Airtac GAC F.R.L. Unit GAC600C20SWK
The AirTAC Airtac GAC F.R.L. Unit GAC600C20SWK 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 GAC600C20SWK
Delivering cleaned, regulated and lubricated air for heavy-duty pneumatic headers, the AirTAC GAC600C20SWK is a complete three-unit F.R.L. combination. Pre-plumbed on a single L-shape bracket, the filter, regulator and lubricator sequence ensures oil mist is introduced downstream of the regulator seat. This 4600 g assembly features a 3/4in port and a 5 um element, trapping far finer particulate than the 40 um standard to protect precision valves.
The metal bowl equips this 600-series body for demanding industrial environments, while the fitted circular gauge reads in MPa/psi for the default PT thread. A reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue. Condensate management relies on a 205 cc drain bowl paired with a 410 cc oil reservoir, minimizing required interventions on high-flow lines.

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 GAC600C20SWK Is Used
Automotive Assembly Lines
Feeds large multi-station machine headers where a 3/4in port and 12000 L/min flow envelope sustain high actuator demand.
CNC Machining Centers
The 5 um element protects sensitive precision valves from fine particulate ingress on heavy manufacturing equipment.
Heavy Stamping Presses
A 4600 g mass and 410 cc oil reservoir provide the sustained lubrication and structural stability required by large presses.
Is the Airtac GAC F.R.L. Unit GAC600C20SWK the Right Air-Prep Unit?
Stepping up to this 600-series body provides a massive 205 cc condensate sump, roughly 2x the 108 cc capacity of the GAC500, meaning fewer manual drain cycles for unattended stations. The semi-auto and manual drain pair is fitted, dumping condensate on pressure drop or on demand. If your downstream line must remain completely oil-free, omit the lubricator and choose a dedicated filter-regulator instead. Replacement spares follow the 600-20 suffix exactly: order GAF600-20, GAR600-20 and GAL600-20 to service individual units.
The catalogue flow curve for this body is plotted to 12000 L/min at 0.7 MPa inlet, exactly double the 6000 L/min envelope of the GAC400. The standard type regulates up to 0.9 MPa, but with a 1.0 MPa maximum supply, there is only about 0.1 MPa of regulation headroom above the top setting.
Quick checklist
- ✓ Body size for your peak flow (3/4" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: Metal (C) only
- ✓ 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 205 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 4600 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 GAC600C20SWK FAQ
This standard type unit regulates 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. It operates from -5 to 70 C, weighs 4600 g, holds 205 cc in the drain bowl and 410 cc in the oil bowl, and uses ISO VG 32 lubricant.
It includes a 5 um filter element for fine filtration, a metal bowl for the 600-series body, and a fitted circular gauge reading MPa/psi. The semi-auto and manual drain pair is fitted, and a reverse-flow (reflux) valve is attached as a separate pneumatic symbol.
