Airtac GAC F.R.L. Unit GAC400N15LN
The AirTAC Airtac GAC F.R.L. Unit GAC400N15LN 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 GAC400N15LN
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket. The 1/2in port pairs with a 40 um element, while the lower-pressure type restricts the operating band to 0.15-0.4 MPa (20-58 psi). Because the lubricator sits downstream of the regulator, oil mist never fouls the pressure-control seat.
The nylon bowl equips this unit for environments where condensate visibility is less critical than structural resilience, and no pressure gauge is supplied from the factory. A 1/4in gauge connection remains available if operators later need to read the set pressure. Condensate is managed by a paired semi-auto and manual drain, dumping liquid on pressure drops or on demand.

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 GAC400N15LN Is Used
Textile Machinery
Feeds low-pressure loom cylinders where a 0.4 MPa ceiling prevents fabric damage while the 100 cc drain bowl captures lint and moisture.
Carton Folding Lines
Conditions air for folding actuators that rely on steady, low-force clamping, utilizing the 185 cc oil bowl to maintain consistent misting.
Lab Pneumatic Stations
Prepares supply for sensitive test fixtures requiring gentle actuation, with the nylon bowl offering resilience against accidental bench impacts.
Is the Airtac GAC F.R.L. Unit GAC400N15LN the Right Air-Prep Unit?
Choose this 2390 g assembly for mid-capacity air preparation, stepping down from the GAC500 which offers a 7000 L/min plotted flow envelope at 0.7 MPa inlet compared to the 6000 L/min curve printed for this body. If your machine demands standard pressure up to 0.9 MPa, select the S type instead of this L variant, as the 0.4 MPa ceiling will starve high-force actuators. Should the downstream line require absolutely oil-free air, omit the lubricator and choose a dedicated filter-regulator. Replacement spares share the 400-15 suffix: GAF400-15, GAR400-15 and GAL400-15. Note that the 0.4 MPa upper limit is 44% of the standard 0.9 MPa ceiling, so confirm your actuators can develop the required force before ordering.
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 GAC400N15LN FAQ
This lower-pressure type operates at 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). The temperature range is -5 to 70 C, and the recommended lubricant is ISO VG 32. It features a 100 cc drain bowl, a 185 cc oil bowl, and weighs 2390 g.
The N in the ordering code indicates that no circular gauge is supplied, meaning the set pressure cannot be read without adding one. The unit uses PT threads, and if a gauge is added later, it should match the 1/4in connection and read in MPa/psi to align with the default scale.
