Airtac GAFR Adjustable Filter Regulator GAFR30015ASJNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30015ASJNWK 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 GAFR30015ASJNWK
The GAFR30015ASJNWK is a genuine AirTAC filter & regulator that combines both functions in a single body, saving rail space and reducing potential leak points versus separate units. This model has a 1/2in port, a standard pressure range of 0.15-0.9 MPa (20-130 psi), and a fine 5 um element for trapping smaller particles.
The unit comes with an automatic drain and a 60 cc condensate bowl, but no gauge or mounting bracket. A reverse-flow valve is fitted, and the PT thread option uses an MPa/psi gauge scale. Weighing 500 g, this size class is suited for medium-flow applications where a compact footprint matters.

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 GAFR30015ASJNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves with the 5 um element filtering out fine particulates that could clog or wear sensitive internal components.
Medium conveyor line
Supply a medium-duty conveyor system where the 1/2in port and 60 cc bowl balance flow capacity with manageable maintenance intervals.
Machine tool circuits
Use in a machine tool circuit where the automatic drain handles condensate without operator intervention, keeping the air supply stable for consistent actuation.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30015ASJNWK the Right Air-Prep Unit?
Choose this GAFR300 body for a 1/2in port and a 60 cc drain bowl, stepping up from the GAFR200's 25 cc bowl for longer intervals between drains. The automatic drain suits unattended or wet lines, while the 5 um element provides finer filtration for sensitive equipment. Since the bracket is omitted (J), plan for a panel mount or existing support. No gauge is supplied (N), but the 1/8in gauge connection allows adding one later. The PT thread pairs with an MPa/psi scale. If oil is needed downstream, order the matching GAFC300-15 combination instead. Note that the 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure accordingly.
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 GAFR30015ASJNWK FAQ
This filter & regulator has a 1/2in port, a standard 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 and must not freeze. The drain bowl holds 60 cc and the unit weighs 500 g.
The N code after the port means no gauge is supplied, leaving the 1/8in gauge connection available if you add one later. The J code omits the mounting bracket, so you will need a panel mount or an existing bracket for installation.
