Airtac GAC F.R.L. Unit GAC400C15LWK
The AirTAC Airtac GAC F.R.L. Unit GAC400C15LWK 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 GAC400C15LWK
Delivering cleaned, pressure-set and lubricated air for demanding pneumatics, this GAC400 unit combines 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 metal bowl. Because it is the lower-pressure L type, the regulating range spans 0.15-0.4 MPa (20-58 psi). The build sequence routes air through the filter first, then the regulator, adding oil mist last so the regulator seat never fouls.
Weighing 2390 g, this body requires a solid panel or frame mount rather than tubing support. The 100 cc condensate bowl and 185 cc oil sump dictate the maintenance rhythm, and the unit carries a reverse-flow (reflux) valve shown as a separate pneumatic symbol in the catalogue. A circular gauge is fitted, reading MPa/psi for the default PT thread, and the temperature range is -5 to 70 C without freezing.

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 GAC400C15LWK Is Used
Precision Valve Arrays
Feeds sensitive directional valves in packaging machinery using the 5 um element to prevent spool sticking.
Low-Force Assembly Presses
Regulates air to 0.4 MPa for delicate pressing tasks, ensuring consistent low-force actuation without overdriving cylinders.
Laboratory Pneumatic Tools
Conditions air for benchtop scientific instruments requiring a stable, lower-pressure supply and added lubrication for moving parts.
Is the Airtac GAC F.R.L. Unit GAC400C15LWK the Right Air-Prep Unit?
Choose this assembly for 1/2in lines needing fine 5 um filtration and low-pressure regulation. The metal bowl suits rugged environments where standard PC might not be specified. It ships with both semi-auto and manual drains, while the fitted gauge lets operators verify the 0.15-0.4 MPa (20-58 psi) setpoint directly. If the downstream line must remain oil-free, omit the lubricator and select a filter-regulator instead. Spares follow the 400-15 suffix exactly: GAF400-15, GAR400-15 and GAL400-15.
The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, whereas the GAC300 reaches 3000 L/min, giving this body double the envelope for sizing. Because the L type tops out at 0.4 MPa, it provides only 44% of the standard 0.9 MPa ceiling.
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 GAC400C15LWK FAQ
This lower-pressure type operates at 0.15-0.4 MPa (20-58 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, a metal bowl, and weighs 2390 g. The drain bowl holds 100 cc and the oil bowl holds 185 cc. The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32.
The K signifies that a reverse-flow (reflux) valve is attached. The catalogue depicts this as a distinct pneumatic symbol with details on its own page. This model also includes the semi-auto and manual drain pair, a fitted circular gauge reading MPa/psi, and a 5 um filter element.
