About the Airtac GAC F.R.L. Unit GAC400C10LWK
Delivering cleaned, regulated and lubricated air for pneumatic systems, this GAC400C10LWK combines a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. The 3/8in port pairs with a 5 um element to trap fine particles before they reach sensitive valves. Because the lubricator sits downstream of the regulator, oil mist is added last, preventing fouling of the regulating seat.
This variant features a robust metal bowl and operates on the lower pressure range of 0.15-0.4 MPa (20-58 psi). A circular gauge reading MPa/psi is fitted for the default PT thread, allowing operators to monitor the set pressure directly. The reverse-flow (reflux) valve is fitted, shown as a separate pneumatic symbol in the catalogue, and the 100 cc drain bowl paired with a 185 cc oil bowl dictates the maintenance interval.

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 GAC400C10LWK Is Used
Precision Valve Arrays
Feeds clean, finely filtered 5 um air to low-pressure pneumatic valve manifolds in coordinate measuring machines where standard 40 um filtration is insufficient.
Low-Pressure Packaging
Supplies steady 0.15-0.4 MPa lubricated air to delicate sealing jaws and clamping actuators in flow-wrapping equipment to prevent delicate film tearing.
Laboratory Pneumatics
Conditions air for sensitive laboratory dosing pumps and fluid handling actuators that require stable low-pressure operation and consistent oil mist delivery.
Is the Airtac GAC F.R.L. Unit GAC400C10LWK the Right Air-Prep Unit?
Choose this 2390 g unit for medium-duty air preparation requiring fine filtration and low-pressure regulation. The 5 um element provides higher purity than the standard 40 um grade, ideal for instrument air, though it requires more frequent element replacement. The metal bowl suits harsher industrial environments, while the semi-auto and manual drain options give operators flexibility in condensate management. If the downstream line must remain completely oil-free, omit the lubricator and select a filter-regulator instead. Replacement spares follow the body-port suffix exactly: GAF400-10, GAR400-10 and GAL400-10.
When sizing, the catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, exactly double the 3000 L/min envelope of the GAC300. Keep in mind that the 0.4 MPa ceiling is 44% of the Standard type's 0.9 MPa maximum, so verify your machinery never requires a higher operating pressure before specifying this L-type unit.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAC400C10LWK FAQ
This lower-pressure type unit regulates from 0.15-0.4 MPa (20-58 psi) and carries a max pressure of 1.0 MPa (145 psi) with a 1.5 MPa (215 psi) proof pressure. Operating temperature is -5 to 70 C using ISO VG 32 lubricant. It features a 3/8in port, a 100 cc drain bowl, a 185 cc oil bowl, and weighs 2390 g.
The K indicates that a reverse-flow (reflux) valve is attached to the assembly. The official AirTAC catalogue displays this as a distinct pneumatic symbol located on its own dedicated page, and specific functional details should be confirmed from that datasheet.
