Airtac GAC F.R.L. Unit GAC400N10S
The AirTAC Airtac GAC F.R.L. Unit GAC400N10S 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 GAC400N10S
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 port pairs with a standard pressure range of 0.15-0.9 MPa (20-130 psi) and a 40 um element. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of the internal valve mechanism.
The nylon bowl equips this assembly for environments where chemical resistance or visibility of the condensate level is prioritized. A circular gauge is fitted, reading MPa/psi for the default PT thread, so operators can verify the set pressure at a glance. Condensate management relies on a semi-auto and manual drain pair, with the 100 cc drain bowl dictating routine maintenance intervals.

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 GAC400N10S Is Used
Automated Assembly Lines
Feeds multiple pneumatic grippers and actuators on a production cell, ensuring consistent pressure and clean lubricated air for high-cycle operations.
Carton Erecting Machines
Conditions air for vacuum cups and sealing cylinders, where stable regulation prevents misfeeds during high-speed cardboard handling.
CNC Tool Changers
Supplies air to pneumatic tool release mechanisms, relying on the 40 um element to protect precision valves from particulate ingress.
Is the Airtac GAC F.R.L. Unit GAC400N10S the Right Air-Prep Unit?
Choose this 2390 g body when a machine demands a robust air preparation footprint that cannot be supported by tubing alone; stepping down to the GAC300 halves the plotted flow envelope to 3000 L/min at 0.7 MPa inlet. If the application requires oil-free output downstream, omit the lubricator and select a dedicated filter-regulator instead. The nylon bowl shares the same 1.0 MPa maximum pressure as metal and PC variants, but buyers should confirm compatibility with aggressive solvents. Replacement spares follow the body-port suffix exactly: GAF400-10, GAR400-10 and GAL400-10. The 1.5 MPa proof pressure provides a 1.5x burst-test margin above the 1.0 MPa maximum operating limit.
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 GAC400N10S FAQ
This standard type unit operates at 0.15-0.9 MPa (20-130 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It features a 3/8in port, a 40 um element, a nylon bowl, and a semi-auto + manual drain. The drain bowl capacity is 100 cc and the oil bowl is 185 cc. The operating temperature is -5 to 70 C, the weight is 2390 g, and the recommended lubricant is ISO VG 32.
This configuration ships with both a semi-auto and a manual drain fitted. The semi-auto mechanism expels condensate automatically during each pressure drop, while the manual option allows on-demand drainage by the operator. This dual-drain approach suits lines that experience intermittent moisture buildup.
