About the Airtac GAC F.R.L. Unit GAC400N15ALNWK
Delivering cleaned, regulated and lubricated air for pneumatic systems, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. It features a 1/2in port, a 5 um element for fine particle capture, and a lower pressure range of 0.15-0.4 MPa (20-58 psi). The build routes air through the filter first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls.
This specific configuration uses a nylon bowl and an automatic drain to clear condensate without an operator, which is decisive for unattended or wet lines. No gauge is supplied, but a 1/4in gauge connection allows adding one later if reading the set pressure becomes necessary. The reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol with details on its own page.

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 GAC400N15ALNWK Is Used
Precision Valve Lines
Feeds sensitive directional control valves requiring finely filtered, lubricated air at stable low pressures.
Packaging Machinery
Conditions air for moving parts in flow wrappers, protecting seals with a steady oil mist downstream.
Laboratory Pneumatics
Prepares supply for test fixtures needing 5 um filtration and low-pressure regulation without manual draining.
Is the Airtac GAC F.R.L. Unit GAC400N15ALNWK the Right Air-Prep Unit?
Choose this 2390 g assembly when a machine requires low-pressure air capped at 0.4 MPa and high filtration. The 5 um element traps far finer particles than the standard 40 um grade, suiting precision valves or instrument air, though it requires more frequent element service. Because the lubricator injects oil mist downstream, select a filter-regulator instead if the application must remain oil-free. Should a component fail, the three units are separately orderable as GAF400-15, GAR400-15 and GAL400-15. The 0.4 MPa ceiling is 44% of the Standard type's 0.9 MPa maximum, so confirm your machinery will never need higher pressure before specifying this L-type unit.
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 GAC400N15ALNWK FAQ
This lower-pressure F.R.L. combination operates at 0.15-0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It has a 100 cc drain bowl, a 185 cc oil bowl, a 5 um element, and weighs 2390 g. The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32.
The N in the code means no gauge is supplied, so the set pressure cannot be read without adding one. The body features a 1/4in gauge connection, allowing you to install a compatible gauge reading MPa/psi for the default PT thread if visual monitoring is required.
