About the Airtac GAFC Air Service Unit GAFC300C15LW
This GAFC300C15LW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 1/2in port and 1020 g mass place it in the mid-range class, suitable for feeding a single machine station or a small bank of cylinders. The metal bowl is specified by the C code, and the unit carries both a 60 cc condensate bowl and a 98 cc oil bowl.
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. A circular gauge is fitted, reading in MPa and psi for the PT thread. Air is filtered and set to pressure in the first body, then the lubricator adds a metered oil mist last, so oil never travels back through the regulator seat.

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 GAFC300C15LW Is Used
Precision Fixture Clamping
Feed a single-station clamping fixture on a CNC machine, where the 5 um element protects fine pneumatic valves and the lower pressure range suits delicate workholding.
Light Assembly Line
Supply a small bank of air cylinders on a light assembly line, with the 60 cc condensate bowl handling moisture from a modest compressor run.
Lab Instrument Air
Power a lab-scale pneumatic actuator or test rig, where the 0.4 MPa ceiling and fine filtration keep instrument air clean and at a controlled low pressure.
Is the Airtac GAFC Air Service Unit GAFC300C15LW the Right Air-Prep Unit?
Choose this GAFC300C15LW when your line needs fine 5 um filtration and a lower 0.4 MPa ceiling, and the metal bowl suits your environment. The semi-auto drain dumps condensate on each pressure drop, while the manual drain gives on-demand control. The PT thread carries a gauge scaled in MPa and psi, matching the default catalogue option. If a reverse-flow valve is required, the K option adds it, but it is not fitted here. Spare parts are the GAFR300-15 filter-regulator and the GAL300-15 lubricator, both orderable separately.
Since the lubricator is meant to carry oil, this set is not for oil-free air lines; select a plain GAFR if no oil mist is allowed. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, giving a comfortable margin for supply fluctuations while staying within the rated band.
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 GAFC300C15LW FAQ
The GAFC300C15LW 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 in -5 to 70 C temperatures and needs ISO VG 32 lubricant. The drain bowl holds 60 cc, the oil bowl 98 cc, and the unit weighs 1020 g with a 1/2in port.
The C code specifies a metal bowl, which is a build choice for the environment. The catalogue gives the same 1.0 MPa max and -5 to 70 C rating for all bowl materials, so confirm the metal suits your surroundings rather than assuming it is tougher. The bowl holds 60 cc of condensate.
