Airtac GAC F.R.L. Unit GAC400C10ASNK
The AirTAC Airtac GAC F.R.L. Unit GAC400C10ASNK 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 GAC400C10ASNK
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/8in port serves machines needing a steady 0.15-0.9 MPa (20-130 psi) output, while the 40 um element captures particulate before it reaches downstream valves. Because the units arrive pre-plumbed with quick mounting clamps, installers avoid inter-unit tubing leaks and only need to secure one assembly.
This specific configuration uses a robust metal bowl paired with an automatic drain that empties condensate without an operator, making it well-suited for wet lines or unattended stations. No pressure gauge is supplied, though a 1/4in connection is ready if you need to add one later. The build sequence places the lubricator last, so oil mist is added downstream of the regulator seat to prevent fouling. A reverse-flow (reflux) valve is fitted, which the catalogue depicts as a separate pneumatic symbol with details on its own page.

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 GAC400C10ASNK Is Used
Automotive Assembly Lines
Feeds multiple pneumatic torque wrenches and actuators on a vehicle production line, relying on the automatic drain to handle moisture in high-cycle duty.
Case Erector Machines
Provides consistent 0.6 MPa air to folding and sealing cylinders in continuous packaging operations, with the metal bowl resisting shop-floor impacts.
Material Handling Systems
Conditions air for diverter gates and sorting cylinders on a 3/8in pneumatic circuit, ensuring oil mist reaches moving parts to prevent wear.
Is the Airtac GAC F.R.L. Unit GAC400C10ASNK the Right Air-Prep Unit?
Choose this 2390 g assembly when a frame or panel mount is available, as the body needs rigid support rather than tubing. The metal bowl suits harsher industrial settings, and buyers should confirm chemical compatibility for aggressive surroundings. Since no gauge is included, the set pressure cannot be read without adding one to the 1/4in port. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. For maintenance, the three units are separately orderable as GAF400-10, GAR400-10 and GAL400-10, meaning a clogged element does not require replacing the whole assembly. The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, which is exactly double the GAC300's 3000 L/min envelope, giving clear sizing headroom. Stepping up to this body also scales service intervals, as its 100 cc condensate bowl holds roughly 1.7x the capacity of the GAC300's 60 cc bowl.
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.
