Airtac GAC F.R.L. Unit GAC400N10LNK
The AirTAC Airtac GAC F.R.L. Unit GAC400N10LNK 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 GAC400N10LNK
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. The 3/8in ported body carries a 40 um element and a nylon bowl, operating specifically within the lower 0.15-0.4 MPa (20-58 psi) pressure band. Weighing 2390 g, the assembly uses quick mounting clamps to eliminate inter-unit tubing, and the 100 cc condensate bowl paired with a 185 cc oil reservoir sets the maintenance interval for the machine.
Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of the pressure control mechanism. This specific SKU ships without a pressure gauge, but features a 1/4in gauge connection for adding one if visual monitoring becomes necessary. A semi-auto and manual drain pair is fitted to manage condensate, and the assembly includes a reverse-flow (reflux) valve, which the catalogue depicts as a separate pneumatic symbol on its own page.

Where the Airtac GAC F.R.L. Unit GAC400N10LNK Is Used
Low-Force Textile Looms
Feeds sensitive weaving actuators where high pressure would damage delicate fabric threads, utilizing the 0.15-0.4 MPa regulation range.
Laboratory Pneumatic Slides
Conditions air for precision positioners on testing benches, relying on the 40 um element to protect delicate instrument valves from particulate ingress.
Light-Duty Carton Sealers
Provides steady low-pressure air to folding and sealing cylinders, with the 185 cc oil bowl ensuring consistent lubrication over long production runs.
Is the Airtac GAC F.R.L. Unit GAC400N10LNK the Right Air-Prep Unit?
Choose this model when a 3/8in line requires strictly low-pressure regulation up to 0.4 MPa; if the application might ever demand standard 0.9 MPa output, the L type is the wrong choice. The nylon bowl offers a lightweight alternative to the standard PC or metal options, sharing the exact same 1.0 MPa maximum and -5 to 70 C thermal limits. Since no gauge is supplied, operators must add one to the 1/4in port to read the set pressure. If the downstream line must remain totally oil-free, omit the lubricator and choose a filter-regulator instead. For future maintenance, the assembly breaks down into GAF400-10, GAR400-10 and GAL400-10 spares. The 0.4 MPa ceiling is 44% of the standard 0.9 MPa maximum, capping the available output force for downstream actuators.
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 GAC400N10LNK FAQ
This lower-pressure unit regulates from 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). It operates in temperatures from -5 to 70 C, features a 40 um element, and uses ISO VG 32 lubricant. The drain bowl holds 100 cc, the oil bowl holds 185 cc, and the unit weighs 2390 g.
The N before the port designates a nylon bowl material, while the L indicates the lower 0.15-0.4 MPa pressure range. The K signifies that a reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol. Additionally, an N after the port means no gauge is supplied, though a 1/4in connection is available for adding one.
