Airtac GAFR Adjustable Filter Regulator GAFR300N15LNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300N15LNW 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 GAFR300N15LNW
The GAFR300N15LNW is a filter & regulator with both functions in one body, saving rail space and reducing leak points versus separate units. It handles a 1/2in port with a lower pressure range of 0.15-0.4 MPa (20-58 psi) and uses a 5 um element for finer filtration.
Its nylon bowl holds 60 cc of condensate, and the unit weighs 500 g. The diversion structure spins incoming air to separate liquid water and solid particles into the bowl. This model has no gauge, but the 1/8in gauge connection is ready for one.

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 GAFR300N15LNW Is Used
Precision valve control
Feed a precision pneumatic valve with the 5 um element and lower 0.4 MPa range for consistent actuation in a controlled manufacturing cell.
Bench test rig
Use on a lab bench or test rig where a compact 500 g unit with a 1/2in port provides clean, low-pressure air for experiments or calibration.
Light packaging line
Install on a light packaging line to filter and regulate air for low-force grippers or sensors, with the semi-auto drain for periodic maintenance.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300N15LNW the Right Air-Prep Unit?
Choose the GAFR300 body for 1/2in ports and a 500 g mass, a step up from the GAFR200's 25 cc bowl. The nylon bowl suits environments where a clear PC bowl is not preferred. This unit ships with both semi-auto and manual drains, giving you flexible condensate removal. The L type tops out at 0.4 MPa, so if your machine may need more pressure, select the standard S type instead. The mounting bracket is included, and the 5 um element traps finer particles than the standard 40 um, though it may need more frequent service. The PT thread matches standard gauge scales. For lines needing oil downstream, order the matching GAFC300-15 combination. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this unit's 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 GAFR300N15LNW FAQ
The GAFR300N15LNW is a filter & regulator with a 1/2in port, working pressure range of 0.15-0.4 MPa (20-58 psi), max pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). It operates in -5 to 70 C temperatures, has a 60 cc drain bowl, and weighs 500 g. The element grade is 5 um.
The L type is designed for applications that only need up to 0.4 MPa (58 psi), such as delicate low-force operations. It provides finer adjustment within this band. If your system may require higher pressure, you would need the standard S type, which goes up to 0.9 MPa.
