Airtac GAC F.R.L. Unit GAC500N20SNW
The AirTAC Airtac GAC F.R.L. Unit GAC500N20SNW 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 GAC500N20SNW
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this GAC500N20SNW combines a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port serves high-flow duties, while the 5 um element captures fine particulates before they reach sensitive valves. Because the lubricator sits last in the sequence, oil mist enters the downstream line without fouling the regulator seat.
Weighing 2460 g, this unit relies on a solid panel mount rather than tubing support. The nylon bowl handles standard 1.0 MPa max pressure across the -5 to 70 C range. No gauge is supplied, but a 1/4in connection allows adding one to verify the 0.15-0.9 MPa (20-130 psi) operating band.

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 GAC500N20SNW Is Used
Automotive Assembly Lines
Feeds large robotic welding arms and body framing actuators where a 3/4in supply line maintains adequate pressure under simultaneous cylinder firing.
Palletizer Tooling
Conditions air for heavy-duty vacuum chuck arrays and bagging clamps, with the 5 um element protecting tight-tolerance venturi nozzles from grit.
CNC Machine Tooling
Supplies clean, lubricated air to multi-station machining centers for tool changers and air-blast clearing, relying on the 225 cc oil bowl for extended shifts.
Is the Airtac GAC F.R.L. Unit GAC500N20SNW the Right Air-Prep Unit?
Choose this 3/4in body for substantial air requirements, stepping up from the GAC400 which plots to 6000 L/min at 0.7 MPa inlet versus this body's 7000 L/min envelope. The 5 um element suits instrument air or precision pneumatics, trading off a higher restriction for finer filtration than the 40 um standard. If your process requires strictly oil-free delivery, omit the lubricator and select a filter-regulator instead.
The semi-auto and manual drains pair with a 108 cc condensate sump and a 225 cc oil reservoir, dictating the maintenance rhythm. Replacement spares follow the body-port suffix exactly: GAF500-20, GAR500-20 and GAL500-20. Stepping to this size from the GAC400 yields a 1.17x increase in plotted flow envelope (6000 to 7000 L/min at 0.7 MPa inlet).
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 GAC500N20SNW FAQ
This standard type 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. It features a 108 cc drain bowl, a 225 cc oil bowl, weighs 2460 g, and uses ISO VG 32 or equivalent lubricant.
The N in the ordering code indicates no gauge is supplied from the factory. The body features a 1/4in gauge connection, allowing you to install a compatible PT-thread gauge reading in MPa/psi to monitor your specific 0.15-0.9 MPa setpoint.
