Airtac GAC F.R.L. Unit GAC600C25SWK
The AirTAC Airtac GAC F.R.L. Unit GAC600C25SWK 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 1" ports, a 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC600C25SWK
Delivering cleaned, regulated and lubricated air for large-scale pneumatic systems, this GAC600C25SWK is a complete three-unit F.R.L. combination built on a single L-shape bracket. Air passes through the filter, regulator and lubricator in that exact sequence, meaning the oil mist is introduced downstream of the regulator seat to prevent fouling. The 1in port and 4600 g mass place this unit in the largest size class, requiring a solid frame or panel mount rather than tubing support.
This specific configuration uses a metal bowl paired with a 5 um element for trapping fine particles in precision valve or instrument air lines. It operates at 0.15-0.9 MPa (20-130 psi) and includes a circular gauge reading MPa/psi for the default PT thread. A reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol with details on its own page.

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 GAC600C25SWK Is Used
Automotive Assembly Lines
Feeds main air headers distributing cleaned and lubricated air to multiple robotic welding and handling stations across a plant.
High-Speed Bottling Plants
Supplies stable pressure and fine 5 um filtration to large pneumatic actuators driving high-throughput filling capping machinery.
CNC Machine Tool Shops
Prepares instrument-quality air for heavy-duty CNC tool changers and clamping systems requiring consistent lubrication.
Is the Airtac GAC F.R.L. Unit GAC600C25SWK the Right Air-Prep Unit?
Choose this 1in port model for high-demand machine headers or multi-station lines, stepping up from the GAC500 which offers a 7000 L/min plotted flow envelope at 0.7 MPa inlet. The 5 um element here provides finer filtration than the standard 40 um grade, though it requires more frequent element service. The unit ships with both a semi-auto and manual drain fitted, and the metal bowl suits rugged environments where PC or nylon might be unsuitable. If the downstream line must stay oil-free, omit the lubricator and choose a filter-regulator instead. Spares are ordered individually as GAF600-25, GAR600-25 and GAL600-25. The 205 cc condensate bowl holds about 8x the capacity of the GAC200's 25 cc bowl, drastically reducing intervention frequency.
Quick checklist
- ✓ Body size for your peak flow (1" 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 GAC600C25SWK FAQ
This standard type unit regulates between 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, weighs 4600 g, has a 205 cc drain bowl and a 410 cc oil bowl, and uses ISO VG 32 or equivalent lubricant.
The W indicates a 5 um element for finer filtration than the default 40 um, ideal for protecting sensitive valves. The K means a reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue, though its operational function should be confirmed from datasheet page 235.
