Airtac GAC F.R.L. Unit GAC400N15AL
The AirTAC Airtac GAC F.R.L. Unit GAC400N15AL 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 1/2" ports, a 40 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC400N15AL
Delivering cleaned, regulated and lubricated air for pneumatic systems, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. The 1/2in port serves mid-range machinery, and the 40 um element captures solid particulates before they reach downstream valves. Air flows through the filter first, then the regulator, and finally the lubricator, ensuring oil mist is added downstream so the regulator seat never fouls.
Configured for low-pressure duties, the regulator operates within a 0.15-0.4 MPa (20-58 psi) range. The nylon bowl houses an automatic drain that expels condensate without an operator, holding up to 100 cc of water, while the 185 cc oil reservoir sets the lubrication interval. 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 GAC400N15AL Is Used
Low-Pressure Packaging
Feeds delicate pneumatic grippers and sealing jaws on flow-wrapping lines where actuator forces must stay below 0.4 MPa to prevent crushing product.
Textile Machinery
Conditions air for looms and spinning frames that rely on gentle, consistent cylinder pressure to handle fragile yarns without snags.
Laboratory Automation
Supplies metered, lubricated air to low-force analytical instruments and sample-handling robots requiring stable, sub-0.4 MPa operation.
Is the Airtac GAC F.R.L. Unit GAC400N15AL the Right Air-Prep Unit?
Choose this 2390 g assembly for machines requiring a stable, lower outlet ceiling of 0.4 MPa; if the equipment might ever demand higher force, the L type is the wrong part. The nylon bowl suits standard plant environments, and the automatic drain is decisive for unattended or wet lines. Because the lubricator introduces oil mist downstream, select a separate filter-regulator if the application requires strictly dry, oil-free air. Should the element clog or a bowl crack, the three units are separately orderable as GAF400-15, GAR400-15 and GAL400-15. Stepping down to the GAC300 reduces the plotted flow envelope from 6000 L/min to 3000 L/min at 0.7 MPa inlet, whereas moving up to the GAC500 keeps a similar flow but changes the port. The 0.4 MPa upper limit is 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 GAC400N15AL FAQ
This lower-pressure type regulates from 0.15-0.4 MPa (20-58 psi) against a max 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 using ISO VG 32 lubricant.
The A in the ordering code specifies an automatic drain that clears condensate from the 100 cc nylon bowl without manual intervention, making it ideal for unattended stations. The fitted circular gauge reads in MPa/psi to match the default PT thread.
