Airtac GAC F.R.L. Unit GAC500C20ALNK
The AirTAC Airtac GAC F.R.L. Unit GAC500C20ALNK 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 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC500C20ALNK
Delivering cleaned, regulated and lubricated air for heavy pneumatic lines, this AirTAC F.R.L. combination pairs a 3/4in port with a robust metal bowl. The assembly integrates a filter, regulator and lubricator on a single L-shape bracket, eliminating inter-unit tubing and ensuring oil mist is introduced downstream of the regulator seat. Outfitted with a 40 um element, it processes air within a lower pressure range of 0.15-0.4 MPa (20-58 psi).
Weighing 2460 g, the unit requires a firm panel or frame mount rather than tubing support. The automatic drain clears condensate from the 108 cc bowl without operator intervention, which suits unattended stations. A reverse-flow (reflux) valve is fitted, shown in the catalogue as a separate pneumatic symbol. No gauge is supplied, but a 1/4in connection allows adding one to monitor the set pressure.

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 GAC500C20ALNK Is Used
Textile Machinery Headers
Feeds low-pressure air across large weaving looms where delicate fibers require consistent, oil-misted actuation below 0.4 MPa.
Packaging Line Diverters
Conditions air for high-speed sorting cylinders, using the automatic drain to handle condensate during continuous daily shifts.
Woodworking Sanders
Supplies regulated air to pneumatic sanding heads, preventing over-pressurization while maintaining steady lubrication for moving parts.
Is the Airtac GAC F.R.L. Unit GAC500C20ALNK the Right Air-Prep Unit?
Choose this lower-pressure type for circuits capped at 0.4 MPa; if the machinery might ever demand more, select the standard type instead. The 40 um element balances standard particulate trapping with longer service intervals compared to the 5 um option. Because the lubricator adds oil mist downstream, choose a filter-regulator if the application requires strictly oil-free air. Thread options cover PT, G and NPT, with the default PT scale reading MPa/psi. Should a component fail, order the matching GAF500-20, GAR500-20 and GAL500-20 spares. Stepping down to the GAC400 halves the flow envelope to 6000 L/min versus this body's 7000 L/min plotted curve at 0.7 MPa inlet. The 0.4 MPa ceiling is 44% of the standard 0.9 MPa maximum.
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 GAC500C20ALNK FAQ
This lower-pressure unit 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). It features a 3/4in port, a 40 um element, and a temperature range of -5 to 70 C. The drain bowl holds 108 cc and the oil bowl 225 cc. Weighing 2460 g, it uses ISO VG 32 lubricant.
The N in the model code indicates no gauge is supplied. The body features a 1/4in gauge connection, allowing operators to install a separate gauge reading MPa/psi for the default PT thread to verify the downstream set pressure.
