Airtac GAC F.R.L. Unit GAC400N10ASNWK
The AirTAC Airtac GAC F.R.L. Unit GAC400N10ASNWK 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 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC400N10ASNWK
Delivering cleaned, regulated and lubricated air for industrial pneumatics, this AirTAC GAC400N10ASNWK combines a filter, regulator and lubricator on a single L-shape bracket. The 3/8in port pairs with a standard 0.15-0.9 MPa (20-130 psi) operating range, while the 5 um element captures fine particulates for sensitive downstream valves. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of the pressure-control mechanism.
Weighing 2390 g, this body size demands a rigid panel or frame mount rather than tubing support. The unit carries a nylon bowl and an automatic drain that empties the 100 cc condensate sump without operator intervention. No pressure gauge is supplied, but a 1/4in connection is provided if you need to add one later. A reverse-flow (reflux) valve is fitted, shown in the catalogue as a separate pneumatic symbol on its own page.

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 GAC400N10ASNWK Is Used
CNC Tool Changers
Feeds sensitive pneumatic tool changers where the 5 um element protects precision valves from fine particulate ingress.
Textile Machinery
Conditions air for multi-station textile looms, utilizing the automatic drain to handle humid plant environments.
Carton Sealers
Supplies steady lubricated air to high-cycle carton sealing actuators, ensuring consistent movement and reducing wear.
Is the Airtac GAC F.R.L. Unit GAC400N10ASNWK the Right Air-Prep Unit?
This model uses a 5 um element instead of the standard 40 um, trading a slightly shorter service life for the cleaner air required by precision instruments. The automatic drain makes it suitable for unattended or high-moisture lines, while the nylon bowl offers a lightweight alternative to the standard PC or metal bowls. If your process requires absolutely oil-free air downstream, you must omit the lubricator and choose a dedicated filter-regulator instead. For maintenance, the assembly accepts individual GAF400-10, GAR400-10 and GAL400-10 replacement units. The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, which is double the GAC300's 3000 L/min envelope, giving you significant room to size up. Additionally, the 1.5 MPa (215 psi) proof pressure provides a 1.5x burst-test margin above the 1.0 MPa maximum, though this does not permit running 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 GAC400N10ASNWK 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 1.5 MPa (215 psi) proof pressure. 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 features a 1/4in gauge connection, allowing you to install a compatible pressure indicator if monitoring the 0.15-0.9 MPa setpoint is required for your application.
