Airtac GAC F.R.L. Unit GAC400N15LWK
The AirTAC Airtac GAC F.R.L. Unit GAC400N15LWK 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 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC400N15LWK
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC F.R.L. combination 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 a nylon bowl. The lower-pressure type restricts the operating range to 0.15-0.4 MPa (20-58 psi), making it suitable for sensitive actuators.
Air passes through the filter, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls. The 2390 g assembly includes a semi-auto and manual drain pair, a fitted circular gauge reading MPa/psi, and a reverse-flow valve shown as a separate pneumatic symbol in the catalogue. If the downstream line must remain oil-free, select a filter-regulator instead and omit the lubricator.

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 GAC400N15LWK Is Used
Precision Valve Manifolds
Feeds instrument air to sensitive solenoid banks using the 5 um element, protecting tight tolerances in packaging machinery.
Low-Force Assembly Jigs
Supplies a stable 0.15-0.4 MPa output to delicate pneumatic grippers on an automated assembly line, preventing over-pressurization.
Material Handling Diverters
Conditions air for low-pressure actuator diverters on a conveyor, adding necessary oil mist to extend cylinder seal life.
Is the Airtac GAC F.R.L. Unit GAC400N15LWK the Right Air-Prep Unit?
This 1/2in unit sits in the GAC400 size class, offering a 100 cc condensate bowl and a 185 cc oil reservoir. The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, double the 3000 L/min envelope of the GAC300, providing a clear path to size up or down. The 5 um element traps far finer particles than the standard 40 um grade, ideal for precision valves, though it requires more frequent service. The nylon bowl matches the standard 1.0 MPa max and -5 to 70 C limits, but confirm compatibility for aggressive surroundings. Spares follow the body-port suffix: GAF400-15, GAR400-15 and GAL400-15. Choosing the lower-pressure type means the 0.4 MPa ceiling is just 44% of the 0.9 MPa standard limit, so if the machine may ever need more pressure, this is the wrong part.
Quick checklist
- ✓ Body size for your peak flow (1/2" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
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 GAC400N15LWK FAQ
The lower-pressure type operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). 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. Use ISO VG 32 or equivalent lubricant.
The K denotes that a reverse-flow (reflux) valve is fitted. The catalogue presents this as a distinct pneumatic symbol with its own dedicated page, and it is included as an ordering difference on this assembly.
