About the Airtac GAC F.R.L. Unit GAC40010ALK
Delivering cleaned, regulated and lubricated air for pneumatic machinery, the GAC40010ALK is a complete F.R.L. combination pairing a filter, regulator and lubricator on a single L-shape bracket. This assembly features a 3/8in port and a standard 40 um element. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of the pressure control mechanism.
Configured for low-pressure duties, the regulator operates within a 0.15-0.4 MPa (20-58 psi) range. The unit carries an automatic drain to clear condensate without operator intervention and includes a reverse-flow (reflux) valve, which the catalogue illustrates as a separate pneumatic symbol. A circular gauge is fitted, reading MPa/psi for the default PT thread, allowing operators to monitor 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 GAC40010ALK Is Used
Low-Force Assembly Presses
Feeds controlled air at 0.4 MPa to light-duty pneumatic presses used for riveting or press-fitting delicate electronic connectors without applying excessive force.
Carton Erector Lines
Prepares air for packaging machinery where lower actuator pressure prevents crushing cardboard cartons during the folding and sealing processes.
Laboratory Gas Handling
Conditions supply air for sensitive pneumatic test benches, utilizing the 40 um element and auto drain to maintain clean, moisture-free air for precision instruments.
Is the Airtac GAC F.R.L. Unit GAC40010ALK the Right Air-Prep Unit?
Choose this 2390 g assembly when a machine requires stable low-pressure control up to 0.4 MPa rather than the standard 0.9 MPa ceiling. The 100 cc condensate bowl and 185 cc oil sump dictate the maintenance interval, offering a larger fluid capacity than the GAC300's 60 cc and 98 cc bowls, meaning fewer interventions. If the downstream line must remain completely free of oil, omit the lubricator and select a dedicated filter-regulator instead. Should a component fail, individual spares are available using the GAF400-10, GAR400-10 and GAL400-10 designations.
The catalogue flow curve for the GAC400 is plotted to 6000 L/min at 0.7 MPa inlet, providing a sizing envelope that is double the GAC300's 3000 L/min capacity. Keep in mind that the 0.4 MPa upper limit is 44% of the standard 0.9 MPa ceiling, so verify your machinery never requires more pressure before specifying this lower-pressure type.
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 GAC40010ALK FAQ
This lower-pressure type 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 in temperatures from -5 to 70 C, weighs 2390 g, and features a 100 cc drain bowl alongside a 185 cc oil bowl. The recommended lubricant is ISO VG 32.
The K signifies that a reverse-flow (reflux) valve is fitted to this assembly. The official AirTAC catalogue presents this component as a distinct pneumatic symbol with specific details located on its own dedicated page.
