About the Airtac GAC F.R.L. Unit GAC400N10ALW
Delivering cleaned, pressure-set and oil-misted air, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. This specific GAC400N10ALW variant features a 3/8in port, a 5 um element and a nylon bowl. Because the type code is L, the regulating range spans 0.15-0.4 MPa (20-58 psi). The assembly weighs 2390 g, requiring a firm panel or frame mount rather than tubing support.
Air passes through the filter first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls. The automatic drain clears condensate from the 100 cc bowl without an operator, which is decisive for unattended or wet lines. A circular gauge is fitted, reading MPa/psi for the default PT thread, while the 185 cc oil bowl dictates the lubricant refill interval using ISO VG 32 fluid.

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 GAC400N10ALW Is Used
Laboratory Air Tools
Feeds low-pressure air to sensitive laboratory glassware cleaners and agitators requiring a stable 0.4 MPa supply with fine 5 um filtration.
Light Packaging Lines
Conditions air for small pneumatic sealers and label applicators, utilizing the automatic drain to handle condensate during extended shifts.
Precision Textile Machines
Supplies oil-misted air to delicate loom and knitting actuators, protecting moving parts while maintaining strict low-pressure bounds.
Is the Airtac GAC F.R.L. Unit GAC400N10ALW the Right Air-Prep Unit?
Choose this 3/8in port body when a machine needs low-pressure regulation capped at 0.4 MPa; if the equipment might ever require a higher setting, the L type is the wrong part. The 5 um element traps far finer particles than the standard 40 um grade, suiting precision valves or instrument air at the cost of more frequent element service. The nylon bowl offers a different build choice than the standard PC or metal options, so confirm compatibility for aggressive surroundings. If the downstream line must stay completely oil-free, omit the lubricator and choose a filter-regulator instead. Should a component fail, the three units are separately orderable as GAF400-10, GAR400-10 and GAL400-10. Stepping down to the GAC300 reduces the plotted flow envelope from 6000 L/min to 3000 L/min at 0.7 MPa inlet, while the 0.4 MPa ceiling here is 44% of the Standard type's 0.9 MPa maximum.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAC400N10ALW FAQ
This lower-pressure type operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C. It features a 100 cc drain bowl, a 185 cc oil bowl, uses ISO VG 32 lubricant, and weighs 2390 g.
The W code specifies a 5 um element that captures very fine particles for precision pneumatics, requiring closer attention to element service than the standard 40 um filter. The A code signifies an automatic drain, which evacuates condensate from the 100 cc bowl without manual intervention.
