About the Airtac GAFC Air Service Unit GAFC300C08ALK
This GAFC300C08ALK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a shared T-bracket with quick clamps. Air enters the first body where the 40 um element removes moisture and solid particles, and the regulator sets the pressure to a lower 0.15-0.4 MPa (20-58 psi) band. The lubricator then adds a metered oil mist downstream, so oil never travels back through the regulator seat.
The metal bowl (C code) holds 60 cc of condensate, while the separate oil bowl holds 98 cc. At 1020 g, this 1/4in unit suits a panel or frame mount rather than tubing support. The automatic drain clears collected water without an operator, and the fitted circular gauge reads in MPa/psi for the PT thread. A reverse-flow (reflux) valve is included, shown as a separate symbol in the catalogue.

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 GAFC300C08ALK Is Used
Low-pressure assembly jigs
Feed a compact pneumatic press or clamping jig that operates below 0.4 MPa, where the lower-pressure regulator prevents over-pressuring delicate workpieces.
Light conveyor lubrication
Supply a short conveyor's air cylinders with filtered, regulated air and a controlled oil mist, keeping moving parts lubricated without manual attention.
Lab air preparation
Prepare air for a laboratory fixture or test stand that needs clean, regulated air at modest pressure, with the automatic drain reducing maintenance between experiments.
Is the Airtac GAFC Air Service Unit GAFC300C08ALK the Right Air-Prep Unit?
Choose this GAFC300C08ALK when the line needs 1/4in ports and a regulated output capped at 0.4 MPa. The L type suits low-pressure circuits, but if the machine may ever require more than 0.4 MPa, select the standard S type instead. The metal bowl is a build choice; the common specification of 1.0 MPa max and -5 to 70 C applies to all bowl materials, so confirm the metal suits your surroundings. The automatic drain is decisive for unattended operation, and the reverse-flow valve is fitted per the K code. The gauge is supplied and reads MPa/psi for the PT thread. For oil-free air downstream, omit the lubricator and choose a plain GAFR300-08 filter-regulator; otherwise the lubricator needs ISO VG 32 oil. Replacement units are orderable separately as GAFR300-08 and GAL300-08. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFR300-08 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC300C08ALK FAQ
This F.R.L. combination operates at 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). The temperature range is -5 to 70 C. It has a 60 cc drain bowl and a 98 cc oil bowl, weighs 1020 g, and uses ISO VG 32 lubricant. The 40 um element filters the air, and the automatic drain clears condensate.
The L type regulates to a maximum of 0.4 MPa (58 psi), while the standard S type reaches 0.9 MPa (130 psi). This model is capped at 0.4 MPa, so it suits low-pressure circuits only. If your application may need higher pressure, the S type is the correct choice. The lower ceiling means the 1.0 MPa max supply leaves about 0.6 MPa of headroom above the regulated band.
