Airtac GAC F.R.L. Unit GAC400C15S
The AirTAC Airtac GAC F.R.L. Unit GAC400C15S 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 1/2" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC400C15S
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this GAC400C15S F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port pairs with a 2390 g body mass, placing it firmly in a mid-to-high size class that requires a solid panel or frame mount rather than tubing support. The metal bowl equips this unit for rugged industrial environments, while the standard 40 um element captures solid particulates before they reach downstream valves.
Air passes through the filter, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls. The standard type provides a 0.15-0.9 MPa (20-130 psi) operating range, and a circular gauge is fitted to read the set pressure in MPa/psi for the default PT thread. The 100 cc condensate bowl and 185 cc oil reservoir dictate the maintenance rhythm, offering a larger fluid capacity than smaller bodies to extend service intervals.

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 GAC400C15S Is Used
Automotive Assembly Lines
Feeds main air headers for multi-station welding cells where a 1/2in port and 6000 L/min flow envelope sustain high actuator demand.
Palletizing Robots
Conditions air for heavy-duty end effectors, relying on the 185 cc oil bowl to maintain consistent lubrication over long automated cycles.
CNC Machine Tooling
Protects precision valves and spindles from particulate ingress using the 40 um element within a rugged metal bowl assembly.
Is the Airtac GAC F.R.L. Unit GAC400C15S the Right Air-Prep Unit?
Choose this mid-size assembly when a machine demands substantial flow capacity, noting the catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, which is double the GAC300's 3000 L/min envelope. The metal bowl offers durability for harsh surroundings, though buyers should confirm chemical compatibility for aggressive solvents. It carries a semi-auto and manual drain pair, where the semi-auto dumps condensate on each pressure drop and the manual operates on demand. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. Spares follow the body-port suffix exactly: GAF400-15, GAR400-15 and GAL400-15. Because the maximum supply is 1.0 MPa and the standard type regulates to 0.9 MPa, there is only about 0.1 MPa of headroom above the top setting, so plan a supply near 1.0 MPa if you truly need 0.9 MPa out.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 2390 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 GAC400C15S FAQ
This unit 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 features a 1/2in port, a 100 cc drain bowl, a 185 cc oil bowl, a 40 um element, and weighs 2390 g. The operating temperature is -5 to 70 C, and the recommended lubricant is ISO VG 32.
It ships with both a semi-auto drain, which expels condensate automatically when pressure drops, and a manual drain for on-demand emptying. A circular gauge is factory-fitted, reading in MPa and psi to match the standard PT thread, allowing operators to monitor the regulated pressure directly at the unit.
