Airtac GAC F.R.L. Unit GAC40015ASNW
The AirTAC Airtac GAC F.R.L. Unit GAC40015ASNW 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 - 0.9 MPa (20 - 130 psi).

About the Airtac GAC F.R.L. Unit GAC40015ASNW
Delivering cleaned, regulated and lubricated air for mid-size pneumatics, this AirTAC GAC40015ASNW conditions supply through a 1/2in port. It pairs a 5 um filter element with a standard pressure regulator operating at 0.15-0.9 MPa (20-130 psi). Because the 5 um grade traps far finer particulate than the standard 40 um mesh, it suits precision valves and instrument air, though the tighter media requires more frequent element service. The assembly integrates a filter, regulator and lubricator pre-plumbed on a single L-shape bracket with quick mounting clamps, eliminating inter-unit tubing leaks.
Air passes through the filter first, then the regulator, with oil mist added last so the internal regulator seat never fouls. This specific configuration uses a PC bowl and an automatic drain that clears condensate without an operator, which is decisive for unattended or wet lines. The 100 cc condensate bowl and 185 cc oil reservoir dictate the maintenance interval, setting a service rhythm that balances capacity against physical size. At 2390 g, the unit needs a proper panel or frame mount rather than support from the piping.

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 GAC40015ASNW Is Used
CNC Tool Changers
Supplies clean, oil-misted air to pneumatic tool change cylinders, relying on the 5 um element to protect tight tolerances from particulate scoring.
Flow Wrappers
Feeds the 1/2in air header of a continuous motion wrapper, maintaining steady pressure for sealing jaws while the auto drain handles condensate.
Textile Looms
Conditions air for multi-station rapier looms where the automatic drain prevents moisture spitting onto yarn guides during long unattended shifts.
Is the Airtac GAC F.R.L. Unit GAC40015ASNW the Right Air-Prep Unit?
Choose this 1/2in body when a machine demands fine 5 um filtration alongside standard 0.15-0.9 MPa (20-130 psi) regulation. The automatic drain suits wet compressors or remote installations where manual draining is impractical. Since no gauge is supplied, the set pressure cannot be read without adding one later to the 1/4in gauge connection. The thread is PT, meaning any added gauge should read MPa/psi. If the downstream line must stay oil-free, omit the lubricator and choose a filter-regulator instead. For maintenance, the three units are separately orderable as GAF400-15, GAR400-15 and GAL400-15. Stepping down to the GAC300 halves the plotted flow envelope to 3000 L/min at 0.7 MPa inlet, whereas this GAC400 reaches 6000 L/min, giving exactly a 2x flow-envelope step up for sizing larger duties.
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 GAC40015ASNW FAQ
This model operates at 0.15-0.9 MPa (20-130 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. It features a 100 cc drain bowl and a 185 cc oil bowl, uses ISO VG 32 lubricant, and weighs 2390 g.
The N in the ordering code means no gauge is supplied from the factory. To read the set pressure, an operator must add a circular gauge to the 1/4in gauge connection on the regulator body, ensuring the scale matches the PT thread standard of MPa/psi.
