Airtac GAC F.R.L. Unit GAC400N10ALNW
The AirTAC Airtac GAC F.R.L. Unit GAC400N10ALNW 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 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC400N10ALNW
Delivering cleaned, regulated and lubricated air for downstream pneumatics, this GAC400 unit combines a filter, regulator and lubricator on a single L-shape bracket. The 3/8in port serves a 2390 g assembly that uses a 5 um element to trap fine particles before the 0.15-0.4 MPa (20-58 psi) lower-pressure range is set. A nylon bowl houses the automatic drain, which empties the 100 cc condensate sump without operator input.
Because the lubricator sits last in the sequence, oil mist is injected downstream of the regulator seat, preventing fouling of the internal pressure-control mechanism. No gauge is supplied, but the body features a 1/4in gauge connection if visual monitoring is added later. Spares follow the 400-10 suffix: GAF400-10, GAR400-10 and GAL400-10.

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 GAC400N10ALNW Is Used
Laboratory Gas Panels
Feeds low-pressure actuation and handling systems where a strict 0.15-0.4 MPa ceiling protects sensitive glassware and delicate instruments.
Precision Valve Banks
The 5 um element safeguards micro-solenoid and proportional valve nozzles from particulate ingress in fine-tolerance assembly jigs.
Light-Clamp Packaging Lines
Provides steady low-force actuation for sealing and capping heads, with the automatic drain handling condensate during continuous shifts.
Is the Airtac GAC F.R.L. Unit GAC400N10ALNW the Right Air-Prep Unit?
Choose this lower-pressure L-type assembly for machines operating strictly under 0.4 MPa; if the application may ever require higher force, the standard S-type is the correct choice. The 5 um W-grade element suits precision valves and instrument air, trading finer filtration for more frequent element service compared to the 40 um default. The automatic drain clears condensate from the 100 cc bowl unattended, a decisive feature for wet lines or remote installations. If the downstream line must remain oil-free, omit the lubricator and select a filter-regulator instead. The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, providing a sizing envelope that is double the 3000 L/min envelope of the GAC300. Keep in mind that 0.4 MPa is 44% of the standard 0.9 MPa ceiling.
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 GAC400N10ALNW FAQ
This lower-pressure unit regulates from 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, weighs 2390 g, features a 100 cc drain bowl and a 185 cc oil bowl, and uses ISO VG 32 lubricant.
The N in the ordering code indicates no gauge is supplied. The body has a 1/4in gauge connection machined in, allowing operators to install a compatible MPa/psi PT-thread gauge later to visually verify the 0.15-0.4 MPa setpoint.
