Airtac GAC F.R.L. Unit GAC500C20LWK
The AirTAC Airtac GAC F.R.L. Unit GAC500C20LWK 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 GAC500C20LWK
Delivering cleaned, regulated and lubricated air for larger pneumatic setups, this GAC500C20LWK 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 body mass, requiring a firm panel or frame mount rather than tubing support. Air passes through the 5 um element before the regulator sets a lower 0.15-0.4 MPa (20-58 psi) output, with oil mist introduced last so the regulator seat stays clean.
A metal bowl equips this unit alongside a semi-auto and manual drain pair, giving operators two ways to clear the 108 cc condensate sump. The fitted circular gauge reads MPa/psi for the default PT thread, letting technicians verify the set pressure directly. This variant also includes a reverse-flow (reflux) valve, 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 GAC500C20LWK Is Used
Textile Machinery Headers
Feeds low-pressure air distribution lines for weaving looms where delicate yarn handling requires a regulated 0.4 MPa ceiling and fine 5 um filtration.
Carton Folding Lines
Supplies oil-misted air to multi-station folding cylinders, relying on the 225 cc oil bowl to sustain long production runs between maintenance interventions.
Light-Item Sorting Belts
Conditions air for diverter actuators on parcel conveyors, using the semi-auto drain to expel condensate during each pressure drop cycle.
Is the Airtac GAC F.R.L. Unit GAC500C20LWK the Right Air-Prep Unit?
Choose this 3/4in body for substantial air flows, noting the catalogue flow curve for the GAC500 is plotted to 7000 L/min at 0.7 MPa inlet, compared to the 12000 L/min envelope of the larger GAC600. If the machinery requires standard pressure up to 0.9 MPa instead of the lower 0.15-0.4 MPa range, select an S type. The 5 um element traps finer particles than the 40 um standard, suiting precision valves but demanding more frequent element service. Because oil mist is added downstream, choose a filter-regulator if the line must stay oil-free. Spares follow the GAF500-20, GAR500-20 and GAL500-20 codes. Keep in mind the 0.4 MPa ceiling is 44% of the Standard type's 0.9 MPa maximum, so verify your actuators can operate within this lower band.
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.
