates, while the lubricator meters oil to the spindle bearings, keeping the air film consistent.
Run a small conveyor divert gate. The 0.15-0.9 MPa range covers typical cylinder pressures, and the 98 cc oil bowl keeps the actuator lubricated across a full shift.
Power a pneumatic screwdriver on a bench. The metal bowl resists accidental knocks, and the semi-auto drain clears water when the station cycles off.
This GAFC300 uses a 1/4in port, sitting between the smaller GAFC200 (1/8in ports, 590 g) and the larger GAFC400 (3/8in ports, 1810 g). The metal bowl is a build choice for the assembly line; the catalogue lists no impact or chemical data, so confirm it suits your environment. The semi-auto drain dumps condensate when pressure drops, while the manual drain works on demand. The 40 um element handles standard shop air; choose the W code for 5 um filtration if you feed precision valves. The PT thread comes with a gauge scaled in MPa/psi. Spare parts are orderable as GAFR300-08 and GAL300-08. Since the lubricator adds oil mist last, select a plain GAFR if your line must stay oil-free. The 60 cc drain bowl holds about 2.4x the condensate of the GAFC200's 25 cc bowl, meaning fewer service visits.
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.
It operates at 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). The temperature range is -5 to 70 C. It has a 60 cc drain bowl and 98 cc oil bowl, weighs 1020 g, and uses ISO VG 32 lubricant.
The C code specifies a metal bowl, a build choice for the assembly line. The catalogue gives no temperature or impact data for either material, so confirm the metal bowl suits your surroundings. The pressure rating is identical to the PC and nylon versions.
