Airtac GAC F.R.L. Unit GAC50020LNW
The AirTAC Airtac GAC F.R.L. Unit GAC50020LNW 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 GAC50020LNW
Delivering cleaned, regulated and lubricated air for demanding pneumatic lines, this AirTAC GAC50020LNW combines a filter, regulator and lubricator on a single L-shape bracket. It features a 3/4in port and uses a 5 um element to capture fine particles before they reach downstream valves. The lower-pressure type restricts the operating range to 0.15-0.4 MPa (20-58 psi), making it suitable for sensitive actuators rather than high-force cylinders.
The assembly includes a 108 cc condensate bowl and a 225 cc oil reservoir, reducing the frequency of maintenance visits. Because no gauge is supplied from the factory, the set pressure cannot be read directly without adding a separate instrument to the 1/4in gauge connection. Air passes through the filter first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls.

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 GAC50020LNW Is Used
Low-Force Assembly Jigs
Feeds metered, low-pressure air at 0.15-0.4 MPa to delicate pick-and-place actuators on electronics assembly lines.
Film Wrapping Machines
Protects sensitive tensioning cylinders in packaging equipment by removing 5 um particulates and adding a controlled oil mist.
Textile Plant Headers
Conditions the main 3/4in air supply for textile machinery where standard high pressures would damage fragile fiber-handling components.
Is the Airtac GAC F.R.L. Unit GAC50020LNW the Right Air-Prep Unit?
Choose this 2460 g unit when a 3/4in line requires low-pressure regulation and fine 5 um filtration. The PC bowl is standard, but buyers should confirm material compatibility for aggressive environments. It carries both a semi-auto and a manual drain, giving operators flexibility in how condensate is cleared. If the downstream process requires absolutely oil-free air, omit the lubricator and select a dedicated filter-regulator instead. For maintenance, the individual elements and bowls are orderable as GAF500-20, GAR500-20 and GAL500-20.
The catalogue flow curve for the GAC500 is plotted to 7000 L/min at 0.7 MPa inlet, which is roughly 1.17x the 6000 L/min envelope of the GAC400. Keep in mind the 0.4 MPa ceiling is 44% of the 0.9 MPa standard type limit.
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 GAC50020LNW FAQ
This lower-pressure F.R.L. combination 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). The temperature range is -5 to 70 C. It features a 108 cc drain bowl, a 225 cc oil bowl, a 5 um element, and weighs 2460 g. The recommended lubricant is ISO VG 32.
The N in the model code indicates no gauge is supplied. To read the outlet pressure, an operator must install a separate gauge into the 1/4in gauge connection on the regulator body.
