About the Airtac GAFC Air Service Unit GAFC300N15LNW
This GAFC300 F.R.L. combination pairs a filter-regulator with a lubricator on a single T-bracket, so the air is cleaned and set to pressure in the first body, then the lubricator adds a controlled oil mist last. With a 1/2in port and a 1020 g mass, it suits medium-duty lines where a smaller unit would struggle to feed multiple actuators.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), and the 5 um element traps finer particles than the standard 40 um grade. The nylon bowl holds 60 cc of condensate and the oil bowl holds 98 cc, so the service interval is set by how wet the line is. No gauge is supplied; the 1/8in gauge connection is there if you add one later.

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 GAFC300N15LNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element protects fine internal passages from particle wear.
Medium conveyor drives
Supply a 1/2in header that runs several conveyor belt actuators, where the 98 cc oil bowl keeps lubricant flowing between shifts.
Test bench air supply
Set up a lab test bench needing regulated air at 0.3 MPa for cylinder cycling, with the lower-pressure range giving finer adjustment at that level.
Is the Airtac GAFC Air Service Unit GAFC300N15LNW the Right Air-Prep Unit?
Choose the GAFC300 body for a 1/2in port with a 3500 L/min flow envelope at 0.7 MPa inlet, which is double the GAFC200's 1750 L/min curve. The nylon bowl is a build choice, but the shared specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm it suits your surroundings. The semi-auto drain dumps condensate on each pressure drop, and the manual drain is there for on-demand use; the 5 um element needs more frequent service than the 40 um standard, so weigh that against the finer filtration.
The L type tops out at 0.4 MPa, so if your machine may ever need more pressure, this is the wrong part. The PT thread comes with an MPa/psi gauge scale, but since no gauge is fitted, you would need to add one to read the set pressure. Spares are orderable as GAFR300-15 and GAL300-15. Max supply of 1.0 MPa leaves about 0.6 MPa above the 0.4 MPa top of the range, so the regulator has plenty of inlet headroom to hold its setpoint.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAFR300-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300N15LNW FAQ
The working pressure range is 0.15-0.4 MPa (20-58 psi), with a max pressure 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, the oil bowl holds 98 cc, and the unit weighs 1020 g.
The N after the port code means no gauge is supplied. The GAFC300 body has a 1/8in gauge connection, so you can add a gauge later if you need to read the set pressure directly. The PT thread option would normally come with an MPa/psi scale gauge, but this version omits it to reduce cost.
