Airtac GAC F.R.L. Unit GAC400N15LNK
The AirTAC Airtac GAC F.R.L. Unit GAC400N15LNK 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 GAC400N15LNK
Delivering cleaned, regulated and lubricated air for demanding pneumatic setups, this AirTAC unit combines a filter, regulator and lubricator on a single L-shape bracket. The 1/2in ported body operates at 0.15-0.4 MPa (20-58 psi) and uses a 40 um element to strip moisture and solid grain before the air reaches downstream moving parts. Because the lubricator sits last in the sequence, oil mist is introduced downstream of the regulator seat, preventing fouling of the pressure control mechanism.
Weighing 2390 g, this assembly requires a solid panel or frame mount rather than relying on the connected tubing for physical support. The nylon bowl provides a clear view of the fluid levels, while the semi-auto and manual drain pairing clears the 100 cc condensate sump on every pressure drop or on operator demand. No pressure gauge is supplied, but the body features a 1/4in connection should you need to add one to monitor the set pressure.

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 GAC400N15LNK Is Used
Textile Machinery
Feeds loom and spinning frames where a low-pressure 1/2in air line drives delicate yarn guides and clamping cylinders without overstressing the fabric.
Carton Erectors
Provides steady 0.4 MPa air to folding and sealing actuators, ensuring consistent carton forming on high-speed packaging lines.
Lab Pneumatic Banks
Conditions instrument air for analytical equipment and low-force test rigs that require a regulated, lubricated supply below 0.4 MPa.
Is the Airtac GAC F.R.L. Unit GAC400N15LNK the Right Air-Prep Unit?
Choose this GAC400 body when a machine needs a mid-range 1/2in air supply, stepping up from the GAC300 which has a 3000 L/min plotted flow envelope at 0.7 MPa inlet to this unit's 6000 L/min curve. The nylon bowl is suited for standard environments, though buyers should confirm material compatibility for aggressive chemical surroundings. If the downstream line must remain oil-free, you must omit the lubricator and choose a filter-regulator instead, as this unit actively adds an oil mist.
Spares are available as GAF400-15, GAR400-15 and GAL400-15, meaning a damaged bowl or clogged element does not require replacing the whole assembly. Note that the lower-pressure type caps the ceiling at 0.4 MPa, which is 44% of the standard 0.9 MPa maximum, so if the machine may ever need more pressure the L type is the wrong part.
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 GAC400N15LNK FAQ
This F.R.L. combination has a 1/2in port and a 40 um element. The pressure range is 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 from -5 to 70 C, weighs 2390 g, has a 100 cc drain bowl and a 185 cc oil bowl, and uses ISO VG 32 lubricant.
The N in the code means no gauge is supplied, so the set pressure cannot be read without adding one to the 1/4in gauge connection. The K indicates a reverse-flow (reflux) valve is fitted, which the catalogue shows as a separate pneumatic symbol with details on its own page.
