Airtac GAFR Adjustable Filter Regulator GAFR40015ASJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015ASJW 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 GAFR40015ASJW
The GAFR40015ASJW is a genuine AirTAC filter & regulator, combining both functions in a single body. It cleans incoming air through a diversion structure that spins out liquid water and solid particles, then delivers a steady outlet pressure via a balanced, self-locking regulator. 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 filter element.
This 880 g unit is built for medium-flow lines, with a 100 cc condensate bowl and an automatic drain for low-maintenance operation. The circular gauge with MPa/psi scale is fitted, and the pressed-in self-locking knob resists drift from vibration. This is a single-body solution that replaces a separate filter and regulator, reducing potential leak points and saving rail 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 GAFR40015ASJW Is Used
Precision Valve Control
Feed a bank of precision pneumatic valves with clean, regulated air. The 5 um element protects fine internal passages from particle wear, while the balanced regulator holds set pressure steady as line supply fluctuates.
Machine Tool Air Supply
Supply a medium-sized machine tool with a stable 0.15-0.9 MPa air source. The 100 cc bowl and automatic drain keep the unit running with minimal attention, and the 1/2in port matches common header piping.
Automated Assembly Station
Use it on an automated assembly station with multiple actuators. The single-body design saves space on the rail, and the 880 g weight requires a proper frame mount rather than tubing support.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015ASJW the Right Air-Prep Unit?
Choose this GAFR400 body for 3/8in or 1/2in port lines that need a 100 cc condensate bowl and a flow envelope plotted to 7000 L/min at 0.7 MPa inlet. 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 service. The automatic drain (A) handles condensate without manual intervention, ideal for wet or unattended lines. This model ships without the mounting bracket (J), so plan for a panel mount or existing bracket. The PT thread (blank) means the gauge reads in MPa/psi. With a maximum supply of 1.0 MPa, you have about 0.1 MPa above the 0.9 MPa top of the 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 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 GAFR40015ASJW FAQ
This filter & regulator has 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 in temperatures from -5 to 70 C and must not freeze. The condensate bowl holds 100 cc, and the unit weighs 880 g. It uses a 5 um filter element and has an automatic drain.
The J code in GAFR40015ASJW means the mounting bracket is omitted. This is for installations where the unit will be panel-mounted or attached to an existing bracket. If you need the standard bracket, order the same model without the J suffix.
