Airtac GAC F.R.L. Unit GAC400N15ALW
The AirTAC Airtac GAC F.R.L. Unit GAC400N15ALW is a genuine three-unit F.R.L. combination — a filter, a pressure regulator and a lubricator pre-assembled on one 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 GAC F.R.L. Unit GAC400N15ALW
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC GAC400N15ALW combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port pairs with a 5 um element to capture fine particulates before they reach sensitive valves. Because the lubricator sits downstream of the regulator, the oil mist never fouls the pressure-control seat. A circular gauge is fitted, reading MPa/psi for the default PT thread.
Built with a nylon bowl, the unit carries a 100 cc condensate sump and a 185 cc oil reservoir. The automatic drain clears accumulated water without an operator, making it well-suited for unattended or wet lines. Operating pressure spans 0.15-0.4 MPa (20-58 psi), and the 2390 g mass requires a solid panel or frame mount rather than tubing support. If your machine might ever demand higher pressure, this lower-range type is the wrong part.

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 GAC F.R.L. Unit GAC400N15ALW Is Used
Laboratory Pneumatic Stations
Feeds low-pressure air to sensitive analytical instruments and actuators, relying on the 5 um element to prevent particulate contamination.
Light-Clamp Packaging Lines
Regulates gentle handling forces for flow-wrapping and cartoning machines, using the 0.4 MPa ceiling to avoid crushing delicate goods.
Textile Spinning Frames
Provides a steady, lubricated supply to air-jet looms and texturing valves where excessive pressure would snap fine yarns.
Is the Airtac GAC F.R.L. Unit GAC400N15ALW the Right Air-Prep Unit?
Choose this nylon-bowl assembly when you need fine 5 um filtration and automatic condensate evacuation alongside a strict 0.15-0.4 MPa (20-58 psi) output ceiling. The fitted gauge reads MPa/psi, allowing operators to verify the low-pressure setting directly. Should your downstream line require absolutely oil-free air, you must omit the lubricator and select a dedicated filter-regulator instead. For maintenance, the three components are separately orderable as GAF400-15, GAR400-15 and GAL400-15, meaning a clogged filter or damaged bowl does not force replacing the whole assembly. Stepping up from the GAC300 gives roughly double the flow envelope, with the catalogue curve for this body plotted to 6000 L/min at 0.7 MPa inlet versus 3000 L/min on the smaller neighbour. Finally, choosing this L type means accepting a 44% ceiling compared to the 0.9 MPa maximum of the standard version.
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 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 2390 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 filter-regulator instead of an F.R.L. combination on that branch.
Airtac GAC F.R.L. Unit GAC400N15ALW FAQ
This lower-pressure unit regulates from 0.15-0.4 MPa (20-58 psi) against a 1.0 MPa (145 psi) maximum and a 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C, weighs 2390 g, and pairs a 100 cc drain bowl with a 185 cc oil bowl. The recommended lubricant is ISO VG 32.
The W code specifies a 5 um element, trapping far finer particles than the standard 40 um grade for precision valves, at the cost of more frequent element service. The A code denotes an automatic drain that evacuates condensate from the 100 cc sump without operator intervention, which is decisive for unattended machinery.
