About the Airtac GAC F.R.L. Unit GAC50020AS
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, the AirTAC GAC50020AS is a three-unit F.R.L. combination built around a 3/4in port. The standard pressure type governs output between 0.15-0.9 MPa (20-130 psi), while the 40 um filter element captures solid contaminants before they reach downstream valves. A circular gauge is fitted, reading MPa/psi for the default PT thread.
Weighing 2460 g, this assembly integrates a filter, regulator and lubricator on a single L-shape bracket using quick mounting clamps. The automatic drain actively clears condensate from the 108 cc bowl without operator intervention, which is decisive for unattended or wet lines. Air passes through the filter, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls.

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 GAC50020AS Is Used
Automotive Assembly Line
Feeds a multi-station machine header where the 3/4in port and 7000 L/min flow envelope sustain high air demand for concurrent pneumatic wrenches and actuators.
Palletizing Cell
Conditions air for heavy-duty grippers and large-bore cylinders, with the automatic drain clearing condensate during continuous unattended shift operations.
CNC Machine Tool Air
Supplies cleaned and lubricated air at a stable 0.15-0.9 MPa (20-130 psi) to tool changers and clamping fixtures, protecting precision moving parts.
Is the Airtac GAC F.R.L. Unit GAC50020AS the Right Air-Prep Unit?
Choose this 3/4in body when a machine header requires a robust supply, stepping up from the GAC400 which offers a plotted flow envelope of 6000 L/min at 0.7 MPa inlet versus the 7000 L/min envelope of this GAC500. The PC bowl handles standard 1.0 MPa (145 psi) max pressures, and the 225 cc oil bowl extends the interval between manual top-ups. If the downstream line must stay oil-free, omit the lubricator and choose a filter-regulator instead. Should a component fail, order the GAF500-20, GAR500-20 and GAL500-20 spares individually. Stepping up from the GAC400 to this GAC500 yields roughly a 1.17x increase in the plotted flow envelope.
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 GAC50020AS FAQ
This 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). 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 lubricant.
The A in the ordering code denotes an automatic drain fitted to the PC bowl. It expels condensate automatically without an operator, making the unit highly suitable for wet lines or remote installations where manual draining is impractical.
