About the Airtac GAC F.R.L. Unit GAC400N15L
Delivering cleaned, regulated and lubricated air for pneumatic machinery, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. It features a 1/2in port, a 40 um element and a lower pressure range of 0.15-0.4 MPa (20-58 psi). The internal flow path sequences water separation first, pressure setting second and oil mist last, ensuring the regulator seat stays clean.
This model carries a nylon bowl and a fitted circular gauge reading MPa/psi for the default PT thread. Weighing 2390 g, the assembly includes a 100 cc condensate bowl and a 185 cc oil reservoir. The semi-auto and manual drain pair is fitted, dumping condensate on pressure drops or on demand.

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 GAC400N15L Is Used
Textile Machinery
Feeds low-pressure air to looms and spinning frames where delicate yarn handling requires stable, regulated pressure up to 0.4 MPa.
Carton Erectors
Conditions air for pneumatic folding arms and suction cups on packaging lines, utilizing the 185 cc oil bowl for prolonged actuator life.
Lab Automation
Supplies precisely regulated, lubricated air to sensitive test fixtures and small cylinders operating well below standard industrial pressures.
Is the Airtac GAC F.R.L. Unit GAC400N15L the Right Air-Prep Unit?
Choose this GAC400 body for medium-scale duties requiring a 1/2in port, noting its catalogue flow curve is plotted to 6000 L/min at 0.7 MPa inlet. The nylon bowl offers an alternative to the standard PC or metal options, sharing the exact same 1.0 MPa max pressure and -5 to 70 C thermal limits. Because this is an L type, the outlet pressure tops out at 0.4 MPa; if the machine might ever need more, the S type is the correct choice. Remember that oil mist is added downstream, so select a separate filter-regulator if the line must remain oil-free. Should the element clog, order the GAF400-15, GAR400-15 and GAL400-15 spares. The 0.4 MPa ceiling is 44% of the Standard type's 0.9 MPa maximum.
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 GAC400N15L 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, uses ISO VG 32 lubricant, and features a 100 cc drain bowl with a 185 cc oil bowl.
The L type restricts the regulating range to 0.15-0.4 MPa (20-58 psi), making it unsuitable for systems requiring higher actuator force. The nylon bowl provides a different material build compared to the standard PC or metal bowls, while retaining the same 1.0 MPa maximum pressure rating.
