Airtac GAFR Adjustable Filter Regulator GAFR30015SNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015SNK 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 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR30015SNK
The GAFR30015SNK is a filter and pressure regulator combined in a single body, so one unit cleans the air and sets a steady outlet pressure. It has no lubricator and only one bowl, the 60 cc condensate bowl. This model uses a 1/2in port, a 40 um element, and a standard pressure range of 0.15-0.9 MPa (20-130 psi).
The pressed-in self-locking knob resists set-pressure drift from vibration, helping the balanced regulator hold the outlet steady as supply pressure varies. A diversion structure spins the incoming air to separate liquid water and trap solid particles before regulation. The unit weighs 500 g and comes with the mounting bracket included.

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.

The filter and the regulator are ONE body here — there is no separate GAF filter or GAR regulator part to assemble. Need lubrication downstream too? Add a lubricator by ordering the matching GAFC300-15 F.R.L. combination instead.

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 GAFR30015SNK Is Used
Single-station jig
Feed a single pneumatic jig or fixture with clean, regulated air at a steady 0.15-0.9 MPa. The 1/2in port suits short runs to one actuator.
Bench test setup
Use on a test bench where a compact 500 g unit with a 60 cc bowl supplies a consistent pressure to a small valve manifold. The self-locking knob holds the setpoint.
Light assembly line
Protect a light assembly station's tools from water and particles. The diversion filter spins out condensate, and the semi-auto drain clears the 60 cc bowl on schedule.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015SNK the Right Air-Prep Unit?
Choose the GAFR300 body for a 1/2in port with a 60 cc drain bowl and a flow curve plotted to 3500 L/min at 0.7 MPa inlet. The PC bowl suits general-purpose lines; the semi-auto drain plus manual drain means you can empty it on schedule or automatically when pressure drops. The 40 um element handles standard shop air, while the included bracket simplifies panel mounting. This model has no gauge fitted, so the 1/8in gauge connection is ready if you add one later. The PT thread carries an MPa/psi scale. The reverse-flow (reflux) valve is fitted as an ordering difference. If the line needs oil downstream, order the matching GAFC300-15 combination instead. 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the 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 GAFR30015SNK FAQ
The GAFR30015SNK is a filter & regulator with a 1/2in port. Pressure range is 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C. It has a 40 um element, a 60 cc drain bowl, and weighs 500 g.
The N in the code means no gauge is supplied. The gauge connection is 1/8in, so you can fit a circular gauge later if you need to read the set pressure directly. Without one, you cannot see the outlet pressure on the unit.
