Airtac GAC F.R.L. Unit GAC400C10ALN
The AirTAC Airtac GAC F.R.L. Unit GAC400C10ALN 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 3/8" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC400C10ALN
Delivering cleaned, regulated and lubricated air for pneumatic systems, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The metal bowl model is equipped with a 3/8in port, a 40 um element and an automatic drain that clears condensate without an operator. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling during pressure control.
This lower-pressure type regulates between 0.15-0.4 MPa (20-58 psi), making it suitable for low-force actuator circuits. No gauge is supplied, but the body features a 1/4in gauge connection if monitoring is added later. The 100 cc condensate bowl and 185 cc oil reservoir drive the maintenance interval, while the 2390 g mass requires a firm panel or frame mount rather than tubing support.

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 GAC400C10ALN Is Used
Low-Force Assembly Jigs
Feeds light-touch pneumatic grippers and clamps on electronic assembly fixtures where actuator forces must stay below 0.4 MPa.
Laboratory Test Benches
Conditions supply air for sensitive metering valves and low-pressure cylinder drives, adding downstream oil mist for moving parts.
Textile Machinery
Prepares air for low-tension fabric handling cylinders, using the automatic drain to handle humid plant environments unattended.
Is the Airtac GAC F.R.L. Unit GAC400C10ALN the Right Air-Prep Unit?
Choose this 3/8in GAC400 unit when a low-pressure circuit demands an automatic condensate discharge without operator intervention. The metal bowl offers a robust build for industrial environments, and the 40 um element balances particle capture with service life. If your downstream line must remain completely oil-free, omit the lubricator and select a standalone filter-regulator instead. For maintenance, the assembly accepts individual GAF400-10, GAR400-10 and GAL400-10 replacement units. Stepping up to the GAC500 body increases the plotted flow envelope from 6000 L/min to 7000 L/min at 0.7 MPa inlet. Keep in mind that 0.4 MPa is about 44% of the Standard type's 0.9 MPa ceiling.
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 GAC400C10ALN FAQ
This lower-pressure type 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). The temperature range is -5 to 70 C. It features a 100 cc drain bowl, a 185 cc oil bowl, a 40 um element, and weighs 2390 g. The recommended lubricant is ISO VG 32.
The N in the product code indicates no gauge is supplied. The unit has a 1/4in gauge connection on the body, allowing you to install a separate PT-thread gauge reading in MPa/psi to monitor your specific 0.15-0.4 MPa setpoint.
