About the Airtac GAC F.R.L. Unit GAC400C15ALWK
Delivering cleaned, regulated and lubricated air for mid-size pneumatic setups, this GAC400C15ALWK combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port pairs with a 2390 g body mass, requiring a firm panel mount rather than tubing support. It features a 5 um element for capturing fine particles and operates within the 0.15-0.4 MPa (20-58 psi) lower pressure band.
Air passes through the filter, then the regulator, and finally the lubricator, ensuring oil mist is introduced downstream so the regulator seat stays clean. The metal bowl houses a 100 cc condensate capacity and a 185 cc oil reservoir, while the automatic drain clears liquid without an operator. A reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue, and a circular gauge reading MPa/psi is included for the default PT thread.

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 GAC400C15ALWK Is Used
Precision Valve Manifolds
Feeds sensitive directional control valves requiring low 0.4 MPa operating pressure and 5 um filtered, lubricated air to prevent sticking.
Packaging Line Conveyors
Conditions air for pneumatic grippers and diverters on mid-size packaging equipment where the 1/2in port and 6000 L/min envelope handle high cycle volumes.
Laboratory Pneumatic Boards
Supplies stable low-pressure air to analytical instruments, using the metal bowl for solvent resistance and the automatic drain for unattended operation.
Is the Airtac GAC F.R.L. Unit GAC400C15ALWK the Right Air-Prep Unit?
Choose this configuration when a machine requires low-pressure operation capped at 0.4 MPa, as the L type is the wrong part if the application might ever need standard pressures up to 0.9 MPa. The 5 um element traps far finer particles than the 40 um standard, suiting precision valves or instrument air at the cost of more frequent element service. If the downstream line must remain oil-free, omit the lubricator and choose a filter-regulator instead. The metal bowl suits harsher environments, and replacement spares follow the body-port suffix: 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, exactly double the GAC300's 3000 L/min envelope, providing clear sizing headroom. Because the L type tops out at 0.4 MPa, it provides only 44% of the Standard type's 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 GAC400C15ALWK FAQ
This lower-pressure unit regulates from 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 operates from -5 to 70 C, weighs 2390 g, and pairs a 100 cc drain bowl with a 185 cc oil bowl. The recommended lubricant is ISO VG 32.
The K indicates a reverse-flow (reflux) valve is attached. The catalogue depicts this as a distinct pneumatic symbol with full details provided on its own page; it is an ordering difference that modifies the unit's internal air path.
