Airtac GAC F.R.L. Unit GAC500N20ALNW
The AirTAC Airtac GAC F.R.L. Unit GAC500N20ALNW 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 GAC500N20ALNW
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port serves heavy-duty circuits, while the 5 um element captures fine particulates before they reach precision valves. Because the lubricator sits last in the airflow path, oil mist is introduced downstream of the regulator seat, preventing fouling.
The nylon bowl equips this unit for specific environmental considerations, and the automatic drain clears condensate from the 108 cc sump without operator intervention. Operating at the lower pressure range of 0.15-0.4 MPa (20-58 psi), it targets sensitive instrumentation. No gauge is supplied, but a 1/4in connection allows adding one 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 GAC500N20ALNW Is Used
Laboratory Pneumatic Rails
Feeds low-pressure air to sensitive analytical instruments and glassware actuators where a 0.4 MPa ceiling prevents accidental overpressurization.
Pharmaceutical Capping Lines
Supplies steady, finely filtered 5 um air to capping heads and indexing gates that handle delicate vials without particulate contamination.
Textile Spinning Frames
Conditions air for low-tension yarn guides and small cylinders, adding necessary oil mist to protect high-speed moving bushings.
Is the Airtac GAC F.R.L. Unit GAC500N20ALNW the Right Air-Prep Unit?
Choose this 2460 g assembly when a large-flow line requires sensitive pressure control rather than the standard 0.15-0.9 MPa range. The catalogue flow curve for the GAC500 is plotted to 7000 L/min at 0.7 MPa inlet, offering a substantial sizing envelope for multi-actuator manifolds. If the machinery requires completely oil-free downstream air, omit the lubricator and select a dedicated filter-regulator instead. For maintenance, the individual elements correspond to GAF500-20, GAR500-20 and GAL500-20.
The lower-pressure type tops out at 0.4 MPa, which is 44% of the Standard type's 0.9 MPa ceiling, so verify your actuators never require higher force before specifying this variant.
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 GAC500N20ALNW FAQ
This model 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. It features a 108 cc drain bowl, a 225 cc oil bowl, and weighs 2460 g. The recommended lubricant is ISO VG 32.
The N in the model code indicates no gauge is supplied from the factory, though a 1/4in gauge connection is available if you need to add one later. The W code signifies a 5 um element, which traps much finer particles than the standard 40 um filter, making it ideal for precision pneumatic logic.
