Airtac GAC F.R.L. Unit GAC50020SNW
The AirTAC Airtac GAC F.R.L. Unit GAC50020SNW 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 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC50020SNW
Delivering cleaned, regulated and lubricated air for heavy pneumatic demands, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port serves as the inlet for the 5 um element, which captures fine particles before the standard regulator sets the downstream pressure between 0.15-0.9 MPa (20-130 psi). Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling.
Weighing 2460 g, the assembly requires a solid frame mount rather than tubing support, and its 225 cc oil bowl reduces the frequency of refills on continuous lines. This specific code ships without a pressure gauge, leaving the 1/4in gauge connection open for operators to add a preferred instrument. Condensate is managed by a semi-auto drain that dumps on pressure drops alongside a manual override.

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 GAC50020SNW Is Used
Automotive Assembly Lines
Feeds large robotic welding arms and body panel handling actuators that rely on a steady supply of finely filtered, lubricated air.
Palletizing Stations
Conditions air for heavy-duty pneumatic grippers and stretch wrap machinery where high flow and consistent pressure are critical.
CNC Machining Centers
Protects sensitive tool changers and air-blast clearing systems by trapping fine particulates down to 5 um before they reach the spindle.
Is the Airtac GAC F.R.L. Unit GAC50020SNW the Right Air-Prep Unit?
Choose this 3/4in body when a machine demands high flow capacity, as the catalogue flow curve for the GAC500 is plotted to 7000 L/min at 0.7 MPa inlet, compared to the GAC600 which extends to 12000 L/min. The 5 um element provides finer protection for precision valves than the standard 40 um grade, though it will require more frequent replacement. If the downstream line must remain oil-free, omit the lubricator and select a filter-regulator instead. For maintenance, the individual components are separately orderable as GAF500-20, GAR500-20 and GAL500-20. Stepping up from the GAC400 to this body increases the oil capacity from 185 cc to 225 cc, yielding a 1.2x service interval extension.
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 GAC50020SNW FAQ
This standard type unit operates within a pressure range of 0.15-0.9 MPa (20-130 psi) and handles a maximum pressure of 1.0 MPa (145 psi) with a 1.5 MPa (215 psi) proof pressure. The operating temperature spans -5 to 70 C. It features a 108 cc drain bowl and a 225 cc oil bowl, weighs 2460 g, and requires ISO VG 32 or equivalent lubricant.
The N in the product code indicates that no circular gauge is supplied from the factory. The unit features a 1/4in gauge connection, allowing operators to install a specific PT-thread gauge reading in MPa/psi that suits their monitoring preferences.
