Airtac GAFR Adjustable Filter Regulator GAFR30015ALW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015ALW 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 GAFR30015ALW
The GAFR30015ALW is a filter and regulator combined into a single body, so incoming air is cleaned and then set to a steady outlet pressure without needing separate components. This lower-pressure model operates from 0.15 to 0.4 MPa (20-58 psi) and comes with a 5 um element for finer filtration.
Its 1/2in port and 500 g mass place it in the GAFR300 size class, which suits medium-flow lines where a compact footprint matters. The automatic drain clears condensate from the 60 cc bowl without manual attention, and the circular gauge with MPa/psi scale lets you verify the set pressure at a glance.

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 GAFR30015ALW Is Used
Precision valve control
Feed a bank of precision pneumatic valves that need clean, regulated air at a stable lower pressure, with the 5 um element protecting fine internal passages.
Medium conveyor line
Supply a medium-duty conveyor drive with filtered air at a consistent 0.15-0.4 MPa, while the automatic drain handles condensate from humid plant air.
Test bench air supply
Provide a clean, low-pressure air source for bench testing components, where the 60 cc bowl and 500 g body fit neatly into a compact test rig.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015ALW the Right Air-Prep Unit?
Choose the GAFR300 body when you need a 1/2in port and a 60 cc condensate bowl, stepping up from the GAFR200's 25 cc bowl if your line has more moisture. The PC bowl is the standard build, while the 5 um element traps finer particles than the 40 um default for sensitive downstream equipment. The automatic drain (A) suits wet or unattended lines, and the included mounting bracket simplifies panel installation. The L-type regulation tops out at 0.4 MPa, so verify your system never needs more than that. 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, giving you ample inlet margin 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 GAFR30015ALW FAQ
Working pressure range is 0.15-0.4 MPa (20-58 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Operating temperature is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 500 g.
The L code sets regulation from 0.15 to 0.4 MPa instead of the standard 0.15-0.9 MPa. This suits applications needing a limited, precise lower pressure band, but it cannot deliver higher outlet pressures if your process requirements change.
