Airtac GAFC Air Service Unit GAFC40015ALW
The AirTAC Airtac GAFC Air Service Unit GAFC40015ALW is a genuine two-piece F.R.L. combination — a GA-series filter & regulator and a lubricator pre-assembled on one T-shape bracket with quick mounting clamps. It has 1/2" ports, a 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC40015ALW
This 1/2in port F.R.L. combination joins a filter-regulator body with a lubricator on a single T-bracket, so the air is cleaned, set to pressure, then oil-misted before reaching the machine. The lower-pressure regulator tops out at 0.4 MPa (20-58 psi), which suits delicate circuits that must never see a hard hit of full shop pressure.
The 5 um element traps finer particles than the standard 40 um grade, protecting sensitive valves and instruments downstream. With a 100 cc condensate bowl and a 185 cc oil reservoir, this 1810 g unit needs less frequent attention than smaller GAFC200 or GAFC300 bodies, and the automatic drain clears water without an operator.

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 GAFC40015ALW Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a packaging line with the 5 um filtered, lower-pressure air this unit provides, protecting fine internal clearances from particle wear.
Multi-station assembly
Supply a multi-station assembly machine with a 1/2in header, where the 100 cc condensate bowl and automatic drain handle moisture from a busy compressor room without daily attention.
Lab instrument air
Run a laboratory pick-and-place station that needs clean, regulated air below 0.4 MPa, with the 5 um element keeping instrument orifices clear and the lubricator protecting gripper slides.
Is the Airtac GAFC Air Service Unit GAFC40015ALW the Right Air-Prep Unit?
The GAFC400 body with a 1/2in port sits between the GAFC300 (3/8in, 1020 g) and the GAFC500 (3/4in, 1910 g). The catalogue flow curve for this body is plotted to 6000 L/min at 0.7 MPa inlet, roughly 70% more than the GAFC300's 3500 L/min envelope, so it suits a multi-station line rather than a single actuator. The PC bowl is the standard build; the C and N codes specify metal or nylon bowls, and the shared specification of 1.0 MPa max pressure and -5 to 70 C does not change with the material, so confirm the bowl suits your surroundings before ordering. The automatic drain (A) clears condensate without an operator, ideal for unattended or wet lines. The 5 um element (W) filters finer than the 40 um standard but will need more frequent service. The fitted circular gauge reads in MPa and psi for the default PT thread. Spares are orderable separately as the GAFR400-15 filter & regulator and the GAL400-15 lubricator. With a 1.0 MPa max supply, you have about 0.6 MPa above the 0.4 MPa top of the range, so the regulator has plenty of inlet headroom to hold its setpoint.
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 GAFC40015ALW FAQ
This F.R.L. combination operates from 0.15 to 0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It has a 100 cc condensate bowl, a 185 cc oil bowl, and weighs 1810 g.
The L code specifies a lower-pressure regulator that tops out at 0.4 MPa instead of the standard 0.9 MPa. This suits delicate circuits that must not see full shop pressure. If your machine may ever need more than 0.4 MPa, the standard S type is the correct choice.
