Airtac GAFR Adjustable Filter Regulator GAFR300N15ALNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300N15ALNW 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 GAFR300N15ALNW
The GAFR300N15ALNW is a filter and pressure regulator combined into one body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/2in port with a nylon bowl, and its 5 um element traps fine particles for sensitive downstream equipment.
This lower-pressure model regulates from 0.15 to 0.4 MPa (20-58 psi), with a maximum supply of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The automatic drain clears condensate without manual attention, and the unit weighs 500 g with a 60 cc drain bowl.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR300 is 1/8" if you add one. This unit filters and regulates only; it does not add lubrication.

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 GAFR300N15ALNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves that need clean, regulated air at a consistent lower pressure, with the 5 um element protecting fine internal passages.
Automated assembly station
Supply a compact assembly station with a single 1/2in line, where the automatic drain reduces maintenance visits and the lower pressure range suits delicate gripping operations.
Test bench air supply
Provide a stable lower-pressure air source for a lab test bench, where the nylon bowl offers visibility of condensate and the included bracket secures the 500 g unit to a frame.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300N15ALNW the Right Air-Prep Unit?
Choose the GAFR300 body for 1/2in porting with a 60 cc condensate bowl, a middle step between the smaller GAFR200 and the larger GAFR400. The nylon bowl is a build choice with the same 1.0 MPa max and -5 to 70 C limits as PC or metal versions, so confirm compatibility for aggressive environments. The automatic drain suits unattended or wet lines, while the included bracket simplifies mounting; the 5 um element offers finer filtration than the standard 40 um but requires more frequent service. No gauge is fitted, so the 1/8in gauge connection is ready for a field-installed unit, and the PT thread matches the MPa/psi scale. If oil is needed downstream, order the matching GAFC300-15 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range.
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 GAFR300N15ALNW FAQ
The GAFR300N15ALNW is a filter & regulator with a 1/2in port, nylon bowl, automatic drain, and 5 um element. Pressure range is 0.15-0.4 MPa (20-58 psi), max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C. It weighs 500 g with a 60 cc drain bowl and has no gauge fitted.
The L type code limits regulation to 0.15-0.4 MPa (20-58 psi), which suits applications needing a capped low pressure; if more is ever needed, this is the wrong part. The N after the port means no gauge is supplied, so the 1/8in gauge connection is available for adding one later to read the set pressure.
