Airtac GAC F.R.L. Unit GAC50020ASK
The AirTAC Airtac GAC F.R.L. Unit GAC50020ASK 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 GAC50020ASK
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this GAC50020ASK assembly integrates a filter, regulator and lubricator on a single L-shape bracket. The 3/4in port pairs with a 2460 g mass, placing it in a heavy-duty size class that requires a solid frame mount rather than tubing support. Air passes through the 40 um element first, then the regulator, ensuring oil mist is added downstream so the regulator seat never fouls. A circular gauge is fitted, reading MPa/psi for the default PT thread.
This specific configuration uses an automatic drain to clear condensate without an operator, a decisive feature for unattended or wet lines, feeding into a 108 cc drain bowl and a 225 cc oil reservoir. The reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol with details on its own page. If the downstream line must stay oil-free, omit the lubricator and choose a filter-regulator instead.

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 GAC50020ASK Is Used
Automotive Assembly Line
Feeds a multi-station machine header where the 3/4in port and automatic drain sustain continuous actuator cycling without manual condensate intervention.
Palletizing Cell
Supplies oil-misted air to heavy pneumatic grippers and pushers, relying on the 225 cc oil bowl to extend service intervals between operator visits.
Woodworking Machinery
Conditions air for large bore cylinders driving presses and clamps, with the 40 um element capturing bulk moisture and sawdust before the regulator.
Is the Airtac GAC F.R.L. Unit GAC50020ASK the Right Air-Prep Unit?
Choose this 3/4in body when a machine header demands a 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 12000 L/min envelope of the larger GAC600. The PC bowl, automatic drain and standard 0.15-0.9 MPa (20-130 psi) pressure range suit general plant air, while the fitted gauge lets operators verify the set pressure directly. Should a clogged element or damaged bowl occur, the three units are separately orderable as GAF500-20, GAR500-20 and GAL500-20 spares. Stepping down to the GAC400 halves the flow envelope to 6000 L/min, whereas this 2460 g unit provides a 1.5x proof pressure margin against its 1.0 MPa maximum.
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 GAC50020ASK FAQ
This standard type operates at 0.15-0.9 MPa (20-130 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). It has a 3/4in port, a 108 cc drain bowl, a 225 cc oil bowl, weighs 2460 g, runs from -5 to 70 C, and uses ISO VG 32 lubricant.
The K indicates a reverse-flow (reflux) valve is attached. The catalogue draws this as a separate pneumatic symbol on its own page, representing an ordering difference on this specific F.R.L. combination.
