Airtac GAFR Adjustable Filter Regulator GAFR30015SJNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015SJNWK 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 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR30015SJNWK
The GAFR30015SJNWK is a filter and regulator combined into a single body, replacing a separate GAF filter and GAR regulator with one unit that has fewer joints to seal and takes up less rail width. It handles a 1/2in port and delivers a standard pressure range of 0.15-0.9 MPa (20-130 psi) with a 5 um element.
Its diversion structure spins incoming air to separate liquid water and trap solid particles before the balanced, self-locking regulator holds the outlet steady as supply pressure varies. This model ships without a gauge and without a mounting bracket, and it includes a reverse-flow (reflux) valve as an ordering difference.

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 GAFR30015SJNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station where the 5 um element protects fine internal passages and the regulator holds a steady setpoint.
Single machine tool
Supply a lathe or milling machine's air chuck and coolant valves with filtered, regulated air from a compact 500 g unit that mounts directly on the machine frame.
Test bench air supply
Provide clean, stable air to a laboratory test fixture where the 1/2in port handles moderate flow and the semi-auto drain keeps the bowl from flooding during long runs.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015SJNWK the Right Air-Prep Unit?
Choose this 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 and 5 um element suit general industrial lines where finer filtration is needed, while the semi-auto plus manual drain gives you both automatic dumping and a manual override. The J code means no bracket is included, and the N code means no gauge is fitted - the 1/8in gauge connection is there if you add one later. This unit has the reverse-flow valve (K) and PT threads with an MPa/psi gauge scale. If your line needs oil downstream, the matching GAFC300-15 combination adds a lubricator. 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 GAFR30015SJNWK FAQ
The GAFR30015SJNWK is a filter and regulator with a 1/2in port, a working pressure range of 0.15-0.9 MPa (20-130 psi), a maximum pressure of 1.0 MPa (145 psi), and a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 60 cc drain bowl, and weighs 500 g. The element is 5 um, the bowl is PC, and it has a semi-auto plus manual drain.
The N after the port code means no gauge is supplied - the 1/8in gauge connection is there if you want to add one. The J code means the mounting bracket is omitted, which suits panel-mount installations or setups that already have a bracket. Both options reduce cost when you don't need the standard accessories.
