About the Airtac GAFC Air Service Unit GAFC300C10LWK
This AirTAC GAFC300C10LWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T bracket. The 3/8" port size suits a mid-size machine line, and the metal bowl is specified by the C code. It 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 lower-pressure type tops out at 0.4 MPa, so plan for a supply near 1.0 MPa if you need the full band. The 60 cc condensate bowl and 98 cc oil bowl set the service rhythm, and the 1020 g mass means a proper panel or frame mount, not support from the tubing. A circular gauge is fitted, reading MPa and psi on the PT thread scale.

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 GAFC300C10LWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element protects tight internal clearances and the lower pressure range prevents over-actuation.
Assembly station air
Supply a multi-spindle assembly station with cleaned, regulated air at a consistent 0.3 MPa, where the metal bowl suits a shop floor with occasional coolant splash.
Test rig instrumentation
Run a leak-test fixture that needs a stable 0.25 MPa supply and fine filtration, with the 98 cc oil bowl keeping the lubricator filled through a full shift.
Is the Airtac GAFC Air Service Unit GAFC300C10LWK the Right Air-Prep Unit?
Choose the GAFC300C10LWK when your line needs fine filtration at a lower regulated pressure. The metal bowl is a build choice for the surroundings, but the shared specification of 1.0 MPa max and -5 to 70 C does not change with it, so confirm the material suits your environment. The semi-auto drain dumps on each pressure drop and the manual drain works on demand, while the 5 um element requires more frequent service than a 40 um grade. The reverse-flow (reflux) valve is fitted, and the gauge reads in MPa and psi on the PT thread. Order the GAFR300-10 filter-regulator and GAL300-10 lubricator as spares. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
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 GAFC300C10LWK FAQ
The GAFC300C10LWK operates from 0.15 to 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 works from -5 to 70 C and should not freeze. The drain bowl holds 60 cc and the oil bowl 98 cc. Use ISO VG 32 lubricant. The complete unit weighs 1020 g.
The C code specifies a metal bowl for the filter and lubricator. The catalogue gives no separate temperature or impact data for the material, so the shared specification of 1.0 MPa max and -5 to 70 C applies. Confirm the metal suits your environment, especially around solvents or impacts.
