Airtac GAC F.R.L. Unit GAC500C20ALNW
The AirTAC Airtac GAC F.R.L. Unit GAC500C20ALNW 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 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC500C20ALNW
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC GAC500C20ALNW F.R.L. combination integrates 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 sensitive valves. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of internal components.
Built with a robust metal bowl and an automatic drain, this 2460 g unit clears condensate without operator intervention and holds 108 cc of liquid and 225 cc of oil. The lower-pressure type restricts the operating range to 0.15-0.4 MPa (20-58 psi). No gauge is supplied, but the body features a 1/4in gauge connection for adding instrumentation if visual pressure monitoring becomes necessary.

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 GAC500C20ALNW Is Used
Heavy Machinery Headers
Feeds a main distribution header for large-scale automated presses, ensuring consistent low-pressure air reaches multiple downstream actuators.
High-Speed Packaging Lines
Supplies finely filtered, lubricated air to continuous motion packaging equipment where the 5 um element protects precision gating valves.
Material Handling Systems
Conditions air for heavy-duty conveyor belt drives and diverters, relying on the 225 cc oil bowl to extend maintenance intervals.
Is the Airtac GAC F.R.L. Unit GAC500C20ALNW the Right Air-Prep Unit?
Choose this metal-bowl configuration for harsher industrial environments where solvents or impact risks make standard PC bowls unsuitable. The automatic drain is decisive for unattended or wet lines, as it dumps condensate on demand without manual intervention. If your downstream process requires strictly oil-free air, you must omit the lubricator and select a dedicated filter-regulator instead of this combination unit. For maintenance, the assembly breaks down into separately orderable spares sharing the exact same body and port: 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, offering a substantial sizing envelope compared to the 3000 L/min limit of the GAC300. However, the lower-pressure type caps the ceiling at 0.4 MPa, which is 44% of the 0.9 MPa maximum available on the standard type.
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 GAC500C20ALNW FAQ
This lower-pressure type operates at 0.15-0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It features a 3/4in port, a 108 cc drain bowl, a 225 cc oil bowl, and weighs 2460 g.
The N in the product code indicates no gauge is supplied. The body incorporates a 1/4in gauge connection, allowing you to install a separate pressure measuring device if your operators need to visually confirm the downstream setting.
