About the Airtac GAC F.R.L. Unit GAC500N20ALNK
Delivering cleaned, regulated and lubricated air for demanding pneumatics, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. The 3/4in port serves the GAC500 body class, which carries a 108 cc condensate bowl and a 225 cc oil reservoir. Because the lubricator sits last in the sequence, oil mist enters the airstream downstream of the regulator seat, preventing fouling.
Configured for low-pressure duties, the unit regulates between 0.15-0.4 MPa (20-58 psi) and uses a 40 um element. The nylon bowl equips this assembly for environments where material compatibility dictates a non-metallic housing, and the automatic drain empties condensate without an operator. A reverse-flow (reflux) valve is fitted, which the catalogue depicts as a separate pneumatic symbol on its own page. No gauge is supplied, but the body features a 1/4in connection for adding one.

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 GAC500N20ALNK Is Used
Textile Machinery
Feeds low-pressure air to looms and spinning frames where delicate tensioning cylinders operate safely within the 0.15-0.4 MPa range.
Carton Erectors
Conditions air for folding and sealing actuators that require steady low pressure, preventing damage to lightweight cardboard materials.
Pneumatic Sorting Lines
Supplies oil-misted air to diverter gates and pushers on high-speed parcel conveyors, ensuring continuous moving-part lubrication.
Is the Airtac GAC F.R.L. Unit GAC500N20ALNK the Right Air-Prep Unit?
Choose this 2460 g assembly for 3/4in lines requiring low-pressure control up to 0.4 MPa. If a machine ever demands higher pressure, the L type is the wrong part since it tops out at roughly 44% of the standard 0.9 MPa ceiling. The automatic drain suits unattended stations, while the 40 um element balances protection and service frequency. Because oil mist is added downstream, select a separate filter-regulator if the line must remain oil-free. Spares follow the body-port suffix exactly: GAF500-20, GAR500-20 and GAL500-20. Stepping down, the flow envelope here is plotted to 7000 L/min at 0.7 MPa inlet, matching the GAC500, whereas the GAC400 curve extends only to 6000 L/min. The 1.5 MPa proof pressure provides a 1.5x burst-test margin over the 1.0 MPa maximum, though it is never permission to run above 1.0 MPa.
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 GAC500N20ALNK FAQ
This lower-pressure type operates at 0.15-0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It has a 3/4in port, a 40 um element, and a temperature range of -5 to 70 C. The drain bowl holds 108 cc and the oil bowl holds 225 cc. The unit weighs 2460 g and uses ISO VG 32 lubricant.
The N in the model code indicates no gauge is supplied. The body features a 1/4in gauge connection, allowing you to install a compatible gauge if you need to visually monitor the 0.15-0.4 MPa outlet pressure.
