Airtac GAC F.R.L. Unit GAC400N15ALN
The AirTAC Airtac GAC F.R.L. Unit GAC400N15ALN 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 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC400N15ALN
Delivering cleaned, regulated and lubricated air for pneumatic systems, this AirTAC unit integrates a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. The 1/2in port GAC400 body features a nylon bowl and a 40 um element, operating within the lower pressure range of 0.15-0.4 MPa (20-58 psi). Weighing 2390 g, it is designed for panel or frame mounting rather than tubing support.
The internal air path moves through the filter first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls. Equipped with an automatic drain that clears condensate without operator intervention, the unit holds 100 cc in its drain bowl and 185 cc in its oil reservoir. No gauge is supplied, but a 1/4in connection is available if pressure monitoring is added later.

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 GAC400N15ALN Is Used
Low-Pressure Packaging Lines
Feeds delicate pneumatic clamps on flow-wrapping equipment where operating pressures must stay below 0.4 MPa to prevent crushing lightweight cartons.
Textile Manufacturing
Conditions air for spinning and weaving actuators that require consistent oil mist and steady low-pressure regulation to protect fragile fibers.
Laboratory Automation
Prepares supply air for benchtop fluid dispensing robots, using the automatic drain to handle condensate in intermittently run systems.
Is the Airtac GAC F.R.L. Unit GAC400N15ALN the Right Air-Prep Unit?
Choose this model for 1/2in ported lines requiring low-pressure regulation up to 0.4 MPa, where an automatic drain suits unattended or wet environments. The nylon bowl offers a lightweight alternative to metal or PC constructions, though buyers must confirm chemical compatibility for aggressive surroundings. If your downstream line must remain strictly oil-free, you should select a filter-regulator instead of this combination, as the lubricator intentionally adds oil mist to the air stream. Should a component fail, the assembly splits into separately orderable spares using the GAF400-15, GAR400-15 and GAL400-15 part numbers.
When sizing the unit, note that the catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, which is roughly double the 3000 L/min envelope of the GAC300. Finally, choosing this lower-pressure type means the 0.4 MPa ceiling is just 44% of the standard 0.9 MPa maximum, so it is the wrong part if the machine may ever need higher pressure.
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 GAC400N15ALN FAQ
This lower-pressure type 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). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It features a 1/2in port, weighs 2390 g, and has a 100 cc drain bowl capacity alongside a 185 cc oil bowl capacity.
The N in the product code indicates that no circular gauge is supplied. If you need to monitor the set pressure, the body features a 1/4in gauge connection that allows you to install a separate gauge reading in MPa or psi to match the default PT thread.
