About the Airtac GAC F.R.L. Unit GAC400N10LW
Delivering cleaned, regulated and lubricated air for pneumatic systems, this AirTAC unit integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/8in ported body houses a 5 um element for trapping fine particles, while the lower pressure type governs output strictly between 0.15-0.4 MPa (20-58 psi). A circular gauge is fitted, reading MPa/psi for the default PT thread.
Air passes through the filter first, then the regulator, ensuring oil mist from the lubricator is added last so it never fouls the regulator seat. The nylon bowl equips this assembly with a 100 cc condensate capacity and a 185 cc oil reservoir, requiring panel mounting to support its 2390 g mass. Condensate is expelled via a semi-auto and manual drain 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 GAC400N10LW Is Used
Precision Valve Arrays
Feeds instrument-quality air to sensitive solenoid valve banks using the 5 um element to prevent spool sticking.
Laboratory Pneumatics
Regulates low-pressure air for delicate test fixtures that require stable 0.15-0.4 MPa outputs without risking over-pressurization.
Light Packaging Lines
Conditions air for small pick-and-place actuators, adding the exact oil mist needed to prolong cylinder seals.
Is the Airtac GAC F.R.L. Unit GAC400N10LW the Right Air-Prep Unit?
Choose this configuration when a 3/8in line requires precision filtration and low outlet pressures. The 5 um element catches far finer particulates than the standard 40 um grade, making it ideal for sensitive valves, though it will require more frequent element replacement. If the machinery might ever demand more than 0.4 MPa, the L type is the wrong choice, as it caps out well below the standard 0.9 MPa ceiling. Because oil mist is injected downstream, select a filter-regulator instead if the application requires strictly oil-free air downstream. Replacement parts share the same body-port suffix: order GAF400-10, GAR400-10 and GAL400-10 individually. Stepping down to the GAC300 halves the plotted flow envelope to 3000 L/min at 0.7 MPa inlet, whereas this 400 body reaches 6000 L/min. The 0.4 MPa upper limit of this lower-pressure type is just 44% of the standard 0.9 MPa 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 GAC400N10LW FAQ
This lower-pressure type regulates from 0.15-0.4 MPa (20-58 psi). It shares a 1.0 MPa (145 psi) maximum pressure and a 1.5 MPa (215 psi) proof pressure across the series. Operating temperature is -5 to 70 C, using ISO VG 32 lubricant. The unit weighs 2390 g, features a 100 cc drain bowl and a 185 cc oil bowl.
The nylon bowl provides a durable, shatter-resistant alternative to standard PC without changing the 1.0 MPa pressure rating. The fitted semi-auto drain expels condensate automatically whenever the system pressure drops, but also includes a manual override for on-demand emptying between cycles.
