The AirTAC Airtac GAC F.R.L. Unit GAC400N15ASNK 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 pneumatics, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port pairs with a standard 0.15-0.9 MPa (20-130 psi) operating range 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 pressure-control internals.
This specific configuration uses a nylon bowl and an automatic drain to clear condensate without an operator, making it well-suited for unattended machinery. No pressure gauge is supplied, but the body features a 1/4in gauge connection for adding one if visual monitoring is required later. A reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol with details on its own page.

Specifications follow the official AirTAC GAC catalogue (pages 216-217). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAC400 is 1/4" if you add one.

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 wrenches and actuators on a vehicle production line, relying on the 1/2in port to supply adequate volume for concurrent tool operation.
Conditions air for high-speed carton forming equipment where the automatic drain handles condensate continuously during three-shift operations without manual intervention.
Prepares air for heavy-load lifting cylinders on end-of-line palletizers, with the 40 um element protecting large-bore actuator seals from particulate ingress.
Choose this 2390 g GAC400 unit when a 1/2in port matches your flow requirements, stepping up from the GAC300 which offers a 3000 L/min plotted flow envelope at 0.7 MPa inlet to this body's 6000 L/min curve. The nylon bowl keeps the mass low while sharing the same 1.0 MPa maximum pressure as metal or PC variants. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. The three constituent parts are separately orderable as GAF400-15, GAR400-15 and GAL400-15. Stepping up from the GAC300 to this GAC400 roughly doubles the plotted flow envelope, providing a 2x capacity increase for larger duties.
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 standard type unit regulates from 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 operates between -5 to 70 C, uses a 40 um element, and weighs 2390 g. The drain bowl holds 100 cc and the oil bowl holds 185 cc, requiring ISO VG 32 or equivalent lubricant.
No, the N in the ordering code means no gauge is supplied. To read the outlet pressure, you must add a circular gauge to the 1/4in gauge connection on the body, matching the MPa/psi scale of the default PT thread.
