Airtac GAFR Adjustable Filter Regulator GAFR40015SJ
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40015SJ 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 40 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 GAFR40015SJ
The GAFR40015SJ is a filter and regulator combined into a single body, handling both filtration and pressure control without a separate lubricator. It uses a 1/2in port, a 40 um element, and a standard pressure range of 0.15-0.9 MPa (20-130 psi), with a 100 cc condensate bowl that defines its service rhythm.
Its diversion structure spins incoming air to separate liquid water and solid particles into the bowl, while the balanced, self-locking regulator holds the outlet steady as supply pressure varies. At 880 g, this unit is a substantial component that needs a proper panel or frame mount rather than support from the tubing alone.

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 GAFR40015SJ Is Used
Machine tool air supply
Feed a single machining center or a small assembly station with clean, regulated air at a steady 0.15-0.9 MPa, using the 1/2in port to handle moderate flow demands.
Pneumatic valve manifold
Supply a bank of directional control valves on a production line, where the 100 cc bowl and 40 um element keep condensate and particles from reaching sensitive valve pilots.
Test bench setup
Provide a stable, adjustable air pressure to a laboratory fixture or calibration rig, relying on the balanced regulator to hold the setpoint as shop supply fluctuates.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40015SJ the Right Air-Prep Unit?
Choose the GAFR400 body for a 1/2in port with a 100 cc drain bowl and a flow envelope plotted to 7000 L/min at 0.7 MPa inlet, stepping up from the GAFR300's 3500 L/min for higher-demand lines. The PC bowl is the standard build, the semi-auto and manual drains are both fitted, and the 40 um element handles general shop air; the J code means no mounting bracket is included, so plan for a panel mount or existing bracket. The circular gauge is fitted with an MPa/psi scale on PT threads, and the standard S type covers 0.15-0.9 MPa (20-130 psi); if oil is needed downstream, order the matching GAFC400-15 combination instead. Note that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan a supply near 1.0 MPa for a 0.9 MPa setpoint.
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 GAFR40015SJ FAQ
The GAFR40015SJ is a filter and regulator with a 1/2in port, a 40 um element, and a standard pressure range of 0.15-0.9 MPa (20-130 psi). Maximum pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. It has a 100 cc drain bowl and weighs 880 g.
The J code means the mounting bracket is not included with the GAFR40015SJ. You will need to use a panel mount or an existing bracket to secure the 880 g unit, rather than relying on the included bracket that comes with the blank code.
