The AirTAC Airtac GAC F.R.L. Unit GAC400N15ASNWK 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 unit integrates a filter, regulator and lubricator on a single L-shape bracket. It features a 1/2in port, a 5 um element for fine particle retention, and operates within the 0.15-0.9 MPa (20-130 psi) standard pressure range. The 2390 g mass requires a firm panel or frame mount rather than tubing support.
This specific configuration uses a nylon bowl and an automatic drain to clear condensate without operator intervention. Because no gauge is supplied, the set pressure cannot be read without adding one to the 1/4in gauge connection. The reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue. Oil mist is added downstream of the regulator to prevent seat fouling.

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.

Supplies finely filtered, lubricated air at a stable pressure to pneumatic tool changers and actuated clamps on CNC machining centers.
Conditions air for continuous motion packaging equipment where the automatic drain handles condensate during unattended shift operations.
Feeds high-flow pilot and directional valves on automated stamping presses, protecting precision internal parts with 5 um filtration.
Choose this 1/2in port body for mid-to-heavy duties, stepping up from the GAC300 which offers a 3000 L/min plotted flow envelope at 0.7 MPa inlet. The 5 um W element traps far finer particles than the standard 40 um grade, suiting precision valves at the cost of more frequent element service. The automatic drain suits unattended or wet lines, while the nylon bowl offers a different build choice than the standard PC or metal options. If the downstream line must stay oil-free, omit the lubricator and choose a filter-regulator instead. Spares are ordered individually as GAF400-15, GAR400-15 and GAL400-15. The 100 cc condensate bowl holds exactly 1.67x the capacity of the GAC300's 60 cc bowl, meaning fewer maintenance interventions.
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 max 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 N in the product code indicates no gauge is supplied. To read the set pressure, an operator must add a circular gauge to the 1/4in connection port. The default PT thread sets the expected gauge scale to MPa/psi.
