About the Airtac GAFC Air Service Unit GAFC40015ALN
This GAFC40015ALN is a two-piece F.R.L. combination: a filter-regulator body followed by a lubricator, mounted on a shared T-bracket with quick clamps. The 1/2in port and 1810 g mass put it in the mid-size class, suited for a machine header feeding several actuators. It regulates from 0.15 to 0.4 MPa (20-58 psi) and filters to 40 um.
The automatic drain clears condensate from the 100 cc bowl without operator attention, while the separate 185 cc oil bowl feeds the lubricator. Since the gauge is omitted, the 1/4in gauge connection is available if you add one later. The lower-pressure range tops out at 0.4 MPa, so confirm your circuit never needs more than that.

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 GAFC40015ALN Is Used
Low-Pressure Assembly Fixtures
Feed a pneumatic press or clamping fixture that operates below 0.4 MPa. The automatic drain keeps the 100 cc bowl clear during long production runs, and the 1/2in port delivers adequate flow for a single actuator.
Paint Spray Booth Air
Supply a low-pressure paint atomization line where the regulator is set around 0.3 MPa. The 40 um element removes moisture and particles, while the lubricator adds a controlled oil mist for the spray gun mechanism.
Packaging Machine Tensioning
Use it on a film tensioning station that requires a gentle, stable air pressure below 0.4 MPa. The 185 cc oil bowl supports continuous lubrication, and the automatic drain reduces maintenance checks on a busy line.
Is the Airtac GAFC Air Service Unit GAFC40015ALN the Right Air-Prep Unit?
Choose the GAFC40015ALN when your line needs 1/2in ports and a regulated output capped at 0.4 MPa. The L type suits low-pressure circuits, but if a future process might require up to 0.9 MPa, select the S type instead. The automatic drain is ideal for unattended operation, and the PC bowl is the standard build; confirm it suits your environment. The 40 um element handles general shop air, while the 5 um option is available for finer filtration. With no gauge fitted, plan to use the 1/4in connection if you need to read the set pressure. The PT thread is standard. Spare parts are the GAFR400-15 filter-regulator and GAL400-15 lubricator, both orderable separately. Note that the 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so you have ample inlet margin.
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 GAFC40015ALN FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a maximum supply pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It has a 40 um filter element, a 100 cc drain bowl, and a 185 cc oil bowl. The recommended lubricant is ISO VG 32. The unit weighs 1810 g and is rated for -5 to 70 C. It features an automatic drain and no gauge.
The 'N' in the code indicates the gauge is not supplied. The GAFC400 body has a 1/4in gauge connection port, so you can install a compatible pressure gauge there if you need to read the set pressure. This is useful when the regulator is mounted in a location where a local reading is required.
