About the Airtac GAC F.R.L. Unit GAC400N10ASWK
This GAC400N10ASWK is a three-unit F.R.L. combination - filter, regulator and lubricator - pre-assembled on one L-shape bracket with quick mounting clamps, so there is no inter-unit tubing to leak and commissioning is a single bracket fix. Air passes through the filter first, then the regulator, and the lubricator adds oil mist last, downstream of the regulator seat so the oil never fouls the pressure control.
It is built for a 3/8in port and a 0.15-0.9 MPa (20-130 psi) standard pressure range, with a 5 um filter element for finer particle removal. The nylon bowls hold 100 cc of condensate and 185 cc of oil, and the whole unit weighs 2390 g, so it needs a proper panel or frame mount rather than support from the tubing. A circular gauge is fitted, reading MPa/psi on the default PT thread, and the automatic drain clears water without an operator.

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 GAC400N10ASWK Is Used
CNC machine tooling
Feed a 3/8in line to a CNC spindle or tool changer, where the 5 um element protects precision valves and the automatic drain keeps the line clear during long unattended runs.
Assembly line pallet stops
Supply a bank of pneumatic pallet stops and locating pins on a medium-speed assembly line, using the 185 cc oil bowl to keep multiple actuators lubricated between services.
Packaging machine cylinders
Condition air for a wrapping or cartoning machine's cylinder bank, where the stable 0.15-0.9 MPa regulation holds consistent force for film tension and sealing heads.
Is the Airtac GAC F.R.L. Unit GAC400N10ASWK the Right Air-Prep Unit?
Choose the GAC400 size class when a 3/8in port is needed and the duty sits between the GAC300's 3000 L/min flow envelope and the GAC500's 7000 L/min envelope - the GAC400 curve is plotted to 6000 L/min at 0.7 MPa inlet, so it suits medium-sized machines with multiple actuators. The nylon bowl is a build choice for the environment, and the 5 um element traps far finer particles than the standard 40 um, at the cost of more frequent element service. The automatic drain is decisive for unattended or wet lines, and the reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol with details on its own page. The circular gauge reads MPa/psi on the PT thread, and the spares are GAF400-10, GAR400-10 and GAL400-10, all sharing the same body-port suffix. The 0.15-0.9 MPa range leaves only about 0.1 MPa of headroom above the top setting, so plan a supply near 1.0 MPa if you really need 0.9 MPa out.
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 GAC400N10ASWK FAQ
It operates at 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). The temperature range is -5 to 70 C and it must not freeze. The drain bowl holds 100 cc and the oil bowl 185 cc, the unit weighs 2390 g, and the recommended lubricant is ISO VG 32.
The nylon bowl is a build choice for the environment - the common specification of 1.0 MPa max and -5 to 70 C applies regardless of bowl material, so confirm compatibility for aggressive surroundings. The 5 um element traps far finer particles than the standard 40 um, which suits precision valves or instrument air, but it will need more frequent service.
