About the Airtac GAC F.R.L. Unit GAC50020ASNWK
Delivering cleaned, regulated and lubricated air for demanding pneumatics, this AirTAC GAC50020ASNWK combines 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 the pressure-control mechanism.
This configuration uses a PC bowl and ships without a gauge, leaving the 1/4in gauge connection open for a user-supplied instrument. The automatic drain clears condensate from the 108 cc sump without operator intervention. A reverse-flow (reflux) valve is fitted, which the catalogue depicts as a separate pneumatic symbol with details on its own page. The assembly weighs 2460 g and operates from -5 to 70 C using ISO VG 32 lubricant.

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 GAC50020ASNWK Is Used
Automotive Assembly Lines
Feeds multi-station robotic welding cells where the 3/4in port sustains high actuator cycling and the automatic drain handles heavy condensate loads continuously.
High-Speed Cartoning
Conditions air for continuous motion packaging machines, ensuring the 5 um element protects precision flow controls from particulate ingress during extended runs.
Metal Stamping Presses
Supplies regulated, lubricated air to large pneumatic clutches and brakes, relying on the 108 cc drain bowl to capture moisture in heavy-duty industrial environments.
Is the Airtac GAC F.R.L. Unit GAC50020ASNWK the Right Air-Prep Unit?
Choose this 2460 g assembly for substantial air flows where manual condensate draining is impractical; the automatic drain empties the 108 cc bowl independently, whereas a blank-drain GAC500 requires manual or semi-auto intervention. The 5 um element suits precision instrumentation but requires more frequent replacement than the standard 40 um filter, and the separate spares are GAF500-20, GAR500-20 and GAL500-20. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. Stepping down to a GAC400 reduces the plotted flow envelope from 7000 L/min to 6000 L/min at 0.7 MPa inlet, whereas moving up to a GAC600 increases it to 12000 L/min. The 1.5 MPa (215 psi) proof pressure provides a 1.5x burst-test margin over the 1.0 MPa (145 psi) 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 GAC50020ASNWK FAQ
This model operates at 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). The temperature range is -5 to 70 C, the filtering grade is 5 um, and the recommended lubricant is ISO VG 32. It features a 108 cc drain bowl, a 225 cc oil bowl, and weighs 2460 g.
The N in the ordering code indicates no gauge is supplied. The unit has a 1/4in gauge connection, allowing operators to install a specific instrument reading in MPa or psi that matches their local standards. The set pressure cannot be read until a gauge is added to this port.
