About the Airtac GAFC Air Service Unit GAFC30015LW
This GAFC30015LW is a two-piece F.R.L. combination: the filter and pressure regulator share one body, and the lubricator mounts on the same T-bracket. Air is cleaned and set to pressure first, then a metered oil mist is added downstream, so oil never crosses the regulator seat. With a 1/2in port and 1020 g mass, it suits a mid-size machine header or a small multi-station line.
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 60 cc drain bowl and 98 cc oil bowl set the service rhythm, and the circular gauge reads in MPa/psi. Max supply is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the unit is rated for -5 to 70 C with ISO VG 32 lubricant.

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 GAFC30015LW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging machine where the 5 um element protects fine internal passages and the 0.4 MPa ceiling matches the valve's operating spec.
Mid-size machine header
Supply a 1/2in header on a small assembly station, where the 60 cc drain bowl and 98 cc oil bowl keep maintenance intervals practical for a two-shift operation.
Instrument air branch
Protect a sensitive instrument loop that needs filtered, regulated, lubricated air at a fixed low pressure, with the 5 um element removing finer particles before the regulator.
Is the Airtac GAFC Air Service Unit GAFC30015LW the Right Air-Prep Unit?
Choose this GAFC30015LW when your circuit needs a 1/2in port and a regulated output capped at 0.4 MPa. The L type tops out at 0.4 MPa, so if the machine may ever require more pressure, step to the standard S type instead. The semi-auto drain dumps condensate on each pressure drop, with a manual drain for on-demand use; the PC bowl is the standard build, and the 5 um element suits precision valves or instrument air at the cost of more frequent element service. The circular gauge is fitted with an MPa/psi scale for the PT thread. The filter-regulator and lubricator are orderable separately as GAFR300-15 and GAL300-15. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the range, so plan the supply pressure accordingly.
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 GAFC30015LW FAQ
The GAFC30015LW is a lower-pressure F.R.L. combination with a working range of 0.15-0.4 MPa (20-58 psi). Max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. The drain bowl holds 60 cc, the oil bowl holds 98 cc, and the unit weighs 1020 g. Recommended lubricant is ISO VG 32. The element grade is 5 um, and the circular gauge reads in MPa/psi.
The W code specifies a 5 um element, which traps far finer particles than the standard 40 um grade. This is a deliberate choice for circuits with precision valves, small orifices, or instrument air where finer filtration reduces wear and sticking. The trade-off is that the 5 um element will load with contaminant faster, so it needs more frequent inspection and replacement than a 40 um element would.
