Airtac GAFR Adjustable Filter Regulator GAFR40015ASJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015ASJWK 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 GAFR40015ASJWK
The GAFR40015ASJWK is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. It handles 1/2in ports, operates from 0.15 to 0.9 MPa (20-130 psi), and comes with a 5 um element for finer filtration.
Its diversion structure spins incoming air to separate liquid water and solid particles into the 100 cc drain bowl, while the balanced regulator maintains a steady outlet pressure. The pressed-in self-locking knob resists drift from vibration, and the circular gauge with clip and magnifier saves panel space.

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 GAFR40015ASJWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a machining center. The 5 um element protects sensitive spools from fine wear particles, while the automatic drain keeps the 100 cc bowl from filling on wet shop air.
Machine tool header
Supply a clean, regulated 0.15-0.9 MPa (20-130 psi) air header to a multi-station assembly machine. The 1/2in port and 880 g body handle the flow, and the self-locking knob holds the setpoint despite machine vibration.
Instrument air skid
Use on a test bench or calibration skid where 5 um filtration protects downstream instrumentation. The circular gauge with magnifier allows operators to read the set pressure clearly, and the automatic drain reduces maintenance checks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015ASJWK the Right Air-Prep Unit?
Choose this GAFR400 body for medium-flow lines needing 1/2in ports and a 100 cc condensate bowl. The 5 um element traps finer particles than the standard 40 um, making it suitable for precision valves or instrument air, though it will require more frequent element service. The automatic drain handles unattended or wet lines, and the PT thread specifies an MPa/psi gauge scale. With the J code, no mounting bracket is included, so plan for a panel mount or existing bracket. The K code indicates a reverse-flow (reflux) valve is fitted. If lubrication is needed downstream, order the matching GAFC400-15 combination instead. Max supply 1.0 MPa 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 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 880 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 GAFC400-15 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR40015ASJWK FAQ
The GAFR40015ASJWK is a filter & regulator with a 1/2in port, working pressure range of 0.15-0.9 MPa (20-130 psi), maximum pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). It operates in temperatures from -5 to 70 C, has a 100 cc drain bowl, and weighs 880 g. It comes with a 5 um element and an automatic drain.
The K code indicates a reverse-flow (reflux) valve is fitted to the GAFR40015ASJWK. This is an ordering difference from models without the K code. The catalogue defers the function of this valve to a separate page, so consult the full AirTAC documentation for operational details.
