Airtac GAC F.R.L. Unit GAC400N10ASW
The AirTAC Airtac GAC F.R.L. Unit GAC400N10ASW 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 GAC400N10ASW
Delivering cleaned, regulated and lubricated air for mid-size pneumatic setups, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/8in port serves systems needing a 0.15-0.9 MPa (20-130 psi) operating range, while the 5 um element captures fine particulates before they reach sensitive 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.
Built with a nylon bowl, the assembly includes an automatic drain that expels condensate without operator intervention, a decisive feature for unattended or wet lines. The unit carries a 100 cc condensate bowl and a 185 cc oil reservoir, setting the maintenance interval for a 2390 g assembly that requires a firm panel or frame mount rather than tubing support. A circular gauge is fitted, reading MPa/psi for the default PT thread, so technicians can verify the set pressure directly at the unit.

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 GAC400N10ASW Is Used
CNC Tool Changing Systems
Feeds precision actuators and tool changers on CNC machining centers where the 5 um element protects sensitive proportional valves from fine particulate ingress.
Automated Filling Lines
Conditions air for high-speed bottling and capping machinery, utilizing the automatic drain to handle condensate continuously during multi-shift operations.
Textile Manufacturing Headers
Supplies regulated, lubricated air to multi-station weaving or spinning equipment where consistent pressure and oil mist protect fast-moving loom components.
Is the Airtac GAC F.R.L. Unit GAC400N10ASW the Right Air-Prep Unit?
Choose this GAC400 unit when a machine demands precision filtration and unattended condensate management in a 3/8in line. The 5 um element offers tighter protection for instrument air or sensitive valves compared to the standard 40 um grade, though it requires more frequent element replacement. If the downstream process must remain strictly oil-free, this lubricator-equipped assembly is the wrong choice and a dedicated filter-regulator should be selected instead. For maintenance, the individual components are separately orderable as GAF400-10, GAR400-10 and GAL400-10, meaning a clogged screen or damaged bowl does not require replacing the whole assembly.
When sizing the air supply, note that the catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, which is exactly double the 3000 L/min envelope of the GAC300. Additionally, the 1.5 MPa (215 psi) proof pressure provides a 1.5x burst-test margin over the 1.0 MPa (145 psi) maximum operating limit, but this is strictly a safety rating and 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 GAC400N10ASW FAQ
This model operates within a 0.15-0.9 MPa (20-130 psi) standard pressure range, with a maximum 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, and the recommended lubricant is ISO VG 32. It features a 3/8in port, a 100 cc drain bowl, a 185 cc oil bowl, and weighs 2390 g.
The 5 um element traps far finer particles than the standard 40 um filter, making it ideal for protecting precision valves and instrument air, though it will require more frequent service. The automatic drain clears accumulated condensate from the 100 cc nylon bowl without an operator, which is essential for unattended machinery or environments with high moisture loads.
