About the Airtac GAFC Air Service Unit GAFC300C10ASK
This GAFC300C10ASK 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. The 3/8in port size and 1020 g mass place it in the mid-range class, suitable for feeding a single machine station or a small bank of actuators.
Air enters the first body where the 40 um element removes solids and moisture, and the regulator sets pressure within 0.15-0.9 MPa (20-130 psi). The lubricator then adds a metered oil mist downstream, so oil never travels back through the regulator seat. The metal bowl is specified by the C code, and the automatic drain clears condensate without operator intervention.

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 GAFC300C10ASK Is Used
CNC coolant valve control
Feed a 3/8in line to a solenoid manifold controlling coolant jets on a small CNC mill, where the automatic drain keeps the bowl clear during long unattended runs.
Assembly station air prep
Supply a bench-top assembly station with filtered, regulated air for pneumatic screwdrivers and push-in fittings, with the metal bowl resisting accidental knocks from tools.
Packaging line actuator bank
Power a series of 3/8in ported cylinders on a carton-erecting machine, using the 0.15-0.9 MPa range to set consistent force for film wrapping and sealing heads.
Is the Airtac GAFC Air Service Unit GAFC300C10ASK the Right Air-Prep Unit?
The GAFC300 body offers 1/4in, 3/8in and 1/2in port options; this 3/8in version balances flow capacity against fitting size for typical shop air lines. The metal bowl is a build choice for environments where the buyer prefers non-transparent construction, though the catalogue lists identical pressure and temperature limits for all bowl materials, so confirm compatibility for your specific surroundings. The automatic drain suits unattended operation, and the fitted circular gauge reads in MPa and psi for the default PT thread. The reverse-flow (reflux) valve is included per the K code. Spare parts are orderable as GAFR300-10 and GAL300-10. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan inlet pressure accordingly if you need the full output.
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 GAFC300C10ASK FAQ
This F.R.L. combination operates on air from 0.15-0.9 MPa (20-130 psi), with a maximum 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 filter element and automatic drain are standard for this code.
The K code specifies that a reverse-flow (reflux) valve is fitted to the assembly. The catalogue shows this as a separate pneumatic symbol in the circuit diagram. It is an ordering difference from the base model, and its detailed function is covered on a separate page in the catalogue.
