About the Airtac GAFC Air Service Unit GAFC400C10L
This GAFC400C10L is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. Air is cleaned and set to pressure in the first body, then the lubricator adds a controlled oil mist downstream, so oil never travels back through the regulator seat. With a 3/8in port and a 1810 g mass, it suits mid-size machine headers or multi-actuator stations where a compact footprint still matters.
The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), a deliberately narrow band for gentle or sensitive circuits. The metal bowl is specified by the C code, and the common specification of 1.0 MPa max and -5 to 70 C applies regardless of bowl material. A circular gauge is fitted, reading MPa/psi for the default PT thread, and the 40 um element handles standard shop air.

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 GAFC400C10L Is Used
Precision Assembly Stations
Feed a delicate press-fit or insertion station where the 0.15-0.4 MPa band prevents over-force on small parts. The metal bowl suits a production area where operators handle the unit regularly.
Mid-Size Machine Headers
Supply a multi-valve manifold on a packaging or assembly machine with a 3/8in header. The 100 cc condensate bowl and 185 cc oil bowl reduce how often maintenance visits the unit.
Test and Calibration Rigs
Run a low-pressure test fixture that needs a stable 0.2-0.35 MPa supply. The lower-pressure regulator holds the set point as line pressure varies, and the gauge lets an operator verify it.
Is the Airtac GAFC Air Service Unit GAFC400C10L the Right Air-Prep Unit?
Choose the GAFC400 body for a 3/8in port with a 100 cc condensate bowl and a 185 cc oil bowl, giving a longer service interval than the GAFC300's 60 cc and 98 cc bowls. The metal bowl is a build choice; confirm it suits your surroundings, as the catalogue lists no material-specific ratings. This L-type model tops out at 0.4 MPa, so if the machine may ever need more pressure, select the S type instead. The semi-auto drain dumps condensate on each pressure drop, with a manual drain for on-demand use, and the PT thread carries an MPa/psi gauge scale. Spare parts are orderable as GAFR400-10 and GAL400-10. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated 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 GAFC400C10L FAQ
The GAFC400C10L is a lower-pressure F.R.L. combination operating from 0.15 to 0.4 MPa (20-58 psi). Maximum supply pressure is 1.0 MPa (145 psi) and proof pressure is 1.5 MPa (215 psi). It works in -5 to 70 C temperatures and uses ISO VG 32 lubricant. The unit has a 100 cc condensate bowl, a 185 cc oil bowl, and weighs 1810 g.
The C code specifies a metal bowl, which is a build choice for the unit's surroundings; the catalogue gives no material-specific ratings, so confirm it fits your environment. The L code sets the lower 0.15-0.4 MPa range, suitable for circuits that must not exceed 0.4 MPa. If your machine may need more pressure, choose the S type instead.
