AirTAC GAC400 · F.R.L. Combination (Filter + Regulator + Lubricator)

Airtac GAC F.R.L. Unit GAC400N15SNW

The AirTAC Airtac GAC F.R.L. Unit GAC400N15SNW 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).

About the Airtac GAC F.R.L. Unit GAC400N15SNW

Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC GAC400N15SNW F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. It features a 1/2in port, a standard pressure range of 0.15-0.9 MPa (20-130 psi) and a 5 um element that captures fine particles for sensitive valves. The 2390 g mass requires a firm panel or frame mount rather than tubing support.

The nylon bowl equips this unit with a 100 cc condensate capacity and a 185 cc oil reservoir, reducing maintenance frequency compared to smaller bodies. Because no gauge is supplied, the set pressure cannot be read without adding one to the 1/4in gauge connection. Air flows through the filter first, then the regulator, with oil mist injected last downstream of the regulator seat to prevent fouling.

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.

Where the Airtac GAC F.R.L. Unit GAC400N15SNW Is Used

factory

Automotive Assembly Lines

Feeds main air headers for robotic welding cells where a 1/2in port and 5 um filtration protect precision grippers from particulate ingress.

packaging

Carton Sealing Machinery

Conditions air for high-speed pneumatic fold arms and glue guns, relying on the 100 cc drain bowl to handle moisture from continuous duty cycles.

precision_manufacturing

CNC Tool Changers

Supplies stable 0.15-0.9 MPa pressure to automatic tool changers, ensuring consistent actuator force while the lubricator oils internal moving seals.

Is the Airtac GAC F.R.L. Unit GAC400N15SNW the Right Air-Prep Unit?

Choose this GAC400 body for mid-to-high flow duties, noting the catalogue flow curve is plotted to 6000 L/min at 0.7 MPa inlet, which is double the GAC300 envelope of 3000 L/min. The 5 um W element traps far finer particulate than the standard 40 um grade, trading element service frequency for cleaner downstream air. A semi-auto and manual drain pair is fitted, while the N code means no gauge is included. If your line must stay oil-free, select a filter-regulator instead because this lubricator adds oil mist downstream. Replacement spares are GAF400-15, GAR400-15 and GAL400-15. Stepping up from the GAC300 gives you a 1.7x larger drain bowl capacity, dropping your condensate interventions significantly.

Installation & Maintenance Notes

  • check Install with the airflow arrow: filter first, lubricator last.
  • check Keep inlet pressure at or below 1.0 MPa (145 psi).
  • check Fill the oil bowl with ISO VG 32 or equivalent only.
  • check Drain condensate before the 100 cc bowl fills.
  • check Keep the unit above freezing (-5 to +70 °C, unfreeze).
  • check Support the 2390 g unit on its bracket, not on the tubing.

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.

Airtac GAC F.R.L. Unit GAC400N15SNW FAQ

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, a 5 um element and weighs 2390 g. The recommended lubricant is ISO VG 32 or equivalent.

The N in the ordering code indicates no gauge is supplied. The body has a 1/4in gauge connection, so you must install a separate PT-threaded gauge reading in MPa/psi to verify the 0.15-0.9 MPa setpoint.
