About the Airtac GAC F.R.L. Unit GAC400C10SNWK
Delivering cleaned, regulated and lubricated air for mid-size pneumatic setups, the AirTAC GAC400C10SNWK is a three-unit F.R.L. combination pre-plumbed on a single L-shape bracket. This specific build features a 3/8in port, a durable metal bowl, and a 5 um element for trapping fine particles before they reach precision valves. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of internal components.
Operating at a standard pressure range of 0.15-0.9 MPa (20-130 psi), this unit omits the pressure gauge to allow custom instrumentation via its 1/4in gauge connection. The 100 cc condensate bowl and 185 cc oil reservoir dictate the maintenance rhythm, requiring fewer interventions than smaller bodies. A reverse-flow (reflux) valve is fitted, which the catalogue shows 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 GAC400C10SNWK Is Used
CNC Tooling Feed
Supplies finely filtered, lubricated air to pneumatic tool changers and actuators on CNC machining centers.
Carton Erector Lines
Conditions air for high-speed packaging equipment where consistent pressure and fine 5 um filtration prevent valve sticking.
Stamping Press Valves
Prepares drive air for heavy-duty stamping press pneumatic logic, relying on the 100 cc drain bowl for wet shop environments.
Is the Airtac GAC F.R.L. Unit GAC400C10SNWK the Right Air-Prep Unit?
Choose this 2390 g assembly when your application demands fine 5 um filtration and a rugged metal bowl within the GAC400 size class. The semi-auto and manual drain pair is fitted as standard, dumping condensate on pressure drops or on demand. If your machine requires oil-free air downstream, you must omit the lubricator and select a filter-regulator instead. For maintenance, the three modules are separately orderable as GAF400-10, GAR400-10 and GAL400-10, sharing the exact same body and port suffix. The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, which is double the GAC300's 3000 L/min envelope, giving you significant sizing headroom. Additionally, the 1.5 MPa (215 psi) proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, but this is not permission to run above 1.0 MPa.
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 GAC400C10SNWK FAQ
