Airtac GAC F.R.L. Unit GAC400C15LNWK
The AirTAC Airtac GAC F.R.L. Unit GAC400C15LNWK 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 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi).

About the Airtac GAC F.R.L. Unit GAC400C15LNWK
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC GAC400C15LNWK F.R.L. combination integrates a filter, regulator and lubricator on a single L-shape bracket with quick mounting clamps. The 1/2in port serves machines needing substantial airflow, while the 5 um element traps fine particles before they reach precision valves. Because the lubricator sits downstream of the regulator, oil mist is added last, preventing fouling of the regulating seat.
This specific configuration carries a lower pressure type operating range of 0.15-0.4 MPa (20-58 psi) and ships without a gauge, though a 1/4in gauge connection is available if you need to add one later. The metal bowl equips the unit for harsher industrial settings, and the assembly weighs 2390 g, requiring a solid frame mount rather than tubing support. A reverse-flow (reflux) valve is fitted, shown in the catalogue as a distinct pneumatic symbol.

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 GAC400C15LNWK Is Used
Precision CNC Tooling
Feeds clean, finely filtered 5 um air to sensitive pneumatic tool changers and actuators on CNC machining centers requiring stable low-pressure control.
Flow Wrapper Sealing
Conditions air for heated sealing jaws and flow-wrapping equipment where precise low-pressure regulation prevents crushing delicate film packaging.
Laboratory Dispensing
Regulates air for chemical dosing and fluid dispensing stations that depend on a 0.4 MPa ceiling to protect sensitive glass and pneumatic metering components.
Is the Airtac GAC F.R.L. Unit GAC400C15LNWK the Right Air-Prep Unit?
Choose this 1/2in port model when your application demands the 5 um fine filtration grade and a lower pressure ceiling of 0.4 MPa, rather than the standard 0.9 MPa range. The metal bowl offers durability where PC or nylon might be unsuitable, and the semi-auto and manual drain pairing gives operators direct control over the 100 cc condensate bowl. Since no gauge is supplied, the set pressure cannot be read without adding one to the 1/4in connection. If the downstream line must remain completely oil-free, omit the lubricator and choose a dedicated filter-regulator instead. For maintenance, the assembly uses GAF400-15, GAR400-15 and GAL400-15 spares. Stepping up from a GAC300 increases the plotted flow envelope from 3000 to 6000 L/min at 0.7 MPa inlet, doubling the available sizing curve, and the L-type pressure ceiling of 0.4 MPa is 44% of the standard 0.9 MPa maximum.
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 GAC400C15LNWK FAQ
This lower-pressure type 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, uses a 100 cc drain bowl and a 185 cc oil bowl with ISO VG 32 lubricant, and weighs 2390 g.
The N after the port indicates no gauge is supplied, though a 1/4in connection exists if you wish to fit one. The K denotes that a reverse-flow (reflux) valve is attached, which the catalogue details as a separate pneumatic symbol on its own page.
