Airtac GAC F.R.L. Unit GAC400N15SK
The AirTAC Airtac GAC F.R.L. Unit GAC400N15SK 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 1/2" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC400N15SK
Delivering cleaned, regulated and lubricated air for mid-size pneumatic setups, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port serves standard 0.15-0.9 MPa (20-130 psi) duties, while the 40 um element captures particulates before they reach downstream valves. A circular gauge is fitted to read the set pressure in MPa/psi for the default PT thread.
The build routes air through the filter first, then the regulator, adding oil mist last so the internal seat never fouls. This variant uses a nylon bowl and includes a reverse-flow (reflux) valve, which the catalogue shows as a separate pneumatic symbol with details on its own page. Weighing 2390 g, the assembly needs a firm panel or frame mount rather than relying on the tubing for support.

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 GAC400N15SK Is Used
Automotive Assembly Lines
Feeds multiple pneumatic torque wrenches and actuators on a car plant conveyor, relying on the 1/2in port to maintain steady pressure during high-demand shift cycles.
Carton Erecting Machines
Conditions air for the suction cups and folding cylinders in continuous packaging equipment, where the 40 um element prevents dust from clogging critical ejector nozzles.
Lab Pneumatic Test Benches
Supplies regulated, lubricated air to instrument valves and grippers on a testing rig, allowing technicians to monitor the exact downstream pressure via the fitted circular gauge.
Is the Airtac GAC F.R.L. Unit GAC400N15SK the Right Air-Prep Unit?
Choose this body for medium flow requirements, as the catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, double the GAC300's 3000 L/min envelope. The semi-auto and manual drain pair both ship fitted to the 100 cc condensate bowl, giving an operator flexibility during routine maintenance. If your application requires completely oil-free output downstream, omit the lubricator and select a dedicated filter-regulator instead. Replacement parts are available as GAF400-15, GAR400-15 and GAL400-15. The 1.5 MPa (215 psi) proof pressure against the 1.0 MPa (145 psi) maximum provides a 1.5x burst-test margin, which is not permission to run above the 1.0 MPa limit.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAC400N15SK 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 functions within a -5 to 70 C temperature range, features a 100 cc drain bowl and a 185 cc oil bowl, uses ISO VG 32 lubricant, and weighs 2390 g.
The K indicates that a reverse-flow (reflux) valve is attached to the assembly. The official catalogue draws this as a separate pneumatic symbol with details on its own page, representing an ordering difference for specific line requirements.
