The AirTAC Airtac GAC F.R.L. Unit GAC400N10SK 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 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).
Delivering cleaned, regulated and lubricated air for mid-sized pneumatics, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. The 3/8in ported body operates at 0.15-0.9 MPa (20-130 psi) and uses a 40 um element. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling during pressure modulation.
The assembly features a nylon bowl and includes a reverse-flow (reflux) valve, which the catalogue illustrates as a separate pneumatic symbol. A circular gauge is fitted, reading MPa/psi for the default PT thread. Weighing 2390 g, the unit needs a solid panel or frame mount rather than tubing support, and its 100 cc condensate bowl paired with a 185 cc oil reservoir sets the maintenance interval.

Constituent units, orderable separately as spares: GAF400-10 filter, GAR400-10 regulator, GAL400-10 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 main air headers for multi-station assembly machinery where a 3/8in port provides adequate flow to several actuators.
Conditions air for continuous motion packaging conveyors, ensuring pneumatic folding arms receive steady pressure and oil mist.
Supplies regulated air to pneumatic clamps and ejection cylinders on small to mid-sized forming presses.
Choose this GAC400 configuration for duties requiring a standard pressure range and a manual condensate routine, as it ships with both semi-auto and manual drains fitted. The 40 um element suits general plant air, while the nylon bowl offers a non-metallic housing option within the shared -5 to 70 C temperature limit. If your downstream line must remain completely oil-free, omit the lubricator and select a dedicated filter-regulator instead. For maintenance, the individual elements are separately orderable as GAF400-10, GAR400-10 and GAL400-10.
Stepping down, the GAC300 flow curve is plotted to 3000 L/min at 0.7 MPa inlet, whereas this GAC400 body is plotted to 6000 L/min, effectively doubling the available sizing envelope. When sizing the supply, remember the 1.0 MPa maximum inlet leaves only about 0.1 MPa of headroom above the 0.9 MPa standard 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 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). The temperature range is -5 to 70 C. It features a 100 cc drain bowl, a 185 cc oil bowl, and weighs 2390 g. The recommended lubricant is ISO VG 32.
The K indicates that a reverse-flow (reflux) valve is attached to the unit. The catalogue shows this component as a distinct pneumatic symbol, and specific operational details for the valve should be confirmed from its dedicated datasheet page.
