Airtac GAC F.R.L. Unit GAC500C20ASNWK
The AirTAC Airtac GAC F.R.L. Unit GAC500C20ASNWK 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 GAC500C20ASNWK
Delivering cleaned, regulated and lubricated air for heavy pneumatic duty, this GAC500C20ASNWK combines a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. The 3/4in port serves as the inlet for a standard type system operating within 0.15-0.9 MPa (20-130 psi). A 5 um element captures fine particulates before the air reaches the regulator, while the automatic drain empties the 108 cc condensate bowl without operator intervention.
Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling. Weighing 2460 g, this assembly requires a rigid frame or panel mount rather than tubing support. The metal bowl equips this unit for demanding industrial settings, and no gauge is supplied, though a 1/4in connection is provided if you need to add instrumentation later.

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 GAC500C20ASNWK Is Used
Automotive Assembly Line
Feeds a multi-station manufacturing cell where the 3/4in port and 5 um filtration protect sensitive robotic actuators from fine particulates.
Palletizing Equipment
Conditions air for heavy-duty bagging and palletizing machinery, with the automatic drain handling high condensate loads during continuous shifts.
CNC Machining Centers
Supplies lubricated air to large pneumatic clamps and tool changers, utilizing the 108 cc drain bowl to capture moisture in high-volume environments.
Is the Airtac GAC F.R.L. Unit GAC500C20ASNWK the Right Air-Prep Unit?
This assembly is built for substantial air flows, with the catalogue flow curve plotted to 7000 L/min at 0.7 MPa inlet, making it a strong candidate for multi-station machine headers. Stepping down to a GAC400 drops that plotted envelope to 6000 L/min, whereas moving up to a GAC600 extends it to 12000 L/min. The 5 um element offers superior protection for precision valves compared to the standard 40 um grade, though it will require more frequent replacement. The automatic drain clears condensate autonomously, a critical feature for unattended or wet lines. If your downstream process requires strictly oil-free air, you must omit the lubricator and choose a filter-regulator instead. The reverse-flow (reflux) valve is fitted on this model, shown as a separate pneumatic symbol in the catalogue. For maintenance, order GAF500-20, GAR500-20 and GAL500-20 spares. The 1.5 MPa proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, but this is not permission to run above 1.0 MPa.
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 GAC500C20ASNWK FAQ
This standard type unit regulates air 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 in temperatures from -5 to 70 C, weighs 2460 g, and features a 108 cc condensate bowl alongside a 225 cc oil bowl. The recommended lubricant is ISO VG 32.
The N in the product code indicates no gauge is supplied, but the body features a 1/4in gauge connection so you can install one to monitor your 0.15-0.9 MPa operating range. The K code means a reverse-flow (reflux) valve is fitted, which the catalogue details as a separate pneumatic symbol on its own page.
