Airtac GAFR Adjustable Filter Regulator GAFR40010SJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010SJW 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 3/8" 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 GAFR40010SJW
The GAFR40010SJW is a filter and regulator combined into a single body, eliminating the need for separate units. It handles 3/8in ports and delivers a regulated output from 0.15 to 0.9 MPa (20-130 psi), with a 5 um filter element for finer particle removal.
This 880 g unit features a 100 cc condensate bowl and a circular gauge with MPa/psi scale. The balanced regulator mechanism helps maintain steady outlet pressure as supply varies, while the diversion structure spins air to separate liquid water and solid particles into the bowl.

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 GAFR40010SJW Is Used
Precision valve control
Feed a bank of precision pneumatic valves with 5 um filtered air at a stable 0.15-0.9 MPa setpoint, protecting sensitive spools from particle wear.
Machine tool air supply
Supply a CNC machine's clamping fixtures with clean, regulated air. The 100 cc bowl handles condensate from a typical shift, and the 7000 L/min envelope at 0.7 MPa inlet supports multiple actuators.
Test bench setup
Power a pneumatic test fixture requiring a precise, adjustable pressure. The balanced regulator holds the setpoint as shop air pressure fluctuates, and the gauge lets you verify output at a glance.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010SJW the Right Air-Prep Unit?
Choose this GAFR400 for 3/8in port applications needing finer 5 um filtration. The J code means no mounting bracket is included, so plan for panel mounting or use an existing bracket. The standard pressure type covers 0.15-0.9 MPa (20-130 psi), suitable for most industrial circuits. The semi-auto and manual drains are both fitted, giving you flexibility for maintenance. The PT thread and MPa/psi gauge scale match common regional standards. If you need oil downstream, order the matching GAFC400-10 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 your inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFC400-10 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR40010SJW FAQ
The GAFR40010SJW is a filter & regulator with a 3/8in port, 100 cc drain bowl, and 880 g weight. It operates from 0.15 to 0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum pressure and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. It uses a 5 um element and has both semi-auto and manual drains.
The J code in GAFR40010SJW means the mounting bracket is omitted. This suits installations where the unit is panel-mounted or secured by existing brackets. If you need the standard bracket, order the same model without the J code.
