Airtac GAC F.R.L. Unit GAC600C25ASNWK
The AirTAC Airtac GAC F.R.L. Unit GAC600C25ASNWK 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 GAC600C25ASNWK
Delivering cleaned, pressure-set and oil-misted air for heavy-duty pneumatics, this GAC600C25ASNWK assembly integrates a filter, regulator and lubricator on a single L-shape bracket. The 1in port pairs with a 4600 g mass, dictating a firm panel or frame mount rather than tubing support. 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. A 5 um element captures fine particulates for precision circuits, while the metal bowl suits demanding plant environments.
Because the code carries an N after the port, no circular gauge is supplied; operators must add one to the 1/4in gauge connection to read the set pressure. The automatic drain clears condensate from the 205 cc bowl without an operator, which is decisive for unattended or wet lines. This model also includes a reverse-flow (reflux) valve, which the catalogue shows as a separate pneumatic symbol with details on its own page. The three constituent units are separately orderable as GAF600-25, GAR600-25 and GAL600-25.

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 GAC600C25ASNWK Is Used
Automotive Assembly Plant Headers
Feeds a main 1in distribution header supplying multiple pneumatic stamping and robotic lines, relying on the 5 um element to protect sensitive directional valves.
High-Speed Bottling Lines
Conditions air for a large multi-station bottling machine where the automatic drain handles condensate continuously without halting production.
CNC Machining Centers
Prepares air for heavy multi-axis CNC actuators, using the metal bowl and reverse-flow valve to manage high-volume, demanding factory environments.
Is the Airtac GAC F.R.L. Unit GAC600C25ASNWK the Right Air-Prep Unit?
Choose this 1in port body for large-scale air preparation, stepping up from the GAC500 which offers a 7000 L/min plotted flow envelope at 0.7 MPa inlet. The GAC600 extends that sizing curve to 12000 L/min, accommodating substantially higher flow demands. The 5 um element (W) traps far finer particles than the standard 40 um grade, making it ideal for precision valves or instrument air, at the cost of more frequent element service. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. Remember that the PT thread sets a MPa/psi scale for any added gauge.
For sizing, the 205 cc condensate bowl holds about 8x the capacity of the GAC200's 25 cc drain bowl, drastically reducing intervention frequency on high-flow lines.
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 GAC600C25ASNWK FAQ
This standard type unit regulates pressure from 0.15-0.9 MPa (20-130 psi) and carries a maximum pressure of 1.0 MPa (145 psi) with a 1.5 MPa (215 psi) proof rating. Operating temperature spans -5 to 70 C. The metal bowl drain capacity is 205 cc and the oil bowl holds 410 cc, with a total weight of 4600 g. The recommended lubricant is ISO VG 32.
The N in the model code indicates no gauge is supplied; you must fit a circular gauge to the 1/4in connection to read the downstream pressure. The K code means a reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue. The 5 um element provides finer filtration than the 40 um standard for sensitive pneumatic circuits.
