Airtac GAFC Air Service Unit GAFC40015AL
The AirTAC Airtac GAFC Air Service Unit GAFC40015AL 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 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAFC Air Service Unit GAFC40015AL
This F.R.L. combination pairs a filter-regulator with a lubricator on a shared T-bracket, so the air is cleaned, set to pressure, then given a metered oil mist in the last stage. With a 1/2in port and a 1810 g mass, the GAFC40015AL suits a machine header feeding several actuators rather than a single small cylinder.
The lower-pressure regulator is set for 0.15-0.4 MPa (20-58 psi), and the 40 um element handles standard shop air. The automatic drain clears condensate from the 100 cc bowl without an operator, while the 185 cc oil bowl keeps the lubricator supplied for long runs. A circular gauge with an MPa/psi scale is fitted, and the PT thread matches common local piping.

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 GAFC40015AL Is Used
Precision pressure setting
Set a precise 0.3 MPa for a delicate clamping fixture on a CNC machine, where the lower-pressure range gives finer adjustment than a standard regulator.
Multi-station assembly line
Feed a 1/2in header on a small assembly line that runs several pneumatic screwdrivers, with the automatic drain handling condensate from a busy shift.
Packaging machine air prep
Protect a packaging machine's pneumatic cylinders and valves with filtered, regulated, and lubricated air, sized for the 1/2in port and 1810 g body.
Is the Airtac GAFC Air Service Unit GAFC40015AL the Right Air-Prep Unit?
Choose the GAFC40015AL when your line needs a regulated top pressure of 0.4 MPa and a 1/2in port. The L type is the lower-pressure version, so if the machine may ever need more than 0.4 MPa, step up to the standard S type instead. The automatic drain is the right call for unattended equipment, and the PC bowl is the standard build - confirm it suits your environment, as the catalogue gives no material-specific ratings.
The element is 40 um, and the gauge reads in MPa/psi with the PT thread. Spare parts are orderable as the GAFR400-15 filter-regulator and the GAL400-15 lubricator. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range, so plan your 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 GAFC40015AL FAQ
The GAFC40015AL 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). It has a 100 cc drain bowl and a 185 cc oil bowl, weighs 1810 g, and works in -5 to 70 C temperatures. Use ISO VG 32 oil in the lubricator.
The L in the code means the regulator is set for a 0.15-0.4 MPa range instead of the standard 0.15-0.9 MPa. This gives finer control for low-pressure applications, but if your equipment ever needs more than 0.4 MPa, you would need the standard S type instead.
