Airtac GAC F.R.L. Unit GAC400N15ALNK
The AirTAC Airtac GAC F.R.L. Unit GAC400N15ALNK 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 GAC400N15ALNK
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this GAC400 unit combines a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. It features a 1/2in port, a 40 um element and a nylon bowl. The lower-pressure type restricts the operating range to 0.15-0.4 MPa (20-58 psi). An automatic drain clears condensate without an operator, and a reverse-flow valve is fitted.
Air passes through the filter, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls. No gauge is supplied, but a 1/4in gauge connection allows adding one to read the set pressure. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. The 100 cc drain bowl and 185 cc oil bowl dictate the service interval, and the 2390 g mass requires a firm panel mount rather than tubing support.

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 GAC400N15ALNK Is Used
Textile Machinery
Feeds looms and spinning frames where a lower 0.4 MPa ceiling protects delicate yarn tensioning cylinders from overpressure.
Carton Sealing Lines
Provides steady low-pressure air for folding and gluing stations, with the automatic drain handling condensate in humid environments.
Light Assembly Conveyors
Conditions air for pneumatic stops and diverters, adding oil mist downstream of the regulator to keep moving parts lubricated.
Is the Airtac GAC F.R.L. Unit GAC400N15ALNK the Right Air-Prep Unit?
Choose this nylon-bowl model for unattended lines where the automatic drain prevents condensate buildup. The 1/2in port suits heavier duties than the GAC300, and the catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, double the GAC300 envelope. The 40 um element handles general plant air, while the lower-pressure type limits the ceiling to 0.4 MPa. Because no gauge is supplied, operators must add one to the 1/4in connection to verify settings. The reverse-flow valve is shown as a separate pneumatic symbol in the catalogue. Spares follow the body-port suffix: GAF400-15, GAR400-15 and GAL400-15. Remember that 0.4 MPa is 44% of the standard 0.9 MPa ceiling, so verify your machine never requires higher pressure before selecting this L type.
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 GAC400N15ALNK FAQ
This unit 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 has a 100 cc drain bowl, a 185 cc oil bowl, and weighs 2390 g. The recommended lubricant is ISO VG 32.
The N in the code means no gauge is supplied. The body features a 1/4in gauge connection, allowing you to install a separate gauge reading MPa/psi for the default PT thread to monitor the 0.15-0.4 MPa range.
