About the Airtac GAFC Air Service Unit GAFC300N08ALN
This AirTAC GAFC300N08ALN is a two-piece F.R.L. combination: the filter and regulator share one body, and the lubricator is a separate unit on the same bracket. Air is cleaned and set to pressure in the first body, then the lubricator adds a controlled oil mist last, so the oil never travels back through the regulator seat. The 1/4in port and 1020 g mass place it in the mid-size class, a step above the 590 g GAFC200 for lines that need more condensate and oil capacity.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), which suits machines with a fixed, modest pressure demand. The 60 cc condensate bowl and 98 cc oil bowl on this model mean fewer visits to drain and refill than the 25 cc and 36 cc bowls of the smaller GAFC200. A 40 um element is fitted as standard, and the nylon bowl is named as a build choice, though the catalogue gives no impact or chemical data, so confirm it suits your surroundings.

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.

Where the Airtac GAFC Air Service Unit GAFC300N08ALN Is Used
Precision Assembly Fixtures
Feed a single-axis pressing fixture or a small indexing table that needs a steady 0.3 MPa supply. The lower-pressure range gives fine control for delicate part placement without over-stroking a cylinder.
Laboratory Air Supply
Supply a lab bench with a filtered and regulated air source for pneumatic actuators on test rigs. The automatic drain keeps condensate out of sensitive instruments, and the 40 um element protects small orifices.
Low-Pressure Packaging Line
Run a film-sealing or carton-erecting station where the air demand is low and consistent. The 60 cc condensate bowl and 98 cc oil bowl reduce maintenance stops compared to a smaller unit.
Is the Airtac GAFC Air Service Unit GAFC300N08ALN the Right Air-Prep Unit?
The GAFC300 body with a 1/4in port (code 08) offers a good balance of capacity and footprint, with the catalogue flow curve plotted to 3500 L/min at 0.7 MPa inlet for sizing against a real duty point. The nylon bowl is specified by the N before the port, and the automatic drain (A) clears condensate without an operator, which is useful for wet or unattended lines. This model has no gauge fitted, so the set pressure cannot be read without adding one to the 1/8in gauge connection. The lower-pressure type (L) tops out at 0.4 MPa, so if the machine may ever need more than that, this is the wrong part and a standard type is required. The 40 um element is the default, and the thread is PT with a gauge scale of MPa/psi if a gauge is added. The two units are orderable separately as GAFR300-08 and GAL300-08, so a damaged bowl or clogged element does not mean replacing the whole assembly. If the line must stay oil-free, leave the lubricator out and choose a plain GAFR filter-regulator instead. Max supply of 1.0 MPa leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the supply pressure with that margin in mind.
Quick checklist
- ✓ Body size for your peak flow (1/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter-regulator first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1020 g unit on its bracket, not on the tubing.
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.
Airtac GAFC Air Service Unit GAFC300N08ALN FAQ
The working pressure range is 0.15-0.4 MPa (20-58 psi), with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The condensate bowl holds 60 cc and the oil bowl holds 98 cc. Recommended lubricant is ISO VG 32 or equivalent, and the unit weighs 1020 g.
The N after the port code means no gauge is supplied with this unit. The gauge connection on the GAFC300 body is 1/8in, so you can add a gauge later if you need to read the set pressure. The thread is PT, and the gauge scale would read in MPa and psi if one is fitted.
