The AirTAC Airtac GAFC Air Service Unit GAFC300C10S 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 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).
This GAFC300C10S is a two-piece F.R.L. combination: a filter and regulator share one body, and a lubricator is mounted beside it on a T-bracket with quick clamps. The 3/8in port and 1020 g mass place it in the mid-size class, suited for a single machine station or a short distribution line.
Air enters the first body where solids and moisture are removed and pressure is set to 0.15-0.9 MPa (20-130 psi). The lubricator then adds a controlled oil mist downstream, so oil never travels back through the regulator seat. The 40 um element handles standard shop air, and the metal bowl is specified by the C code.

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 3/8in line to a CNC spindle air-oil lubrication unit, where the regulated 0.15-0.9 MPa range and metered oil mist keep bearings running without over-oiling.
Mount on a workbench feeding pneumatic screwdrivers or push-in fittings, using the 60 cc condensate bowl to catch moisture from a humid compressor line before it reaches tools.
Supply a 3/8in test fixture that needs a stable 0.4 MPa setpoint, with the metal bowl protecting against accidental impacts in a busy lab environment.
Choose the GAFC300 body when your line needs 3/8in ports and a 60 cc condensate bowl with a 98 cc oil bowl. The metal bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C rating are identical across PC, metal and nylon, so confirm the material suits your environment. This model ships with both semi-auto and manual drains: the semi-auto dumps when pressure drops, the manual works on demand. The circular gauge is fitted and reads in MPa and psi for the PT thread. For cleaner air, select the W option for a 5 um element, though it will need service more often. Spares are orderable as GAFR300-10 and GAL300-10. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa top of the regulated range, so plan your inlet pressure accordingly.
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.
The GAFC300C10S operates from 0.15 to 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). Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32. The complete unit weighs 1020 g.
The C in the code specifies a metal bowl for the filter and lubricator. The catalogue does not publish impact, chemical or temperature data for bowl materials - the common specification of 1.0 MPa max and -5 to 70 C applies to all options. Choose metal if your environment demands it, but confirm compatibility with your specific conditions.
