Airtac GAC F.R.L. Unit GAC500C20SN
The AirTAC Airtac GAC F.R.L. Unit GAC500C20SN 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 3/4" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC500C20SN
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this GAC500C20SN unit combines a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port serves high-demand circuits, while the standard pressure range operates from 0.15-0.9 MPa (20-130 psi). A 40 um element captures solid particulates, and the robust metal bowl equips this assembly for rugged industrial environments.
Air passes through the filter, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls. Because no gauge is supplied, operators must use the 1/4in gauge connection to add instrumentation if they need to read the set pressure. Weighing 2460 g, this 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 GAC500C20SN Is Used
Automotive Assembly Lines
Feeds main air headers for multi-station robotic welding cells where a steady 3/4in supply and substantial flow are required to keep heavy actuators cycling.
Corrugated Box Plants
Conditions air for large format corrugated converting machinery, relying on the metal bowl to withstand the physical demands of the production floor.
Material Handling Systems
Supplies pneumatic diverters and heavy-duty sortation gates on high-throughput distribution conveyors that depend on consistent lubricated air.
Is the Airtac GAC F.R.L. Unit GAC500C20SN the Right Air-Prep Unit?
Choose this 3/4in body when a machine header demands substantial air volume, stepping up from the GAC400 which plots to 6000 L/min at 0.7 MPa inlet versus the 7000 L/min envelope of this GAC500. The metal bowl suits harsher surroundings where standard PC might not be preferred, and the semi-auto plus manual drain pair gives operators dual control over the 108 cc condensate sump. If the downstream line must remain oil-free, select a filter-regulator instead because this lubricator intentionally adds oil mist.
Replacement spares follow the 500-20 suffix exactly: order GAF500-20, GAR500-20 and GAL500-20 to service the individual units. Stepping to this body from a GAC200 increases the oil capacity from 36 cc to 225 cc, yielding a 6.25x ratio in lubricant volume that drastically reduces maintenance interventions.
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 GAC500C20SN 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, weighs 2460 g, features a 108 cc drain bowl and a 225 cc oil bowl, and requires ISO VG 32 lubricant.
The N in the product code indicates no gauge is supplied from the factory. The unit has a 1/4in gauge connection, allowing you to install a specific PT-thread gauge reading in MPa/psi to match your operators' monitoring preferences.
