About the Airtac GAC F.R.L. Unit GAC50020LNWK
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port pairs with a 5 um element to capture fine particulates before they reach precision valves. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of internal components.
Configured for low-pressure duties, the unit regulates between 0.15-0.4 MPa (20-58 psi). It carries a PC bowl and relies on a semi-auto and manual drain pair. No gauge is supplied, but a 1/4in connection is ready if you need to add instrumentation. The reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue.

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 GAC50020LNWK Is Used
Textile Machinery Headers
Feeds low-pressure air looms and spinning frames where a 3/4in line distributes steady 0.4 MPa supply across multiple actuator stations.
Carton Erector Lines
Conditions air for pneumatic folding arms and sealing presses, using the 5 um element to protect closely toleranced gripper jaws from grit.
Chemical Dosing Skids
Regulates flow to metering valves on skid packages, benefiting from the reverse-flow valve to manage downstream pressure spikes safely.
Is the Airtac GAC F.R.L. Unit GAC50020LNWK the Right Air-Prep Unit?
Choose this 2460 g assembly for substantial air preparation needs, ensuring it is mounted to a frame rather than supported by tubing. The 108 cc condensate bowl and 225 cc oil sump reduce maintenance frequency compared to smaller bodies. If your application requires oil-free output downstream, omit the lubricator and select a filter-regulator instead. For replacements, order GAF500-20, GAR500-20 and GAL500-20. Stepping up to the GAC600 roughly doubles the flow envelope to 12000 L/min at 0.7 MPa inlet against this body's 7000 L/min curve, but remember that 0.4 MPa is 44% of the standard 0.9 MPa ceiling.
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 GAC50020LNWK 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). It functions from -5 to 70 C, uses a 5 um element, and weighs 2460 g. The drain bowl holds 108 cc and the oil bowl 225 cc, requiring ISO VG 32 lubricant.
The N in the ordering code means no gauge is supplied. The body features a 1/4in gauge connection, allowing you to install a PT-threaded gauge reading MPa/psi if visual pressure verification is needed for your specific setup.
