About the Airtac GAC F.R.L. Unit GAC500N20ALWK
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. The 3/4in port serves heavy-duty circuits, while the 5 um element captures fine particulates before they reach precision valves. A circular gauge is fitted, reading MPa/psi for the default PT thread, so operators can visually confirm the set pressure.
Air passes through the filter first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls. This lower-pressure type restricts output to 0.15-0.4 MPa (20-58 psi), making it unsuitable for any machine that might later require higher actuation force. The nylon bowl holds 108 cc of condensate and 225 cc of oil, and the automatic drain clears liquid without an operator present.

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 GAC500N20ALWK Is Used
Low-Force Assembly Lines
Feeds large-bore cylinders operating at safe, reduced pressures for clamping delicate components during automotive component assembly.
Pneumatic Conveying Inlets
Conditions air for diverters and gate valves in bulk powder handling, where the 5 um element protects seals from abrasive dust.
Textile Machinery Headers
Supplies a regulated 0.4 MPa ceiling to multi-station looms, ensuring consistent yarn tension without overstressing delicate guide mechanisms.
Is the Airtac GAC F.R.L. Unit GAC500N20ALWK the Right Air-Prep Unit?
Choose this 2460 g assembly when a large-scale line needs low-pressure actuation, as its 3/4in port handles substantial flow. The catalogue flow curve for the GAC500 is plotted to 7000 L/min at 0.7 MPa inlet, offering a sizing envelope that is roughly 17% larger than the 6000 L/min envelope of the GAC400. If the application must remain strictly oil-free, omit the lubricator and choose a separate filter-regulator instead. The reverse-flow (reflux) valve is fitted on this model, which the catalogue shows as a separate pneumatic symbol with details on its own page. Replacement spares share the exact same body and port suffix: GAF500-20, GAR500-20 and GAL500-20. Because the lower-pressure type tops out at 0.4 MPa, it offers only 44% of the standard 0.9 MPa ceiling.
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 GAC500N20ALWK FAQ
This unit regulates air from 0.15-0.4 MPa (20-58 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, uses a 108 cc drain bowl and a 225 cc oil bowl, and weighs 2460 g. The recommended lubricant is ISO VG 32 or equivalent.
The 5 um element traps far finer particles than the standard 40 um grade, making it ideal for precision instrument air, though it requires more frequent element replacement. The automatic drain clears condensate from the 108 cc bowl without an operator, which is decisive for unattended or wet lines.
