Airtac GAFR Adjustable Filter Regulator GAFR40015SJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015SJW 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 GAFR40015SJW
The GAFR40015SJW is a filter and pressure regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/2in port with a standard pressure range of 0.15-0.9 MPa (20-130 psi) and uses a 5 um filter element for finer particle removal.
This 880 g unit features a clear PC bowl with both semi-auto and manual drains, allowing flexible condensate removal. The integrated circular gauge with MPa/psi scale provides direct pressure reading. This model ships without a mounting bracket, so plan for panel mounting or use an existing bracket.

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 GAFR40015SJW Is Used
Precision machining center
Feed a 5 um filtered, regulated air supply to a CNC machine's tool changer and clamping system, where consistent pressure and fine filtration protect sensitive valves and actuators.
Assembly line automation
Supply a multi-station assembly fixture with a stable 0.15-0.9 MPa output, using the 100 cc bowl to handle condensate from a busy production line before it reaches downstream components.
Packaging equipment
Regulate air for a case packer's pneumatic cylinders and sensors, where the 5 um element prevents fine dust from interfering with precision pilot valves and the gauge allows quick pressure verification.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015SJW the Right Air-Prep Unit?
Choose this GAFR400 body for medium-flow applications needing a 1/2in port and a 100 cc condensate bowl. The 5 um element traps finer particles than the standard 40 um, suitable for precision valves or instrument air, though it will require more frequent servicing. The PC bowl is the standard choice, while the semi-auto and manual drains give you both automatic dumping and manual override. The J code means no bracket is included, so verify your mounting setup. This standard type covers 0.15-0.9 MPa, and the PT thread comes with an MPa/psi gauge scale. If you need lubrication downstream, order the matching GAFC400-15 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa regulated top.
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 GAFR40015SJW FAQ
The GAFR40015SJW is a filter & regulator with a 1/2in port, working pressure range of 0.15-0.9 MPa (20-130 psi), max pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). It operates in -5 to 70 C temperatures, has a 100 cc drain bowl, and weighs 880 g. It comes with a 5 um element and a circular gauge.
The J in the model code means the mounting bracket is not included. This unit is intended for panel mounting or for use with an existing bracket from your setup. The 880 g weight requires a secure mount, not support from the tubing alone. You can also order the standard version without J to get the bracket included.
