The AirTAC Airtac GAC F.R.L. Unit GAC400N15ASNW 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 mid-size pneumatics, this GAC400 unit combines a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port serves machines demanding a 0.15-0.9 MPa (20-130 psi) operating range, while the 5 um element captures fine particulates before they reach sensitive valves. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of internal components.
Built with a nylon bowl, the assembly sheds condensate via an automatic drain without operator input. The 100 cc drain capacity and 185 cc oil reservoir dictate the maintenance rhythm, stretching service intervals compared to smaller frames. No pressure gauge is supplied, but the body features a 1/4in gauge connection for adding one if visual monitoring is required later.

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 clean, lubricated air at a stable pressure to pneumatic tool change systems on machining centers.
Conditions air for high-speed packaging actuators where the 5 um element protects delicate flow controls.
Supplies mid-volume air to pneumatic clutches and brakes, relying on the 100 cc auto drain for wet environments.
Choose this configuration when a 1/2in port aligns with your flow requirements and the catalogue flow curve is plotted to 6000 L/min at 0.7 MPa inlet for sizing. The 5 um element suits instrument air or precision valves, trading off a higher resistance and more frequent service for finer filtration than the standard 40 um option. The automatic drain is decisive for unattended or wet lines, emptying the 100 cc bowl independently. If the downstream line must stay oil-free, omit the lubricator and choose a filter-regulator instead. For maintenance, the assembly breaks down into GAF400-15, GAR400-15 and GAL400-15 spares. Stepping up from the GAC300 gives exactly 2x the plotted flow envelope, as the smaller body maxes out at 3000 L/min at 0.7 MPa inlet.
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). It has a 1/2in port, a 5 um element, and an automatic drain. The drain bowl holds 100 cc and the oil bowl holds 185 cc. The unit weighs 2390 g, runs on ISO VG 32 lubricant, and functions between -5 to 70 C.
The N in the ordering code indicates no gauge is supplied from the factory. The body features a 1/4in gauge connection, allowing you to install a compatible pressure gauge separately if your setup requires direct visual verification of the regulated outlet pressure.
