Airtac GAC F.R.L. Unit GAC500N20AS
The AirTAC Airtac GAC F.R.L. Unit GAC500N20AS 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 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC500N20AS
Delivering cleaned, regulated and lubricated air for demanding pneumatic lines, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port pairs with a 2460 g mass, placing it firmly in a heavy-duty size class that requires a solid panel or frame mount rather than tubing support. Air passes through the 40 um element first, then the regulator, before oil mist is introduced downstream so the regulator seat never fouls.
The nylon bowl equips this unit for environments where material compatibility is prioritized, operating within the standard 0.15-0.9 MPa (20-130 psi) range. An automatic drain clears condensate from the 108 cc bowl without an operator, a decisive feature for unattended machinery. A circular gauge is fitted, reading MPa/psi for the default PT thread, allowing operators to verify the set pressure directly at the unit.

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 GAC500N20AS Is Used
Automotive Assembly Line
Feeds a multi-station machine header where the 3/4in port and automatic drain sustain high air consumption without requiring manual condensate intervention during shifts.
Palletizing Robots
Conditions air for heavy-duty grippers and actuators, relying on the 225 cc oil bowl to maintain a steady lubricant supply for continuous end-of-arm tooling movements.
CNC Machining Centers
Prepares drive air for large pneumatic clamps and tool changers, using the 40 um element to protect precision valves from particulate ingress.
Is the Airtac GAC F.R.L. Unit GAC500N20AS the Right Air-Prep Unit?
Choose this 3/4in body when a machine header demands a high flow capacity, noting the catalogue flow curve for the GAC500 is plotted to 7000 L/min at 0.7 MPa inlet. Stepping down to the GAC400 drops that envelope to 6000 L/min, whereas moving up to the GAC600 extends it to 12000 L/min. The 108 cc condensate bowl and 225 cc oil bowl dictate the service frequency; this assembly is attended far less often than a smaller body. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. The three units are separately orderable as GAF500-20, GAR500-20 and GAL500-20, so a damaged bowl does not require replacing the whole assembly. The 1.5 MPa (215 psi) proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, which is a safety rating rather than 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 GAC500N20AS FAQ
The standard type operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It handles temperatures from -5 to 70 C using ISO VG 32 lubricant. The unit weighs 2460 g, features a 108 cc drain bowl and a 225 cc oil bowl, and uses a 40 um element.
The A in the ordering code specifies an automatic drain that expels condensate from the 108 cc bowl without operator intervention, making it ideal for wet lines or unattended installations. The nylon bowl material shares the exact same 1.0 MPa pressure and -5 to 70 C temperature limits as the metal and PC options, so buyers should confirm chemical compatibility for aggressive surroundings.
