Airtac GAC F.R.L. Unit GAC500N20ASNW
The AirTAC Airtac GAC F.R.L. Unit GAC500N20ASNW 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 GAC500N20ASNW
This GAC500 unit combines a filter, regulator and lubricator into a single pre-assembled line, with the three stages mounted on one L-shape bracket using quick clamps. The 3/4in port and 2460 g mass place it in the mid-large size class, suited to feeding a machine header rather than a single actuator. Air passes through the 5 um filter element, then the regulator holding 0.15-0.9 MPa (20-130 psi), and finally the lubricator adds oil mist downstream of the regulator so the oil never reaches the regulator seat.
The nylon bowl is a build choice for environments where a transparent polycarbonate bowl is not preferred, though the common specification of 1.0 MPa (145 psi) maximum pressure and -5 to 70 C temperature range applies regardless of bowl material. With no gauge supplied, the set pressure cannot be read directly on the unit; the 1/4in gauge connection allows a gauge to be added later if needed. The automatic drain clears condensate from the 108 cc bowl without operator intervention, which suits installations where regular manual draining would be overlooked.

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 GAC500N20ASNW Is Used
Machine tool header
Feed a 3/4in header supplying multiple pneumatic actuators on a CNC machining center, where the 5 um element protects precision solenoid valves from fine wear particles.
Assembly line lubrication
Condition air for a multi-station assembly conveyor where the automatic drain prevents water carryover into downstream cylinders and the lubricator maintains a consistent oil mist for moving parts.
Packaging equipment
Supply a carton erector or case packer with cleaned, regulated and lubricated air, with the 108 cc bowl and auto drain reducing maintenance stops on a high-cycling line.
Is the Airtac GAC F.R.L. Unit GAC500N20ASNW the Right Air-Prep Unit?
Choose this GAC500N20ASNW when the line needs 3/4in ports and the 2460 g weight of the unit can be supported by a panel or frame rather than the tubing. The automatic drain is the right call for unattended operation or wet compressed air, and the 5 um element traps finer particles than the standard 40 um grade for downstream precision valves, though it will need more frequent servicing. The nylon bowl is selected here; confirm it suits the surrounding environment, as the catalogue does not publish chemical or impact data for bowl materials. The standard pressure type covers 0.15-0.9 MPa (20-130 psi), and the PT thread carries a MPa/psi gauge scale if a gauge is added. Replacement units are separately orderable as GAF500-20, GAR500-20 and GAL500-20, so a clogged element does not mean replacing the whole assembly. The 108 cc condensate bowl of this GAC500 holds about 4.3x the condensate of a GAC300's 60 cc bowl, so the larger body needs far less frequent attention.
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 GAC500N20ASNW FAQ
This F.R.L. combination operates over 0.15-0.9 MPa (20-130 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 and the recommended lubricant is ISO VG 32. The drain bowl holds 108 cc and the oil bowl holds 225 cc. The unit weighs 2460 g and has a 3/4in port.
The N after the port code means no pressure gauge is supplied with the unit. The gauge connection on the GAC500 is 1/4in, so a gauge can be added later if you need to read the set pressure directly on the regulator. The PT thread on this model would use a gauge with an MPa/psi scale.
