The AirTAC Airtac GAC F.R.L. Unit GAC400N15ASWK 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 5 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi).
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, 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 pressure range of 0.15-0.9 MPa (20-130 psi), while the 5 um element captures fine particulates for sensitive downstream valves. Air passes through the filter first, then the regulator, with oil mist added last so the internal regulator seat never fouls.
The nylon bowl equips this unit for environments where chemical compatibility or specific impact resistance is preferred, though buyers should confirm suitability for aggressive surroundings. An automatic drain clears condensate from the 100 cc bowl without an operator, and a circular gauge reading MPa/psi is fitted for the default PT thread. The reverse-flow (reflux) valve is attached, shown as a separate pneumatic symbol in the catalogue, and replacement parts follow the GAF400-15, GAR400-15 and GAL400-15 codes.

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 multi-axis actuators and tool changers where the 5 um element protects precision sliding parts from abrasive grit.
Supplies clean, lubricated air to high-speed diverter gates and clamping cylinders, with the auto drain handling wet plant air.
Conditions air for large loom and spinner arrays, using the 1/2in port to maintain adequate volume to multiple downstream stations.
Choose this 2390 g assembly when a mid-to-large machine requires precision filtration and steady pressure. The 5 um element traps far finer particles than the standard 40 um grade, trading off more frequent element service for better protection of instrument air or tight-clearance valves. Because the lubricator injects oil mist downstream of the regulator, select a separate filter-regulator instead if your line must remain strictly oil-free. The automatic drain suits unattended or wet lines, and the fitted reflux valve represents a specific ordering difference detailed on its own catalogue page.
Sizing against neighbouring bodies, the GAC400 flow curve is plotted to 6000 L/min at 0.7 MPa inlet, which is double the 3000 L/min envelope of the GAC300. When sizing for maximum output, remember that the 1.0 MPa maximum supply 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 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 from -5 to 70 C, weighs 2390 g, and features a 100 cc drain bowl with a 185 cc oil bowl. The recommended lubricant is ISO VG 32.
The K indicates that a reverse-flow (reflux) valve is fitted. The catalogue displays this as a distinct pneumatic symbol with full details provided on its own dedicated page.
