About the Airtac GAFC Air Service Unit GAFC300C10LNWK
This AirTAC GAFC300C10LNWK is an F.R.L. combination built as two units on one T-shape bracket: a filter-regulator body followed by a lubricator. The 3/8in port size and 1020 g mass place it in the mid-range class, suitable for feeding a small machine station or a bank of actuators. It carries a metal bowl, a 5 um element, and a reverse-flow valve, with a lower-pressure regulation band of 0.15-0.4 MPa (20-58 psi).
The filter and regulator share one body, so there is one less inter-unit joint to seal compared with a three-piece filter-regulator-lubricator train. Air is cleaned and set to pressure first, then the lubricator adds a metered oil mist last, so oil never passes back through the regulator seat. The 60 cc condensate bowl and 98 cc oil bowl define the service interval, and the 1/8in gauge connection is ready if a gauge is added later.

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 GAFC300C10LNWK Is Used
Precision valve protection
The 5 um element filters fine particles before air reaches sensitive solenoid valves on a small assembly fixture, while the lower-pressure range keeps the actuation gentle.
Low-pressure packaging line
A carton-sealing station using small cylinders benefits from the 0.15-0.4 MPa band, providing consistent force without over-pressurizing lightweight mechanisms.
Bench test rig
On a pneumatic test bench for checking valve response, the metal bowl and 5 um element deliver clean, regulated air at controlled low pressure, with the reverse-flow valve fitted as specified.
Is the Airtac GAFC Air Service Unit GAFC300C10LNWK the Right Air-Prep Unit?
The GAFC300 body with a 3/8in port suits moderate flow demands, with the catalogue flow curve plotted to 3500 L/min at 0.7 MPa inlet. The metal bowl is a build choice for the specified surroundings; the shared specification of 1.0 MPa maximum and -5 to 70 C applies regardless, so confirm the material fits your environment. The 5 um element traps finer particles than the standard 40 um, which protects precision valves but requires more frequent element service. The semi-auto drain dumps condensate on each pressure drop, while the manual drain gives on-demand control. No gauge is supplied, so the set pressure cannot be read without adding one to the 1/8in connection. The reverse-flow valve is fitted, and the PT thread carries a gauge scale of MPa/psi if a gauge is installed. Replacement units are orderable separately as GAFR300-10 and GAL300-10. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan the inlet pressure with that margin in mind.
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 GAFC300C10LNWK FAQ
The GAFC300C10LNWK operates at 0.15-0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It has a 60 cc condensate bowl and a 98 cc oil bowl, weighs 1020 g, and is rated for -5 to 70 C. The recommended lubricant is ISO VG 32, and the unit uses a 5 um filter element.
The C in the code specifies a metal bowl, which is a build choice for the intended surroundings; the catalogue gives no material-specific performance data, so confirm compatibility for your environment. The N after the port code means no gauge is supplied, so the 1/8in gauge connection is left open for a gauge you add later. The reverse-flow valve is fitted as indicated by the K.
