Airtac GAC F.R.L. Unit GAC600C20ASNK
The AirTAC Airtac GAC F.R.L. Unit GAC600C20ASNK 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 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC600C20ASNK
Delivering cleaned, regulated and lubricated air for heavy-duty pneumatics, this AirTAC GAC600C20ASNK F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port pairs with a 4600 g mass, placing it in the largest size class where rigid frame mounting is required rather than tubing support. Air passes through the 40 um filter first, then the regulator sets a 0.15-0.9 MPa (20-130 psi) working pressure, and the lubricator introduces oil mist downstream so the regulator seat stays clean.
Because the code carries an A, this unit uses an automatic drain to clear condensate from the 205 cc metal bowl without an operator. No gauge is supplied, but a 1/4in connection is provided if you need to add instrumentation later. The assembly includes a reverse-flow (reflux) valve, which the catalogue shows as a separate pneumatic symbol with details on its own page. Spares follow the body-port suffix: GAF600-20, GAR600-20 and GAL600-20.

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 GAC600C20ASNK Is Used
Automotive Assembly Line
Feeds a multi-station manufacturing cell where the 3/4in port and large flow envelope sustain high air demand for parallel pneumatic presses.
CNC Machining Center
Conditions air for tool changers and heavy-duty clamps, using the automatic drain to handle condensate during continuous unattended cycles.
Plastic Injection Molding
Supplies regulated and lubricated air to large mold ejection systems, relying on the 4600 g frame-mounted assembly for stable pressure.
Is the Airtac GAC F.R.L. Unit GAC600C20ASNK the Right Air-Prep Unit?
Choose this 3/4in metal-bowl unit for high-demand machine headers, stepping up from the GAC500 which plots a 7000 L/min flow envelope at 0.7 MPa inlet. The GAC600 extends that plotted curve to 12000 L/min at the same inlet, handling larger flow requirements. The automatic drain suits unattended wet lines, while the missing gauge means set pressure cannot be read without adding one to the 1/4in port. Remember that oil mist is added downstream, so choose a filter-regulator if the line must stay oil-free. The 205 cc drain bowl holds about 8x the condensate of the GAC200's 25 cc, meaning far fewer interventions.
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 GAC600C20ASNK FAQ
This standard type operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C. It features a 205 cc drain bowl, a 410 cc oil bowl, weighs 4600 g, and uses ISO VG 32 lubricant.
The N after the port means no gauge is supplied, though a 1/4in connection exists if you wish to fit one. The K indicates a reverse-flow (reflux) valve is attached, which the catalogue draws as a distinct pneumatic symbol.
