About the Airtac GAC F.R.L. Unit GAC400N10SNWK
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC F.R.L. combination pre-assembles a filter, regulator and lubricator on a single L-shape bracket. The 3/8in port serves a 2390 g unit that conditions supply within a 0.15-0.9 MPa (20-130 psi) standard pressure range. A 5 um element captures fine particulates, while the nylon bowl equips the assembly without a fitted pressure gauge.
Air routing strictly follows filter, regulator and lubricator stages, so oil mist is introduced downstream of the regulator seat. Condensate accumulates in a 100 cc bowl and lubricant in a 185 cc reservoir, dictating the maintenance interval. The reverse-flow (reflux) valve is fitted, appearing as a separate pneumatic symbol in the catalogue.

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 GAC400N10SNWK Is Used
Automotive Assembly Lines
Feeds multiple pneumatic presses and actuators on a car manufacturing line, relying on the 5 um element to protect precision valves from fine particulates.
Carton Sealing Machines
Conditions air for continuous packaging conveyors where the 100 cc condensate bowl and semi-auto drain handle moisture from high-cycle actuator duty.
Lab Test Equipment Rigs
Supplies regulated, oil-misted air to instrument panels, requiring the operator to add a gauge to the 1/4in connection to verify the 0.15-0.9 MPa setpoint.
Is the Airtac GAC F.R.L. Unit GAC400N10SNWK the Right Air-Prep Unit?
Choose this 3/8in body for mid-capacity duties, stepping up from the GAC300 which offers a 3000 L/min plotted flow envelope at 0.7 MPa inlet versus the 6000 L/min curve of this GAC400. The nylon bowl keeps the standard 1.0 MPa (145 psi) maximum and -5 to 70 C temperature limits, requiring chemical compatibility confirmation for aggressive surroundings. Since no gauge is supplied, the set pressure cannot be read without adding one to the 1/4in gauge connection. If the downstream line must stay oil-free, omit the lubricator and choose a filter-regulator instead. Replacement spares share the 400-10 suffix: GAF400-10, GAR400-10 and GAL400-10. Stepping from the GAC300 to this GAC400 doubles the flow envelope, providing exactly a 2x sizing multiplier at 0.7 MPa inlet.
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 GAC400N10SNWK FAQ
This standard type 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 from -5 to 70 C, weighs 2390 g, holds 100 cc of condensate and 185 cc of oil, and uses ISO VG 32 lubricant.
The N in the ordering code signifies no gauge is supplied. The unit features a 1/4in gauge connection, allowing operators to install a separate PT-threaded gauge reading MPa/psi to monitor the 5 um filtered output.
