Airtac GAC F.R.L. Unit GAC500C20SNWK
The AirTAC Airtac GAC F.R.L. Unit GAC500C20SNWK 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 GAC500C20SNWK
Delivering cleaned, regulated and lubricated air for heavy pneumatic lines, the AirTAC GAC500C20SNWK is a complete F.R.L. combination pairing a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port pairs with a 2460 g mass, placing this unit in a size class that demands a solid panel or frame mount rather than tubing support. This specific code uses a 5 um element to trap far finer particles than the 40 um standard, trading element service frequency for the precision required by sensitive valves or instrument air.
Air passes through the filter, regulator and lubricator in that exact sequence, so oil mist is added downstream of the regulator seat to prevent fouling. The metal bowl equips this assembly for rugged environments, and because no gauge is supplied, the set pressure cannot be read without adding one to the 1/4in gauge connection. The reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol with details on its own page. If the downstream line must stay oil-free, omit the lubricator and choose a filter-regulator instead.

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 GAC500C20SNWK Is Used
Automotive Assembly Lines
Feeds large multi-station headers on manufacturing floors where a 3/4in port handles high air volume for sequential power tools.
Palletizing Robots
Conditions air for heavy-duty end effectors and grippers that require fine 5 um filtration to protect precision guided valves.
Woodworking Machinery
Supplies regulated, lubricated air to large pneumatic presses and clamps in dusty environments where a metal bowl adds durability.
Is the Airtac GAC F.R.L. Unit GAC500C20SNWK the Right Air-Prep Unit?
Stepping up from the GAC400 roughly increases the plotted flow envelope from 6000 to 7000 L/min at 0.7 MPa inlet, making this 3/4in body better suited for multi-station machine headers. The semi-auto and manual drain pair fitted here dumps condensate on each pressure drop or on demand, while the 108 cc drain bowl and 225 cc oil bowl dictate the maintenance interval. Operators can add a gauge reading MPa/psi for the default PT thread to the 1/4in connection. The three units are separately orderable as GAF500-20, GAR500-20 and GAL500-20, meaning a clogged element does not require replacing the whole assembly. Because the 1.5 MPa proof pressure is 1.5x the 1.0 MPa maximum, it serves strictly as a burst-test margin 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 GAC500C20SNWK FAQ
This model operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a 1.5 MPa (215 psi) proof pressure. 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 code means no gauge is supplied from the factory. You can install your own circular gauge into the 1/4in gauge connection on the regulator body to monitor the 0.15-0.9 MPa set pressure.
