About the Airtac GAFC Air Service Unit GAFC40015LW
This GAFC40015LW is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a shared T-bracket. The 1/2in port and 1810 g mass place it in the mid-size class, where the 100 cc condensate bowl and 185 cc oil bowl support longer intervals between service visits than smaller bodies. It regulates in the lower 0.15-0.4 MPa (20-58 psi) band, with a 5 um element trapping fine particles for sensitive equipment.
Air enters the first body where the filter element removes solids and moisture, and the regulator sets pressure to your dialed value. The lubricator then adds a metered oil mist downstream, so oil never travels back through the regulator seat. A circular gauge is fitted, reading MPa/psi on the PT thread. The semi-auto drain dumps condensate each time pressure drops, while the manual drain offers on-demand release.

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 GAFC40015LW Is Used
Precision Drilling Spindle
Feed a 1/2in port to a precision drilling spindle where the lower 0.4 MPa ceiling protects delicate feed cylinders from over-pressurization, while the 5 um element keeps fine abrasive dust away from spindle bearings.
Assembly Line Press
Supply a small assembly press with regulated air at 0.15-0.4 MPa for controlled clamping force. The 100 cc condensate bowl handles moisture from a humid plant air supply, and the semi-auto drain clears it on each pressure drop.
Machine Tool Lubrication
Use the lubricator to add ISO VG 32 oil mist to a machine tool's slide ways. The 185 cc oil bowl supports extended operation between refills, and the 5 um element protects downstream metering valves from particle wear.
Is the Airtac GAFC Air Service Unit GAFC40015LW the Right Air-Prep Unit?
Choose the GAFC40015LW when your circuit needs a 1/2in port with a lower pressure ceiling of 0.4 MPa (58 psi). The L type suits applications that never require more than this; if your machine may need higher pressure later, select the S type instead. The 5 um element filters finer than the standard 40 um, ideal for precision valves or instrument air, though it will require more frequent element service. The PC bowl is the default build; confirm it suits your environment, as the catalogue provides no material-specific ratings. Both semi-auto and manual drains are fitted, giving automatic dumping on pressure drop plus manual control. The gauge reads MPa/psi, matching the PT thread. For oil-free lines, omit the lubricator and choose a plain GAFR400-15 filter-regulator instead. Spare parts are orderable as GAFR400-15 and GAL400-15. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this unit's regulated range.
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 GAFC40015LW FAQ
The GAFC40015LW operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. It has a 100 cc drain bowl and a 185 cc oil bowl. Recommended lubricant is ISO VG 32. The unit weighs 1810 g.
The L type is designed for circuits that need fine control at lower pressures, topping out at 0.4 MPa instead of the standard 0.9 MPa. This suits delicate actuators or processes where higher pressure could damage equipment. If your application may require more than 0.4 MPa in the future, choose the standard S type instead.
