Airtac GAC F.R.L. Unit GAC400N15SN
The AirTAC Airtac GAC F.R.L. Unit GAC400N15SN 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 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC400N15SN
Delivering cleaned, regulated and lubricated air for mid-sized pneumatics, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. The 1/2in port serves machines needing a robust supply, while the standard type governs pressure across 0.15-0.9 MPa (20-130 psi) and the 40 um element captures standard particulates.
This variant uses a nylon bowl and ships without a gauge, leaving the 1/4in gauge connection open for you to fit a preferred indicator. Weighing 2390 g, the assembly requires a firm panel or frame mount rather than tubing support. The 100 cc condensate sump and 185 cc oil reservoir set the maintenance rhythm, and the semi-auto drain dumps water on every pressure drop.

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 GAC400N15SN Is Used
Automotive Assembly Lines
Feeds main air headers for multi-station welding jigs where a steady 1/2in supply and regular oil mist keep robotic actuators cycling smoothly.
Carton Erector Machines
Conditions air for high-speed folding and sealing cylinders, relying on the 100 cc drain bowl to capture moisture during continuous daily shifts.
Belt Sorting Diverters
Supplies pneumatic pop-up sorters on logistics conveyors, using the 40 um filtration to protect directional valves from plant grit.
Is the Airtac GAC F.R.L. Unit GAC400N15SN the Right Air-Prep Unit?
Choose this GAC400 unit for 1/2in lines where operators will add their own pressure gauge via the 1/4in connection. The 40 um element suits general plant air, whereas a 5 um variant is better for precision valves. Its nylon bowl matches the 1.0 MPa max pressure of the standard build, but confirm chemical compatibility for aggressive environments. If your downstream line must stay oil-free, omit the lubricator and choose a filter-regulator instead. Spares are straightforward: order GAF400-15, GAR400-15 and GAL400-15. The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, which is roughly 2x the 3000 L/min envelope of the smaller GAC300. Stepping up to the GAC500 brings a 7000 L/min curve, so size carefully. Finally, the 1.5 MPa proof pressure against the 1.0 MPa maximum provides a 1.5x burst-test margin, not permission to run above 1.0 MPa.
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 GAC400N15SN FAQ
This standard type unit regulates from 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, weighs 2390 g, and features a 100 cc drain bowl with a 185 cc oil bowl. The recommended lubricant is ISO VG 32.
The N in the ordering code indicates no gauge is supplied. The body has a 1/4in gauge connection, allowing you to mount a preferred pressure indicator directly to the unit. You must add a gauge to read and verify the set downstream pressure.
