The AirTAC Airtac GAC F.R.L. Unit GAC400N15ASK 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).
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this GAC400N15ASK assembly integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port pairs with a standard pressure range of 0.15-0.9 MPa (20-130 psi) and a 40 um element. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of the internal pressure-control mechanisms.
Weighing 2390 g, this body class requires a firm panel or frame mount rather than relying on the connected tubing for physical support. The unit features a nylon bowl and an automatic drain that empties the 100 cc condensate sump without operator intervention. A circular gauge is fitted, reading MPa/psi for the default PT thread, while the reverse-flow (reflux) valve is included as a distinct ordering option shown as a separate pneumatic symbol in the catalogue.

Constituent units, orderable separately as spares: GAF400-15 filter, GAR400-15 regulator, GAL400-15 lubricator — all three share this body and port.
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.

Feeds multiple pneumatic torque wrenches and actuators on a vehicle production conveyor, relying on the automatic drain to handle condensate during continuous two-shift operation.
Supplies steady 0.6 MPa air to the folding cylinders and vacuum generators in a high-speed packaging cell, with the 40 um element protecting sensitive venturi nozzles from particulate fouling.
Conditions air for pneumatic valves controlling chemical metering pumps, where the nylon bowl offers a lightweight reservoir solution compatible with the ambient factory environment.
Choose this 1/2in port configuration for medium-capacity air preparation, keeping in mind the catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet. If a smaller footprint is needed, the GAC300 offers a 60 cc drain bowl, whereas stepping up to the GAC500 provides a 108 cc sump. This specific model uses a nylon bowl, an automatic drain for unattended lines, and a standard 40 um element. The fitted gauge reads MPa/psi, and the assembly includes the reverse-flow (reflux) valve. If the downstream line must remain completely oil-free, omit the lubricator and choose a filter-regulator instead. For maintenance, the individual elements are available as GAF400-15, GAR400-15 and GAL400-15. Since 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.
Quick checklist
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.
This model operates at a standard pressure range of 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 in temperatures from -5 to 70 C, uses a 40 um element, and weighs 2390 g. The condensate drain bowl holds 100 cc, the oil bowl holds 185 cc, and the recommended lubricant is ISO VG 32.
The K signifies that a reverse-flow (reflux) valve is attached to this unit. The catalogue depicts this as a separate pneumatic symbol with details on its own page, and it is included as an ordering difference on this specific F.R.L. combination.
