Airtac GAC F.R.L. Unit GAC50020ASN
The AirTAC Airtac GAC F.R.L. Unit GAC50020ASN 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 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC50020ASN
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC GAC50020ASN combines a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port serves heavy-duty circuits, while the standard pressure range operates between 0.15-0.9 MPa (20-130 psi). A 40 um element captures solid particles, and the automatic drain clears condensate without an operator. Because the lubricator sits last in the sequence, oil mist is added downstream of the regulator seat, preventing fouling.
Weighing 2460 g, this body requires a solid panel or frame mount rather than tubing support. The unit ships without a gauge, but features a 1/4in gauge connection for adding one later. The PC bowl holds 108 cc of condensate and 225 cc of oil, setting the maintenance interval. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. Spares are available as GAF500-20, GAR500-20 and GAL500-20.

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 GAC50020ASN Is Used
Automotive Assembly Lines
Feeds large parallel grippers and heavy-duty presses on a machine header, relying on the 3/4in port to sustain volume for multi-station tools.
Palletizing Robots
Supplies oil-misted air to heavy pneumatic end-effectors that lift full pallets, with the automatic drain handling condensate during continuous shifts.
Metal Stamping Presses
Conditions air for large-capacity air-piloted valves on stamping equipment, where the 40 um element protects against scale and the 108 cc bowl catches heavy moisture.
Is the Airtac GAC F.R.L. Unit GAC50020ASN the Right Air-Prep Unit?
Select this 3/4in PC bowl model for large actuators where unattended wet lines make the automatic drain essential. The standard 0.15-0.9 MPa (20-130 psi) range covers general plant air, and the default PT thread pairs with a MPa/psi gauge scale if you add one to the 1/4in connection. For finer protection, the 5 um W element suits precision valves but needs more frequent service. Stepping down to the GAC400 drops the plotted flow envelope to 6000 L/min at 0.7 MPa inlet compared to this body's 7000 L/min, whereas stepping up to the GAC600 reaches 12000 L/min. The 1.5x proof margin of 1.5 MPa (215 psi) against the 1.0 MPa (145 psi) maximum is a burst-test boundary, not permission to run above 1.0 MPa.
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 GAC50020ASN FAQ
This model operates at 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). It functions from -5 to 70 C, uses a 40 um element, and weighs 2460 g. The drain bowl holds 108 cc and the oil bowl holds 225 cc, requiring ISO VG 32 or equivalent lubricant.
No, the N in the code means no gauge is supplied. You can install your own circular gauge using the 1/4in connection on the body, which for the default PT thread corresponds to a MPa/psi scale.
