About the Airtac GAFC Air Service Unit GAFC400C10LNWK
This GAFC400C10LNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator, mounted on a T-bracket with quick clamps. It handles a 3/8in port and weighs 1810 g, placing it in the mid-size class for multi-actuator circuits. The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 5 um element for finer filtration.
The metal bowl holds 100 cc for condensate and 185 cc for oil, so service intervals are generous for a unit this size. No gauge is supplied, but the 1/4in gauge connection allows one to be added. A reverse-flow valve is fitted, and the lubricator adds oil mist after the air is filtered and set to pressure.

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 GAFC400C10LNWK Is Used
Precision valve islands
Feed a bank of solenoid valves on a pick-and-place machine where 5 um filtration protects tight spool clearances and the 0.4 MPa ceiling suits low-force grippers.
Assembly line workstations
Supply a multi-station assembly bench with regulated air for screwdrivers and presses, where the 185 cc oil bowl keeps lubricators topped up across shifts.
Test rigs and lab equipment
Run a pneumatic test fixture that needs clean, oil-misted air at a stable low pressure, with the metal bowl standing up to frequent handling.
Is the Airtac GAFC Air Service Unit GAFC400C10LNWK the Right Air-Prep Unit?
Choose this GAFC400C10LNWK when your line needs finer 5 um filtration and a lower pressure ceiling of 0.4 MPa. The metal bowl is a build choice; the catalogue lists no performance difference versus PC or nylon, so confirm it suits your environment. The semi-auto drain dumps condensate when pressure drops, while the manual drain works on demand. No gauge is included, so plan to read pressure elsewhere or add one to the 1/4in connection. The reverse-flow valve is fitted per the K code. Spares are the GAFR400-10 filter-regulator and GAL400-10 lubricator, both orderable separately. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.
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 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 GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C10LNWK FAQ
It operates from 0.15 to 0.4 MPa (20-58 psi) with a max 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 drain bowl and 185 cc oil bowl, weighs 1810 g, and uses ISO VG 32 lubricant. The element is 5 um.
The N in the code means no gauge is supplied. The GAFC400 body has a 1/4in gauge connection, so you can add a circular gauge later if you need to read the set pressure directly. The thread is PT with a MPa/psi scale if you fit one.
