About the Airtac GAFC Air Service Unit GAFC300C10ALNW
This GAFC300C10ALNW is a two-piece F.R.L. combination: a filter and regulator share one body, and a lubricator is joined on a T-bracket. The 3/8in port, 1020 g unit preps air for a single machine or a small line, with a 5 um element trapping fine particles before the pressure is set.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 1.0 MPa (145 psi) maximum supply. The metal bowl and automatic drain handle condensate without an operator, while the 60 cc drain bowl and 98 cc oil bowl define the service interval. A gauge is not fitted; the 1/8in gauge connection is ready for one if needed.

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 GAFC300C10ALNW Is Used
Precision valve control
The 5 um element and lower-pressure range suit a precision pneumatic valve on a small assembly fixture, where fine filtration and a 0.4 MPa ceiling protect sensitive components.
Small machine lubrication
Feed a single-station drilling or tapping machine with filtered, regulated air and a metered oil mist, keeping the tool cylinder lubricated without over-oiling the line.
Test bench air prep
On a lab test bench, the automatic drain and metal bowl handle condensate from a wet compressor line, while the 5 um element protects test gauges and orifices from fine debris.
Is the Airtac GAFC Air Service Unit GAFC300C10ALNW the Right Air-Prep Unit?
Choose the GAFC300 body for medium flows, with the 3/8in port feeding actuators or small headers. The metal bowl is a build choice; the catalogue gives no impact or chemical data, so confirm it suits your surroundings. The automatic drain clears condensate without an operator, ideal for wet or unattended lines. The 5 um element suits precision valves but needs more frequent service than the 40 um standard. The L type tops out at 0.4 MPa, so if the machine may need more pressure, select the S type instead. The PT thread and no-gauge spec mean adding a gauge later requires the 1/8in connection. Spares are the GAFR300-10 filter-regulator and the GAL300-10 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure carefully for full regulation.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFR300-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300C10ALNW FAQ
The working pressure range is 0.15-0.4 MPa (20-58 psi), with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and uses ISO VG 32 lubricant. The drain bowl holds 60 cc and the oil bowl 98 cc, with a total weight of 1020 g.
The N in the code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so you can add a circular gauge later if you need to read the set pressure. The thread is PT, and a gauge added would read in MPa and psi.
