About the Airtac GAFC Air Service Unit GAFC400C10LN
This AirTAC GAFC400C10LN 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. Air is cleaned and set to pressure in the first body, then the lubricator adds a metered oil mist downstream, so oil never travels back through the regulator seat.
The 3/8in port and 1810 g mass place it in the mid-size class, suited for a machine header feeding several actuators. It works in the lower-pressure band of 0.15-0.4 MPa (20-58 psi) with a 40 um element, and the metal bowl holds 100 cc of condensate while the oil bowl holds 185 cc. No gauge is fitted, so the set pressure cannot be read without adding one to the 1/4in gauge connection.

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 GAFC400C10LN Is Used
Precision pressure setting
Set a lathe's air chuck to a stable 0.3 MPa (43 psi) with the lower-pressure regulator, protecting delicate workpieces from over-clamping while the lubricator keeps the chuck cylinder moving smoothly.
Light conveyor lubrication
Feed a 3/8in line to a small conveyor's guide rails and sensors, using the 185 cc oil bowl to keep the mechanism misted for long shifts without frequent topping up.
Test bench air supply
Power a pneumatic test fixture that cycles at low pressure, relying on the 100 cc condensate bowl to collect moisture from a wet compressor line before it reaches the regulator seat.
Is the Airtac GAFC Air Service Unit GAFC400C10LN the Right Air-Prep Unit?
Choose the GAFC400C10LN when your line needs a 3/8in port and a regulated ceiling of 0.4 MPa (20-58 psi). The metal bowl is a build choice for the environment, but the catalogue gives no impact or chemical data, so confirm it suits your surroundings. The semi-auto drain dumps condensate each time pressure drops, with a manual drain for on-demand use, and the 40 um element handles standard shop air. For finer filtration, the W option swaps to a 5 um element at the cost of more frequent service. The N code means no gauge is supplied; the 1/4in connection accepts one later, and the PT thread carries an MPa/psi scale if you add it. Spares are orderable as the GAFR400-10 filter & regulator and the GAL400-10 lubricator, so a damaged bowl does not force a whole new assembly. A 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 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 GAFC400C10LN FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It handles temperatures from -5 to 70 C and needs ISO VG 32 oil in the lubricator. The metal drain bowl holds 100 cc, the oil bowl holds 185 cc, and the complete unit weighs 1810 g with a 3/8in port.
The N in the code after the port means no gauge is supplied, which keeps the unit compact and reduces cost if you monitor pressure elsewhere. If you need to read the set pressure locally, the GAFC400 body has a 1/4in gauge connection where a standard gauge can be added later, reading in MPa and psi for the PT thread.
