Airtac GAC F.R.L. Unit GAC40015ALNK
The AirTAC Airtac GAC F.R.L. Unit GAC40015ALNK 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 GAC40015ALNK
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 assembly features a 40 um element and operates specifically within the lower 0.15-0.4 MPa (20-58 psi) pressure band. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling during pressure modulation.
Weighing 2390 g, the unit requires a solid panel or frame mount rather than tubing support. It carries a 100 cc condensate bowl paired with a 185 cc oil reservoir, extending the interval between maintenance interventions. This variant ships without a gauge but retains a 1/4in gauge connection for future installation, while the automatic drain clears liquid without manual intervention.

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 GAC40015ALNK Is Used
Low-Pressure Packaging Lines
Feeds delicate pneumatic clamps and pick-and-place actuators on flow-wrapping equipment that require a stable, regulated 0.4 MPa supply.
Textile Manufacturing
Conditions air for looms and spinning frames where consistent low-pressure air drives weft insertion nozzles without stressing fine yarns.
Laboratory Automation
Prepares instrument air for sensitive pneumatic test rigs and fluid dispensing robots that cannot tolerate pressure spikes above 0.4 MPa.
Is the Airtac GAC F.R.L. Unit GAC40015ALNK the Right Air-Prep Unit?
Choose this GAC400 configuration for medium-scale air preparation where downstream equipment operates strictly below 0.4 MPa. The automatic drain is decisive for wet lines or unattended machinery, emptying the 100 cc bowl independently. If your application requires completely oil-free output downstream, you must omit the lubricator and select a dedicated filter-regulator instead. The reverse-flow (reflux) valve is fitted here, shown as a separate pneumatic symbol in the catalogue. Replacement components follow the 400-15 suffix exactly: order GAF400-15, GAR400-15 and GAL400-15 individually. Stepping up to this body yields a significant capacity increase, as its 6000 L/min plotted flow envelope at 0.7 MPa inlet is double the 3000 L/min curve of the GAC300. Keep in mind that 0.4 MPa is 44% of the 0.9 MPa standard ceiling, so confirm your machinery will never require higher pressure before specifying this lower-pressure type.
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 GAC40015ALNK FAQ
This lower-pressure type unit 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, uses a 40 um element, and weighs 2390 g. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the recommended lubricant is ISO VG 32.
The N in the product code indicates no gauge is supplied. The body features a 1/4in gauge connection, allowing operators to install a specific PT-thread gauge reading in MPa/psi if downstream pressure monitoring is required for the application.
