About the Airtac GAFC Air Service Unit GAFC300C10ASNWK
This GAFC300C10ASNWK is a two-piece F.R.L. combination: a filter-regulator body that cleans the air and sets its pressure, joined on a T-bracket to a lubricator that adds a metered oil mist downstream. With a 3/8in port and a 5 um element, it suits precision pneumatic circuits where fine filtration matters. The metal bowl (C code) is a build choice for the installation environment, and the automatic drain clears condensate without an operator.
The standard pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum. This unit weighs 1020 g and carries a 60 cc condensate bowl plus a 98 cc oil bowl, so service intervals are practical for a mid-size machine. No gauge is supplied with this model, but the 1/8in gauge connection is ready for one if you need to read the set pressure directly.

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 GAFC300C10ASNWK Is Used
Precision valve actuation
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element protects fine internal clearances from abrasive particles, and the automatic drain keeps the supply dry without daily attention.
Machine tool lubrication
Supply a controlled oil mist to a multi-spindle drilling head on a CNC machine, where the 98 cc oil bowl supports extended runs and the metal bowl suits a shop floor with coolant splash.
Test rig air preparation
Prepare air for a laboratory test fixture that cycles a cylinder at set pressures, using the 0.15-0.9 MPa range to dial in exact actuation forces while the 5 um element keeps the test media clean.
Is the Airtac GAFC Air Service Unit GAFC300C10ASNWK the Right Air-Prep Unit?
Select this GAFC300C10ASNWK when you need a 3/8in F.R.L. set with a 5 um element and automatic drain for a line that runs unattended. The metal bowl is specified by the C code, and the shared specification (1.0 MPa max, -5 to 70 C) applies to all bowl materials, so confirm the metal suits your surroundings. The K code means a reverse-flow (reflux) valve is fitted, and the PT thread carries a gauge scale in MPa/psi if you add a gauge later. For a smaller footprint, the GAFC200 offers 1/4in ports with a 25 cc drain bowl; for more capacity, the GAFC400 steps up to 3/8in and 1/2in ports with a 100 cc drain bowl. The two units are orderable separately as the GAFR300-10 filter & regulator and the GAL300-10 lubricator. Since the lubricator adds oil mist, choose a plain GAFR if your line must stay oil-free. The 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the regulated range, so plan your inlet pressure accordingly.
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 GAFC300C10ASNWK FAQ
This F.R.L. combination operates on air with a standard pressure range of 0.15-0.9 MPa (20-130 psi), a maximum pressure of 1.0 MPa (145 psi), and a 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, weighs 1020 g, and uses a 5 um filtering element.
The C code specifies a metal bowl, which is a build choice for the installation environment; the catalogue does not provide impact or chemical data for bowl materials, so confirm it suits your surroundings. The N after the port code means no gauge is supplied, but the 1/8in gauge connection is present if you want to add one. The K code adds a reverse-flow (reflux) valve, which is fitted as a standard option on this unit.
