About the Airtac GAC F.R.L. Unit GAC500N20ALW
Delivering cleaned, regulated and lubricated air for demanding pneumatics, this GAC500 unit integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port pairs with a 2460 g mass, requiring a solid frame mount rather than tubing support. Air passes through the 5 um element before the regulator, ensuring the internal seat stays free of oil mist introduced downstream by the lubricator.
Configured for low-pressure duties, the regulator operates within 0.15-0.4 MPa (20-58 psi). The nylon bowl holds 108 cc of condensate and 225 cc of oil, with an automatic drain fitted to clear water without an operator. A circular gauge reads MPa/psi for the default PT thread, allowing direct visual confirmation of the set pressure.

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 GAC500N20ALW Is Used
Textile Machinery
Feeds low-pressure air to looms and spinning frames where delicate yarn handling requires a 0.4 MPa ceiling and fine 5 um filtration.
Carton Sealing Lines
Conditions air for automated folder-sealers, using the 225 cc oil bowl to maintain steady lubrication for high-speed moving jaws.
Pneumatic Sorting
Supplies 3/4in main air to distribution manifolds for package diverters, relying on the automatic drain for wet environments.
Is the Airtac GAC F.R.L. Unit GAC500N20ALW the Right Air-Prep Unit?
Choose this assembly for 3/4in lines needing fine 5 um filtration and low-pressure control. The automatic drain suits unattended stations, while the nylon bowl matches standard -5 to 70 C environments. If the machine requires oil-free output, omit the lubricator and select a filter-regulator instead. Replacement parts share the 500-20 suffix: GAF500-20, GAR500-20 and GAL500-20. Stepping up to the GAC600 body shifts the plotted flow envelope from 7000 L/min to 12000 L/min at 0.7 MPa inlet, an increase of roughly 1.7x.
Quick checklist
- ✓ Body size for your peak flow (3/4" 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 108 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 2460 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 GAC500N20ALW FAQ
It operates at 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). Temperature range is -5 to 70 C. The unit weighs 2460 g, features a 108 cc drain bowl and a 225 cc oil bowl, and uses ISO VG 32 lubricant.
The 5 um element traps finer particles than the standard 40 um grade, protecting precision valves. The lower pressure type restricts output to 0.4 MPa, which is about 44% of the standard 0.9 MPa ceiling, preventing over-pressurization in sensitive actuators.
