About the Airtac GAFC Air Service Unit GAFC40015L
This GAFC40015L 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, where a proper panel or frame mount is expected rather than support from the tubing. It filters to 40 um, regulates to a lower 0.15-0.4 MPa (20-58 psi) band, and then adds a metered oil mist downstream.
Air passes through the filter and regulator first, so oil never travels back across the regulator seat. The 100 cc condensate bowl and 185 cc oil bowl are the real service interval drivers, and this body's capacity means fewer visits than a smaller unit. A circular gauge is fitted, reading MPa and psi on the default PT thread scale. The lower pressure range suits delicate circuits, but the 1.0 MPa (145 psi) max supply leaves about 0.6 MPa above the 0.4 MPa top of the range.

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 GAFC40015L Is Used
Precision Pressure Control
Feed a precision grinding spindle or a tensioning device that needs a stable, lower air pressure below 0.4 MPa, where the L-type regulator's range is a direct match.
Assembly Line Lubrication
Supply a multi-station assembly fixture with filtered, regulated air and a controlled oil mist for pneumatic screwdrivers or push-in fittings, using the 185 cc oil bowl to extend runtime.
Test Rig Air Prep
Prepare air for a laboratory test jig or a calibration bench that requires clean, lubricated air at a precise low pressure, with the 100 cc drain bowl handling condensate from humid shop supply.
Is the Airtac GAFC Air Service Unit GAFC40015L the Right Air-Prep Unit?
Choose the GAFC400 for a 1/2in line that needs more condensate and oil capacity than the GAFC300's 60 cc and 98 cc bowls, while staying lighter than the GAFC500's 1910 g. The L type caps regulation at 0.4 MPa (20-58 psi), so if the machine may ever need more pressure, step to the S type instead. The blank drain code fits both a semi-auto drain, which dumps on pressure drop, and a manual drain for on-demand use. The PC bowl is the standard build; confirm it suits your environment, as the catalogue gives no material-specific limits. The 40 um element is the default, with a 5 um option for finer filtration. Spare parts are orderable as the GAFR400-15 filter & regulator and the GAL400-15 lubricator. The 1.0 MPa max supply is 0.6 MPa above this unit's 0.4 MPa ceiling, so plan the 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 GAFC40015L FAQ
The GAFC40015L operates at 0.15-0.4 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 is rated for -5 to 70 C and uses ISO VG 32 oil. The unit weighs 1810 g and has a 100 cc condensate bowl and a 185 cc oil bowl. The 40 um filter element is standard.
The L in the code specifies the lower-pressure type, which regulates from 0.15 to 0.4 MPa (20-58 psi) instead of the standard 0.15-0.9 MPa. This is for circuits that must not exceed 0.4 MPa. The gauge is fitted and reads MPa and psi, so you can verify the setpoint directly.
