Airtac GAC F.R.L. Unit GAC400N10LN
The AirTAC Airtac GAC F.R.L. Unit GAC400N10LN 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 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC400N10LN
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. It features a 3/8in port, a 40 um element and a nylon bowl. Because the type code is L, the pressure range is 0.15-0.4 MPa (20-58 psi). The 2390 g mass requires a firm panel or frame mount rather than tubing support.
Air passes through the filter first, then the regulator, before oil mist is introduced by the lubricator. This sequence prevents oil from fouling the regulator seat. The 100 cc condensate bowl and 185 cc oil sump dictate the maintenance interval, and the semi-auto drain dumps liquid on every pressure drop. No gauge is supplied, but a 1/4in connection is ready if you need to add one later.

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 GAC400N10LN Is Used
Textile Machinery
Feeds low-pressure air to loom actuators where delicate fabric handling demands a strict 0.15-0.4 MPa operating range.
Carton Erectors
Supplies steady, lubricated air to moving folding arms and vacuum grippers, with the 100 cc drain handling condensate from long runs.
Belt Diverters
Conditions air for pneumatic pushers on sorting lines, relying on the 3/8in port to maintain steady flow to rapid cylinders.
Is the Airtac GAC F.R.L. Unit GAC400N10LN the Right Air-Prep Unit?
This model uses a nylon bowl and a semi-auto plus manual drain. If your line must stay completely oil-free, you should choose a filter-regulator instead, because this lubricator adds oil mist downstream. The three components are also sold separately as GAF400-10, GAR400-10 and GAL400-10, so a damaged bowl does not force replacing the whole assembly. The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, double the 3000 L/min envelope of the GAC300. The 0.4 MPa ceiling is 44% of the 0.9 MPa standard limit, so confirm your machinery will never need higher pressure.
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 GAC400N10LN FAQ
It operates at 0.15-0.4 MPa (20-58 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. It has a 100 cc drain bowl, a 185 cc oil bowl, weighs 2390 g, and uses ISO VG 32 lubricant.
No, because the N after the port means no gauge is supplied. The body has a 1/4in gauge connection, so you can install a separate gauge reading MPa/psi for the default PT thread to monitor your downstream setting.
