About the Airtac GAC F.R.L. Unit GAC400C15ALW
Delivering cleaned, regulated and lubricated air for demanding pneumatics, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in ported body carries a 5 um element to trap fine particles before they reach precision valves, operating within the lower 0.15-0.4 MPa (20-58 psi) pressure band.
Air passes through the filter first, then the regulator, with oil mist added last so the regulator seat stays clean. The metal bowl equips this 2390 g assembly for rugged environments, while the automatic drain clears condensate from the 100 cc bowl without an operator. A circular gauge reading MPa/psi is fitted for the default PT thread, letting technicians verify the set pressure directly.

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 GAC400C15ALW Is Used
Precision Valve Manifolds
Feeds instrument air to sensitive solenoid valve banks, leveraging the 5 um element to prevent sticking and ensure accurate shifting in packaging machinery.
Low-Force Assembly Presses
Regulates down to the 0.15-0.4 MPa range for delicate pneumatic presses that assemble electronics, preventing damage to fragile components.
Automated Carton Sealers
Supplies steady, lubricated air to high-speed carton sealing actuators, with the automatic drain handling condensate during continuous daily runs.
Is the Airtac GAC F.R.L. Unit GAC400C15ALW the Right Air-Prep Unit?
Choose this model for 1/2in lines requiring a low 0.15-0.4 MPa (20-58 psi) operating range and fine 5 um filtration. The metal bowl suits harsher industrial settings compared to standard PC or nylon options. Because the automatic drain handles condensate evacuation independently, it is well suited for unattended stations. If the downstream line must remain completely oil-free, omit the lubricator and choose a filter-regulator instead. The three constituent units are separately orderable as GAF400-15, GAR400-15 and GAL400-15, meaning a clogged element does not require replacing the whole assembly. Stepping up to this body gives a flow envelope plotted to 6000 L/min at 0.7 MPa inlet, which is double the 3000 L/min envelope of the GAC300. Keep in mind that 0.4 MPa is 44% of the 0.9 MPa ceiling found on standard type units, so verify your machinery never requires higher pressure.
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 GAC400C15ALW FAQ
This lower-pressure type unit 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). It features a 1/2in port, a 5 um element, and a temperature range of -5 to 70 C. The drain bowl holds 100 cc, the oil bowl holds 185 cc, the recommended lubricant is ISO VG 32, and the unit weighs 2390 g.
The 5 um element (denoted by the W code) traps far finer particles than the standard 40 um filter, making it ideal for protecting precision valves and instrument air systems, though it requires more frequent element service. The metal bowl (C code) is selected for rugged environments where chemical or impact resistance might be a concern, sharing the exact same 1.0 MPa max pressure rating as the PC and nylon alternatives.
