Airtac GAC F.R.L. Unit GAC500C20SWK
The AirTAC Airtac GAC F.R.L. Unit GAC500C20SWK 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 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC500C20SWK
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this GAC500C20SWK combines a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port pairs with a 2460 g mass, placing it firmly in a heavy-duty size class that requires a solid panel or frame mount rather than tubing support. Air passes through the filter first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls.
This specific configuration uses a 5 um element to trap far finer particles than the standard grade, making it ideal for precision valves or instrument air at the cost of more frequent element service. The metal bowl equips the unit for rugged environments, and the circular gauge reads MPa/psi for the default PT thread. A reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue.

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 GAC500C20SWK Is Used
Automotive Assembly Lines
Feeds large multi-station headers in vehicle manufacturing, where the 5 um element protects robotic actuators from fine particulate ingress.
Heavy Palletizing Cells
Conditions air for high-force grippers and heavy-duty pushers, relying on the 108 cc drain bowl to capture condensate during long production runs.
CNC Machine Tooling
Supplies precisely regulated air to pneumatic clamps and tool changers, utilizing the 225 cc oil bowl to maintain consistent downstream lubrication.
Is the Airtac GAC F.R.L. Unit GAC500C20SWK the Right Air-Prep Unit?
Choose this 3/4in body for substantial air flows, noting the catalogue flow curve for the GAC500 is plotted to 7000 L/min at 0.7 MPa inlet, compared to the GAC600 which extends to 12000 L/min. The metal bowl suits harsher industrial settings, while the semi-auto and manual drain pair gives operators flexible condensate management. Because the lubricator introduces oil mist downstream, select a separate filter-regulator if your line must remain strictly oil-free. Spares follow the 500-20 suffix exactly: GAF500-20, GAR500-20 and GAL500-20. Stepping up to the GAC600 yields roughly 1.7x the flow envelope of this 7000 L/min capacity.
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 GAC500C20SWK 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 between -5 to 70 C, features a 108 cc drain bowl and a 225 cc oil bowl, weighs 2460 g, and uses ISO VG 32 lubricant.
The K indicates that a reverse-flow (reflux) valve is attached to the unit. The catalogue displays this as a distinct pneumatic symbol on its own page, and the specific functional details should be confirmed from that datasheet.
