Airtac GAFR Adjustable Filter Regulator GAFR30015LJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015LJW is a genuine two-in-one filter & regulator — a diversion-type water/particulate filter and a balanced pressure regulator built into ONE body. It has 1/2" ports, a 5 µm filter element and regulates 0.15 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR30015LJW
The GAFR30015LJW is a filter and regulator combined into one body, so it cleans incoming air and sets a steady outlet pressure without needing a separate filter plus regulator pair. This 1/2in model is the lower-pressure version, regulating from 0.15 to 0.4 MPa (20-58 psi), and it ships with a 5 um element for trapping fine particles.
Its diversion structure spins the airflow to throw liquid water and solid debris into the 60 cc condensate bowl, while the pressed-in self-locking knob resists drift from vibration. Weighing 500 g, this unit suits a compact machine frame where a lighter build is preferred over a heavier two-part assembly.

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 GAFR Adjustable Filter Regulator GAFR30015LJW Is Used
Precision valve control
Feed a bank of precision pneumatic valves that need a stable, low supply pressure. The 5 um element protects fine internal passages, and the lower 0.4 MPa ceiling prevents over-pressuring sensitive actuators.
Lab air bench
Supply a laboratory test bench where instruments require clean, low-pressure air. The 60 cc bowl handles condensate from a moderately wet line, and the manual drain lets an operator purge it between test runs.
Compact assembly jig
Mount this unit on a small assembly jig that uses a single 1/2in line. The 500 g weight is light enough for a panel bracket, and the self-locking knob keeps the set pressure steady despite machine vibration.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015LJW the Right Air-Prep Unit?
Choose the GAFR300 body when you need a 1/2in port with a 60 cc drain bowl and a 3500 L/min flow curve at 0.7 MPa inlet. The L code sets a lower 0.15-0.4 MPa (20-58 psi) band, which is ideal for delicate circuits, but confirm the machine never needs more than 0.4 MPa. This model has no mounting bracket (J), so plan for a panel mount or an existing bracket, and the 5 um element (W) suits precision valves or instrument air, though it will need more frequent service than a 40 um element. The PT thread gives an MPa/psi gauge scale, and the semi-auto plus manual drain means you can purge the bowl manually or let it dump when pressure drops. If the line needs oil downstream, order the matching GAFC300-15 combination instead. With a 1.0 MPa max supply, the regulated band tops out at 0.4 MPa, leaving about 0.6 MPa of headroom above the setpoint for stable regulation.
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
- ✓ Bracket kept or removed (J); add a lubricator = GAFC
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, gauge/knob accessible.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure with the pressed-in self-locking knob; pull to adjust, press to lock.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 g unit on its bracket, not on the tubing.
This is a filter and regulator only — it delivers filtered, pressure-set air with no added oil. If a downstream tool needs lubrication, add a separate lubricator or order the GAFC300-15 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR30015LJW FAQ
The GAFR30015LJW is a filter & regulator with a 1/2in port, a 0.15-0.4 MPa (20-58 psi) regulating range, a 1.0 MPa (145 psi) max pressure, and a 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C, has a 60 cc drain bowl, and weighs 500 g. The 5 um element filters fine particles, and the unit has a semi-auto plus manual drain.
The L code sets the regulating range to 0.15-0.4 MPa (20-58 psi) instead of the standard 0.15-0.9 MPa. This is for applications that need a low, stable pressure and should never exceed 0.4 MPa. If your machine may ever need more than 0.4 MPa, the L type is the wrong choice and you should select a standard S type instead.
