About the Airtac GAFC Air Service Unit GAFC300C10ASWK
This GAFC300C10ASWK 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 and 1020 g mass place it in the mid-size class, suited for feeding a single machine station or a small bank of actuators without overbuilding the air prep.
Air enters the first body where the 5 um element traps fine particles and the regulator sets pressure from 0.15 to 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 here, and the automatic drain clears condensate without an operator, which suits lines that run unattended between shifts.

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 GAFC300C10ASWK Is Used
CNC spindle air
Feed a 5 um filtered and regulated supply to a CNC spindle air curtain or tool changer, where fine particles would otherwise score precision surfaces.
Assembly station
Power a multi-fixture assembly station with several pneumatic screwdrivers or push cylinders, where the 60 cc condensate bowl and 98 cc oil bowl support a full shift between services.
Test rig actuation
Run a laboratory test rig that cycles a pneumatic cylinder repeatedly, relying on the automatic drain to keep moisture out of the regulator during long automated sequences.
Is the Airtac GAFC Air Service Unit GAFC300C10ASWK the Right Air-Prep Unit?
The GAFC300 body offers 1/4in, 3/8in and 1/2in port options; this 3/8in version sits between the smaller GAFC200 and the larger GAFC400. The metal bowl (C code) is a build choice for the specified environment, and the shared specification of 1.0 MPa max and -5 to 70 C applies regardless of bowl material, so confirm the metal suits your surroundings. The automatic drain (A) removes the need for manual condensate checks, while the 5 um element (W) traps finer particles than the standard 40 um grade, at the cost of more frequent element service. A circular gauge is fitted, reading MPa and psi on the PT thread scale. The reverse-flow (reflux) valve is fitted per the K code, shown as a separate pneumatic symbol in the catalogue. The two units are orderable separately 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 a supply near maximum if you need the full output pressure.
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 GAFC300C10ASWK FAQ
This F.R.L. combination operates from 0.15 to 0.9 MPa (20-130 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, and the recommended lubricant is ISO VG 32. It has a 60 cc drain bowl and a 98 cc oil bowl, and the complete unit weighs 1020 g.
The C code specifies a metal bowl, which is a build choice for the environment where the unit will be installed. The A code specifies an automatic drain, which clears condensate without an operator, making it suitable for lines that run unattended. The catalogue does not publish impact or chemical resistance data for bowl materials, so confirm the metal bowl suits your specific conditions.
