Airtac GAC F.R.L. Unit GAC400N10SN
The AirTAC Airtac GAC F.R.L. Unit GAC400N10SN 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 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC400N10SN
Delivering cleaned, regulated and lubricated air, this AirTAC GAC400N10SN assembly integrates a filter, regulator and lubricator on a single L-shape bracket with quick clamps. It features a 3/8in port, a 40 um element and a standard pressure range of 0.15-0.9 MPa (20-130 psi). The nylon bowl equips this unit for environments where polymer transparency is preferred, while the build order ensures oil mist is added downstream of the regulator so the internal seat never fouls.
Because the code carries an N after the port, no pressure gauge is supplied; you can add one via the 1/4in gauge connection. Weighing 2390 g, this body demands a solid panel or frame mount rather than tubing support. It ships with both a semi-auto drain that dumps condensate on every pressure drop and a manual drain for on-demand emptying into the 100 cc bowl.

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 GAC400N10SN Is Used
Automotive Assembly Lines
Feeds pneumatic impact wrenches and actuators on a vehicle production track, supplying steady 0.6 MPa pressure and oil mist for high-cycle tooling.
Carton Erector Machines
Prepares air for the folding cylinders and vacuum cups on a high-speed packaging line, trapping 40 um particulates before they reach the valves.
Belt Sorting Diverters
Conditions air for rapid pneumatic pushers on a logistics conveyor, relying on the 100 cc condensate bowl to capture moisture from continuous duty.
Is the Airtac GAC F.R.L. Unit GAC400N10SN the Right Air-Prep Unit?
This 3/8in port model suits mid-scale pneumatic duties, plotting a flow envelope to 6000 L/min at 0.7 MPa inlet, which is double the GAC300's 3000 L/min capacity. The 40 um element handles general plant air, whereas the 5 um W option targets precision instrumentation. If your line must remain oil-free, omit the lubricator and choose a separate filter-regulator instead. For maintenance, the assembly accepts GAF400-10, GAR400-10 and GAL400-10 replacement units. The 1.5 MPa (215 psi) proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, confirming structural safety without permitting operation above the rated ceiling.
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 GAC400N10SN FAQ
This standard type unit regulates from 0.15-0.9 MPa (20-130 psi) with a maximum 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, holds 100 cc of condensate and 185 cc of oil, and uses ISO VG 32 lubricant.
The N after the port code means no gauge is supplied from the factory. You can install your own circular gauge in the 1/4in threaded connection, reading MPa/psi for the default PT thread, to verify the downstream setpoint.
