About the Airtac GAFC Air Service Unit GAFC400C15SNWK
This AirTAC GAFC400C15SNWK 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 1/2in port and 1810 g mass place it in the mid-size class, suited for machine headers feeding several actuators. It filters to 5 um, regulates from 0.15-0.9 MPa (20-130 psi), and the metal bowl is specified by the C code.
The filter and regulator share one housing, so the assembly has one less inter-unit joint than a three-piece filter-regulator-lubricator train. Air is cleaned and set to pressure first, then the lubricator adds a metered oil mist downstream. The 100 cc condensate bowl and 185 cc oil bowl define the service interval, and the 5 um element traps finer particles for sensitive valves, though it will need more frequent attention than a 40 um element.

Where the Airtac GAFC Air Service Unit GAFC400C15SNWK Is Used
Precision valve circuits
The 5 um element protects sensitive pneumatic valves and instrument air from fine particles, making this unit suitable for precision machining centers or assembly stations where consistent actuation matters.
Machine headers
With a 1/2in port and 6000 L/min flow envelope at 0.7 MPa inlet, this unit feeds a machine header serving multiple cylinders or a small production line, providing regulated and lubricated air to each branch.
Test benches
The 0.15-0.9 MPa (20-130 psi) range and metal bowl suit test benches that cycle frequently, where the semi-auto drain clears condensate on each pressure drop and the 5 um element keeps test fixtures clean.
Is the Airtac GAFC Air Service Unit GAFC400C15SNWK the Right Air-Prep Unit?
Choose this GAFC400C15SNWK when a 1/2in port and 1810 g mass fit your panel layout. The metal bowl is a build choice, not a performance upgrade - the 1.0 MPa (145 psi) maximum and -5 to 70 C range apply to all bowl materials, so confirm the metal suits your environment. The semi-auto drain dumps condensate on each pressure drop, with a manual drain for on-demand use, and the 5 um element suits precision valve circuits. No gauge is supplied, so the 1/4in gauge connection must be fitted if you need to read the set pressure. The reverse-flow (reflux) valve is fitted, and the PT thread carries a MPa/psi scale. The lubricator is meant to carry ISO VG 32 oil, so if the line must stay oil-free, choose a plain GAFR400-15 filter-regulator instead; the GAL400-15 lubricator is separately orderable. With 1.0 MPa max supply, you have about 0.1 MPa above the 0.9 MPa top of the regulated band, so plan a supply near 1.0 MPa if you need 0.9 MPa out.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 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 GAFR400-15 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C15SNWK FAQ
The GAFC400C15SNWK operates 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). Temperature range is -5 to 70 C. It has a 100 cc condensate bowl and 185 cc oil bowl, weighs 1810 g, and uses ISO VG 32 lubricant. The element is 5 um and the port is 1/2in.
The N in the code after the port means no gauge is supplied with this unit. The GAFC400 body has a 1/4in gauge connection, so you can add a gauge later if you need to read the set pressure. The PT thread determines that a gauge fitted here would read in MPa and psi.
