The AirTAC Airtac GAFC Air Service Unit GAFC300N08AS 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).
This GAFC300N08AS is an F.R.L. combination built as two units on one T-shape bracket: a filter-regulator body followed by a lubricator. The 1/4in port size and 1020 g mass place it in the mid-range class, suited for a single machine station or a small production cell. The nylon bowl is specified by the N before the port code, and the 60 cc condensate bowl plus 98 cc oil bowl define the service interval.
The standard pressure type regulates from 0.15 to 0.9 MPa (20-130 psi), with a 40 um element filtering the air before the lubricator adds a metered oil mist downstream. The automatic drain clears condensate without an operator, which suits lines that run unattended between shifts. A circular gauge is fitted, reading in MPa and psi on the default PT thread scale.

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 solenoid-operated coolant valve on a small CNC lathe. The 40 um element protects the valve seat, while the automatic drain keeps condensate out of the pilot air during overnight runs.
Supply a single guide-rail cylinder on a carton erector. The 60 cc bowl handles a full shift of condensate in humid conditions, and the gauge lets the operator verify the 0.4 MPa setpoint for gentle product handling.
Power a pneumatic test fixture that cycles a small actuator. The regulated output stays within the 0.15-0.9 MPa band, and the lubricator meters ISO VG 32 oil to the moving parts without over-oiling the exhaust.
Choose this GAFC300N08AS when you need a 1/4in port with the convenience of an automatic drain and a nylon bowl. The nylon bowl is a build choice, not a performance upgrade - the 1.0 MPa max and -5 to 70 C range are identical across PC, metal and nylon, so confirm the material suits your environment. The standard type covers 0.15-0.9 MPa (20-130 psi); if your process only needs up to 0.4 MPa, the L type would be lighter on the regulator spring, but this S version gives the full range. The 40 um element is the default; step to the W option for 5 um filtration if you feed precision valves. The gauge reads MPa/psi, matching the PT thread. Spare parts are orderable as GAFR300-08 and GAL300-08, so a damaged bowl or clogged element does not scrap the whole assembly. Remember the lubricator adds oil mist last - if your line must stay oil-free, choose a plain GAFR filter-regulator instead. With a 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan inlet pressure near the maximum if you need the full 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
The GAFC300N08AS operates from 0.15 to 0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the unit weighs 1020 g. It has a 60 cc condensate bowl and a 98 cc oil bowl, and the recommended lubricant is ISO VG 32 or equivalent.
The N code specifies a nylon bowl instead of the default polycarbonate. The catalogue lists the same pressure and temperature limits for both materials, so the choice is about your installation environment. Confirm that nylon suits your specific conditions - the data sheet does not provide impact or chemical resistance figures for either material.
