Airtac GAC F.R.L. Unit GAC400N10SNK
The AirTAC Airtac GAC F.R.L. Unit GAC400N10SNK 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 GAC400N10SNK
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. The 3/8in port serves standard 0.15-0.9 MPa (20-130 psi) duties, passing air through the 40 um element first so the regulator seat stays dry before the lubricator adds oil mist downstream. A nylon bowl houses the 100 cc condensate sump and 185 cc oil reservoir.
Because the N follows the port code, no pressure gauge is supplied from the factory; operators can add one via the 1/4in gauge connection. The 2390 g assembly uses quick mounting clamps, and this specific SKU includes a reverse-flow (reflux) valve, shown as a separate pneumatic symbol in the catalogue. If the downstream line must remain oil-free, choose a filter-regulator instead of this combination.

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 GAC400N10SNK Is Used
Automated Assembly Lines
Feeds multiple pneumatic cylinders and grippers on a 3/8in loop, providing steady 0.9 MPa pressure and oil mist for moving seals.
Carton Erector Machines
Conditions air for vacuum generators and folding cylinders, relying on the 100 cc drain bowl to capture moisture during long production runs.
Belt Drive Actuation
Supplies lubricated air to pneumatic clutches and brakes on package conveyors, protecting internal components from wear.
Is the Airtac GAC F.R.L. Unit GAC400N10SNK the Right Air-Prep Unit?
This 3/8in model suits machines needing a robust 2390 g assembly without a factory gauge. The nylon bowl saves weight compared to the metal version, while the semi-auto and manual drain pair handles condensate manually or on every pressure drop. Stepping down to a GAC300 halves the plotted flow envelope to 3000 L/min at 0.7 MPa inlet, whereas this body reaches 6000 L/min. The 40 um element fits general plant air, and spares are GAF400-10, GAR400-10 and GAL400-10. The 1.5 MPa proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, but this is not permission to run above 1.0 MPa.
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 GAC400N10SNK FAQ
This standard type unit regulates 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C, weighs 2390 g, has a 100 cc drain bowl, a 185 cc oil bowl, uses a 40 um element, and requires ISO VG 32 lubricant.
The N after the 10 port code means no gauge is supplied, though a 1/4in connection exists to add one. The K indicates a reverse-flow (reflux) valve is fitted, which the catalogue details on its own page.
