About the Airtac GAC F.R.L. Unit GAC500N20SW
Delivering cleaned, pressure-set and oil-misted air for demanding pneumatics, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port serves mid-to-large flow requirements, while the standard pressure range operates from 0.15-0.9 MPa (20-130 psi). A 5 um element captures fine particulates to protect precision valves, and a circular gauge reading MPa/psi is fitted for the default PT thread.
The nylon bowl equips this assembly for environments where chemical resistance is prioritized, sharing the same 1.0 MPa (145 psi) maximum pressure and -5 to 70 C thermal limits as other bowl materials. Condensate is managed by a semi-auto and manual drain pair, with the 108 cc drain bowl and 225 cc oil reservoir dictating the maintenance rhythm. Weighing 2460 g, the assembly requires a solid panel or frame mount rather than tubing support.

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 GAC500N20SW Is Used
Automotive Assembly Lines
Feeds main air headers for multi-station welding cells where a 3/4in port sust high flow to several actuators simultaneously.
Palletizing Robots
Conditions air for heavy-duty end effectors and grippers, relying on the 5 um element to protect sensitive robotic valve manifolds.
Textile Machinery
Supplies looms and spinning frames requiring continuous oil mist for high-speed moving parts, utilizing the 225 cc oil reservoir.
Is the Airtac GAC F.R.L. Unit GAC500N20SW the Right Air-Prep Unit?
Choose this configuration when a 5 um element is required for sensitive instrumentation, accepting the trade-off of more frequent element service compared to the standard 40 um grade. The semi-auto and manual drain setup dumps condensate on every pressure drop or on operator demand, contrasting with the automatic drain option suited for unattended lines. If the downstream circuit must remain free of fluid, omit the lubricator and select a dedicated filter-regulator instead. For maintenance, the assembly accepts individual GAF500-20, GAR500-20 and GAL500-20 replacement units. Stepping up from the GAC400 body increases the plotted flow envelope from 6000 to 7000 L/min at 0.7 MPa inlet, a 1.17x capacity gain for high-demand circuits.
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 GAC500N20SW FAQ
This standard type unit regulates from 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 operates from -5 to 70 C, features a 5 um element, and includes a 108 cc drain bowl alongside a 225 cc oil bowl. The assembly weighs 2460 g and uses ISO VG 32 lubricant.
It uses a nylon bowl and is fitted with both a semi-auto and a manual drain. The semi-auto mechanism expels condensate during each pressure drop, while the manual drain allows on-demand evacuation, giving operators direct control over the 108 cc reservoir.
