About the Airtac GAFC Air Service Unit GAFC400C15L
This AirTAC GAFC400C15L is a two-piece F.R.L. combination built around a 1/2in port body. The filter and regulator share one housing, so the set delivers filtered, pressure-controlled air before the lubricator adds a metered oil mist downstream. It weighs 1810 g and carries a 100 cc condensate bowl plus a 185 cc oil bowl.
The lower-pressure L type regulates from 0.15 to 0.4 MPa (20-58 psi), which suits machines that never need more than 58 psi. A circular gauge is fitted and reads in MPa and psi. The 40 um element handles standard shop air, while the metal bowls are a build choice for the buyer to confirm against their environment.

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 GAFC400C15L Is Used
Precision pressure control
Set a precise 0.3 MPa (43 psi) for a delicate clamping fixture on a CNC machine, where the lower range gives finer adjustment than a standard regulator.
Paint spray equipment
Feed a spray gun at a consistent 0.35 MPa (51 psi) for even coating, with the lubricator adding a fine oil mist to the air tool.
Assembly line tooling
Power a pneumatic screwdriver on an assembly bench, where the 1/2in port supports the tool's air demand and the 185 cc oil bowl keeps it lubricated.
Is the Airtac GAFC Air Service Unit GAFC400C15L the Right Air-Prep Unit?
Choose the GAFC400C15L when a 1/2in port and a lower pressure ceiling are the right fit. The metal bowl (C) is specified here, and the semi-auto drain dumps condensate on each pressure drop while the manual drain gives on-demand control. The 40 um element is the standard grade; the W option upgrades to 5 um for finer filtration. PT threads come with an MPa/psi gauge scale, and the K option adds a reverse-flow valve if needed. If the line must stay oil-free, omit the lubricator and select a plain GAFR filter-regulator instead. Spare parts are orderable as GAFR400-15 and GAL400-15.
With a 1.0 MPa max supply, this unit leaves about 0.6 MPa above the 0.4 MPa top of its regulated range, so plan the inlet pressure well above the setpoint you need.
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 GAFC400C15L FAQ
The GAFC400C15L 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 air from -5 to 70 C and needs ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl 185 cc, and the unit weighs 1810 g.
The L type is designed for applications that only need up to 0.4 MPa (58 psi), offering finer adjustment in that band. If your machine might ever require more pressure, the standard type (S) with a 0.9 MPa ceiling would be the safer choice.
