About the Airtac GAFC Air Service Unit GAFC400N15L
This AirTAC GAFC400N15L 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 or multi-station lines where a smaller unit would struggle.
Air is cleaned and set to pressure in the first body, then the lubricator meters oil mist into the flow last, so oil never travels back through the regulator seat. The lower-pressure type regulates from 0.15 to 0.4 MPa (20-58 psi), with a 40 um element and a circular gauge reading MPa/psi for the PT thread.

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 GAFC400N15L Is Used
Precision Fixture Clamping
Feed a multi-station clamping fixture on a CNC machining center. The 1/2in port and lower 0.4 MPa range suit delicate workholding where higher pressure could distort parts.
Assembly Line Pneumatics
Supply a bank of air tools or actuators on an assembly line. The 100 cc condensate bowl and 185 cc oil bowl reduce how often an operator must check levels during a shift.
Packaging Machine Air Prep
Protect a packaging machine's valves and cylinders. The nylon bowl is a material choice, and the semi-auto drain clears water on each pressure drop to keep the line dry.
Is the Airtac GAFC Air Service Unit GAFC400N15L the Right Air-Prep Unit?
Choose the GAFC400N15L when your line needs a 1/2in port and a lower regulated ceiling of 0.4 MPa. The nylon bowl is a build choice; the shared specification of 1.0 MPa max and -5 to 70 C applies, so confirm the material suits your surroundings. This unit ships with both semi-auto and manual drains, letting condensate dump on pressure drop or on demand. The 40 um element handles general shop air; step to the 5 um version if you need finer filtration. The circular gauge is fitted and reads MPa/psi. For oil-free lines, omit the lubricator and choose a plain GAFR400-15 filter-regulator instead. Spares are orderable as GAFR400-15 and GAL400-15. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan your inlet pressure accordingly.
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 GAFC400N15L FAQ
This lower-pressure unit regulates air from 0.15 to 0.4 MPa (20-58 psi). Maximum supply pressure is 1.0 MPa (145 psi), with a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 100 cc and the oil bowl 185 cc. Recommended lubricant is ISO VG 32. The complete assembly weighs 1810 g.
The L indicates the lower-pressure type, regulating from 0.15 to 0.4 MPa instead of the standard 0.15 to 0.9 MPa. This is suitable for applications needing a gentle, consistent pressure. If your machine may ever require more than 0.4 MPa, the standard S type is the correct choice.
