Airtac GAC F.R.L. Unit GAC400N10AS
The AirTAC Airtac GAC F.R.L. Unit GAC400N10AS 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 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC400N10AS
Delivering cleaned, regulated and lubricated air for mid-size pneumatic setups, this AirTAC GAC400N10AS combines a filter, regulator and lubricator on a single L-shape bracket. The 3/8in port feeds a standard pressure range of 0.15-0.9 MPa (20-130 psi), while the 40 um element captures solid grain before it reaches downstream valves. Because the units arrive pre-plumbed with quick mounting clamps, installers avoid cutting inter-unit tubing and eliminate those potential leak paths.
The N in the ordering code specifies a nylon bowl, and the A equips the unit with an automatic drain that empties the 100 cc condensate sump without an operator. A circular gauge is fitted, reading MPa/psi for the default PT thread. Air passes through the filter first, then the regulator, so the lubricator adds oil mist last, ensuring oil never fouls the regulating seat. If a machine requires strictly oil-free output downstream, omit the lubricator and choose a separate filter-regulator instead.

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 GAC400N10AS Is Used
Automotive Assembly Lines
Feeds multiple pneumatic impact wrenches and actuators along a vehicle production cell, where the 100 cc auto-drain bowl handles heavy condensate loads continuously.
Carton Erector Machines
Supplies steady 0.9 MPa air to the cylinders folding corrugated boxes, ensuring the lubricator delivers a consistent oil mist to high-cycle moving seals.
Belt Sorting Diverters
Conditions air for high-speed pneumatic pushers on parcel conveyors, relying on the 40 um filter to protect precision diverting valves from particulate ingress.
Is the Airtac GAC F.R.L. Unit GAC400N10AS the Right Air-Prep Unit?
Choose this 2390 g assembly when a smaller GAC300 with its 60 cc drain bowl would require too frequent intervention, as stepping up to the 400 body doubles the condensate capacity. The nylon bowl suits standard plant environments, though buyers should confirm compatibility with aggressive solvents. The automatic drain is decisive for unattended or wet lines, while the fitted gauge lets operators verify the 0.15-0.9 MPa (20-130 psi) setpoint at a glance. Element service uses the 40 um standard, and replacement parts follow the GAF400-10, GAR400-10 and GAL400-10 suffixes. Stepping from the GAC300 to this GAC400 expands the catalogue flow curve envelope from 3000 to 6000 L/min at 0.7 MPa inlet, offering a 2x capacity step for sizing larger duties.
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 GAC400N10AS FAQ
This standard type unit 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). It features a 3/8in port, a 100 cc drain bowl, a 185 cc oil bowl, a 40 um element, and weighs 2390 g. The operating temperature is -5 to 70 C, and the recommended lubricant is ISO VG 32.
The A in the code indicates an automatic drain fitted to the 100 cc sump. It clears accumulated condensate without an operator, which is critical for unattended machinery or environments with high moisture generation, unlike the semi-auto and manual pair found on blank-drain variants.
