About the Airtac GAC F.R.L. Unit GAC50020SWK
Delivering cleaned, regulated and lubricated air for demanding pneumatics, the AirTAC GAC50020SWK integrates a filter, regulator and lubricator on a single L-shape bracket. This pre-plumbed assembly eliminates inter-unit tubing, reducing potential leak paths during installation. Outfitted with a 3/4in port, the unit operates within a 0.15-0.9 MPa (20-130 psi) standard pressure range and utilizes a 5 um element to capture fine particles before they reach sensitive downstream valves.
Weighing 2460 g, this body size demands a solid panel or frame mount rather than relying on connected tubing for support. The sequence of operation ensures air passes through the filter first, then the regulator, with oil mist added last so the internal regulator seat never fouls. A circular gauge is fitted to read the set pressure in MPa/psi, and the assembly carries a reverse-flow (reflux) valve, shown in the catalogue as a distinct pneumatic symbol.

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 GAC50020SWK Is Used
Automotive Assembly Lines
Feeds main air headers for multi-station robotic welding cells, ensuring consistent pressure and fine 5 um filtration for sensitive pneumatic grippers.
High-Speed Carton Sealers
Conditions air for continuous-duty folding cylinders and glue applicators, providing the exact oil mist needed to prolong actuator seal life.
Material Handling Sorters
Supplies clean, regulated air to diverter actuators on high-throughput parcel conveyors where unattended operation and reliable pressure are critical.
Is the Airtac GAC F.R.L. Unit GAC50020SWK the Right Air-Prep Unit?
Choose this configuration for mid-to-large air preparation duties where capturing very fine particulates is essential. The 5 um element provides superior protection for precision valves and instrument air compared to the standard 40 um grade, though it will require more frequent element replacement. The PC bowl is paired with a semi-auto and manual drain, giving operators the flexibility to clear the 108 cc condensate reservoir on demand or automatically on pressure drops. If your downstream process requires strictly oil-free air, you must omit the lubricator and select a dedicated filter-regulator instead, as this unit actively injects oil mist into the line. Replacement components are available separately as GAF500-20, GAR500-20 and GAL500-20, meaning a clogged filter or damaged bowl does not require replacing the entire assembly. Stepping up to the GAC600 roughly doubles the plotted flow envelope to 12000 L/min at 0.7 MPa inlet compared to this unit's 7000 L/min, but the GAC500 holds a 1.5x overpressure margin with its 1.5 MPa proof pressure against the 1.0 MPa maximum.
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 GAC50020SWK FAQ
This F.R.L. combination handles air with a 5 um filtering grade. The standard pressure range is 0.15-0.9 MPa (20-130 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 and uses ISO VG 32 lubricant. The drain bowl holds 108 cc, the oil bowl holds 225 cc, and the unit weighs 2460 g.
The K in the model code indicates a reverse-flow (reflux) valve is fitted, which the catalogue draws as a separate pneumatic symbol with details on its own page. Additionally, because there is no N after the port code, a circular gauge is supplied and fitted; the default PT thread sets the gauge scale to read in MPa/psi.
