Airtac GAC F.R.L. Unit GAC500C20ALW
The AirTAC Airtac GAC F.R.L. Unit GAC500C20ALW 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 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC500C20ALW
Delivering cleaned, regulated and lubricated air for heavy pneumatic lines, this AirTAC GAC500C20ALW F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port pairs with a 2460 g mass, requiring a solid frame mount rather than tubing support. Air passes through the 5 um element first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls. A circular gauge reading MPa/psi is fitted for the default PT thread.
Equipped with a metal bowl and an automatic drain, this unit clears condensate without an operator, making it decisive for unattended or wet lines. The 108 cc drain bowl and 225 cc oil bowl dictate the service interval, and the lower-pressure type restricts the operating range to 0.15-0.4 MPa (20-58 psi). If the machine may ever need more pressure, this L type is the wrong part, as the standard type tops out at 0.9 MPa.

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 GAC500C20ALW Is Used
Textile Manufacturing Lines
Feeds multi-station weaving machines where a steady, low-pressure air supply and fine 5 um filtration protect delicate spinning nozzles from clogging.
Carton Erecting Machines
Provides lubricated air at 0.4 MPa for continuous motion folding arms and vacuum suction cups that demand reliable, steady cycling over long shifts.
Bottle Sorting Conveyors
Conditions air for high-speed diverter gates and pneumatic pushers, using the automatic drain to handle condensate in wash-down environments.
Is the Airtac GAC F.R.L. Unit GAC500C20ALW the Right Air-Prep Unit?
Choose this 3/4in model for larger duties, stepping up from the GAC400 which offers a plotted flow envelope of 6000 L/min at 0.7 MPa inlet versus this body's 7000 L/min curve. The 5 um element traps far finer particles than the 40 um standard, suiting precision valves or instrument air at the cost of more frequent element service. Because oil mist is added downstream, choose a filter-regulator instead if the line must stay oil-free. The three units are separately orderable as GAF500-20, GAR500-20 and GAL500-20, so a damaged bowl does not mean replacing the whole assembly. The lower-pressure ceiling of 0.4 MPa is about 44% of the standard type's 0.9 MPa maximum, quantifying what the buyer gives up when choosing this L type.
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 GAC500C20ALW FAQ
This lower-pressure type operates at 0.15-0.4 MPa (20-58 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, the filtering grade is 5 um, and the recommended lubricant is ISO VG 32. It features a 108 cc drain bowl, a 225 cc oil bowl, and weighs 2460 g.
The automatic drain clears condensate without an operator, which is decisive for unattended or wet lines. The metal bowl is chosen as a build and environment choice for the 1.0 MPa max pressure; confirm compatibility from the datasheet for aggressive surroundings, as no specific solvent or impact claims are printed.
