About the Airtac GAC F.R.L. Unit GAC500C20ASW
Delivering cleaned, regulated and lubricated air for heavy pneumatic lines, this GAC500C20ASW combines a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port serves high-demand circuits, while the 5 um element captures fine particulates before they reach precision valves. A metal bowl houses the 108 cc condensate sump and 225 cc oil reservoir.
Air routes through the filter first, then the regulator, ensuring oil mist is added downstream so the regulating seat never fouls. The automatic drain empties condensate without an operator, and the fitted circular gauge reads MPa/psi for the default PT thread. Max pressure is 1.0 MPa (145 psi) over a -5 to 70 C range, using ISO VG 32 oil.

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 GAC500C20ASW Is Used
Automotive Assembly Lines
Feeds large robotic welding arms and body panel stamping presses that consume high air volumes through 3/4in headers.
Palletizing Stations
Supplies stable pressure and fine 5 um filtration to heavy-duty pneumatic grippers and lift cylinders on automated palletizers.
CNC Machine Tooling
Protects precision air bearings and tool changers by removing fine particulates while adding necessary oil mist downstream.
Is the Airtac GAC F.R.L. Unit GAC500C20ASW the Right Air-Prep Unit?
Choose this 2460 g assembly for substantial air flows where panel or frame mounting is required rather than tubing support. The 5 um element provides finer protection than the 40 um standard, demanding more frequent element changes to protect downstream instruments. The metal bowl suits harsher industrial settings compared to PC or nylon alternatives. If the application requires completely dry air without oil mist, omit the lubricator and select a standalone filter-regulator. Replacement spares are GAF500-20, GAR500-20 and GAL500-20. The catalogue flow curve for the GAC500 is plotted to 7000 L/min at 0.7 MPa inlet, which is roughly 1.17x the 6000 L/min envelope of the GAC400.
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 GAC500C20ASW FAQ
This standard type unit operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It features a 3/4in port, a 5 um element, an automatic drain, a 108 cc drain bowl capacity, a 225 cc oil bowl capacity, and weighs 2460 g. The operating temperature is -5 to 70 C using ISO VG 32 lubricant.
The 5 um W element catches far finer particles than the 40 um standard, making it ideal for sensitive valves but requiring more frequent replacement. The automatic drain clears the 108 cc condensate sump without operator intervention, which is decisive for unattended or wet lines.
