Airtac GAC F.R.L. Unit GAC50020SW
The AirTAC Airtac GAC F.R.L. Unit GAC50020SW 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 GAC50020SW
Delivering cleaned, pressure-set and oil-misted air for demanding pneumatics, the AirTAC GAC50020SW integrates a filter, regulator and lubricator on a single L-shape bracket. This standard type unit features a 3/4in port, a 5 um element for fine particle capture, and operates within the 0.15-0.9 MPa (20-130 psi) range. A circular gauge reading MPa/psi is fitted for the default PT thread, allowing operators to monitor the set downstream pressure directly.
Weighing 2460 g, this body size requires a solid panel or frame mount rather than tubing support. The 108 cc condensate bowl and 225 cc oil sump dictate the maintenance rhythm, while the semi-auto and manual drain pairing gives operators two ways to clear water. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of the internal pressure-control mechanism.

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 GAC50020SW Is Used
Automotive Assembly Line
Feeds a multi-station manufacturing cell where the 5 um element protects precision pneumatic grippers from fine machining debris.
High-Speed Cartoner
Supplies regulated, lubricated air to continuous motion packaging equipment, ensuring consistent actuator speed across long shifts.
CNC Tooling Header
Conditions the main 3/4in air supply drop for a machining center, providing stable 0.15-0.9 MPa pressure for tool changers and clamps.
Is the Airtac GAC F.R.L. Unit GAC50020SW the Right Air-Prep Unit?
Choose this 3/4in model when a machine header requires fine 5 um filtration alongside standard pressure regulation; stepping down to the GAC400 reduces the plotted flow envelope to 6000 L/min at 0.7 MPa inlet, while stepping up to the GAC600 increases it to 12000 L/min. The PC bowl is rated for the same 1.0 MPa maximum and -5 to 70 C temperature limits as metal or nylon alternatives, so confirm material compatibility if the environment involves aggressive solvents. If the downstream line must remain oil-free, omit the lubricator and select a filter-regulator instead. For maintenance, the assembly accepts GAF500-20, GAR500-20 and GAL500-20 replacement units. Stepping from the GAC400 to this GAC500 increases the condensate sump from 100 cc to 108 cc, an 1.08x capacity gain that extends the interval between drain interventions.
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 GAC50020SW FAQ
This standard type unit regulates from 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C, features a 5 um element, and uses ISO VG 32 lubricant. The drain bowl holds 108 cc, the oil bowl holds 225 cc, and the assembly weighs 2460 g.
The W code specifies a 5 um element instead of the standard 40 um, trapping far finer particles to protect precision valves and instrument air systems. This finer filtration causes the element to load with debris faster, requiring more frequent element service compared to the standard grade.
