Airtac GAFR Adjustable Filter Regulator GAFR40010SJNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010SJNW 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 GAFR40010SJNW
The GAFR40010SJNW is a filter and regulator combined in a single body, so it cleans the air and sets a steady outlet pressure without needing separate units. This 3/8in version handles 0.15-0.9 MPa (20-130 psi) and uses a 5 um element to trap fine particles. It has no lubricator and only one bowl, the 100 cc condensate bowl.
Its diversion structure spins the airflow to drop liquid water and solid grain into the bowl, while the balanced regulator holds the set pressure as supply varies. Weighing 880 g, this unit needs a proper panel or frame mount rather than support from the tubing, and it ships without a gauge or bracket.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. No gauge is supplied with this model — the gauge connection on a GAFR400 is 1/4" if you add one. This unit filters and regulates only; it does not add lubrication.

The filter and the regulator are ONE body here — there is no separate GAF filter or GAR regulator part to assemble. Need lubrication downstream too? Add a lubricator by ordering the matching GAFC400-10 F.R.L. combination instead.

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 GAFR40010SJNW Is Used
Precision valve control
Feed a bank of precision pneumatic valves that need clean, regulated air at a stable pressure. The 5 um element protects fine internal passages, and the balanced regulator keeps the outlet steady as line pressure fluctuates.
Machine tool circuits
Mount on a machine tool's control panel to supply filtered air to cylinders and actuators. The 100 cc bowl handles condensate from moderate use, and the semi-auto drain lets operators purge it during routine checks.
Automated assembly jigs
Use on an assembly jig with multiple small actuators that need consistent pressure. The compact 880 g body fits tight spaces, while the 5 um element suits sensitive tooling that cannot tolerate particles.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010SJNW the Right Air-Prep Unit?
Choose GAFR400 for 3/8in or 1/2in ports; its 7000 L/min flow envelope at 0.7 MPa inlet inlet sits between the GAFR300's 3500 L/min and the GAFR500's 8000 L/min. The PC bowl suits general use, while the 5 um element here filters finer than the standard 40 um for precision valves. This model has a semi-auto plus manual drain, no mounting bracket (J), and no gauge, so the 1/4in gauge connection is ready if you add one later. The PT thread gives an MPa/psi gauge scale, and the standard type covers 0.15-0.9 MPa. For lines needing oil downstream, order the matching GAFC400-10 combination instead. 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range.
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 GAFR40010SJNW FAQ
It is a filter and regulator with a 3/8in port, working range 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), and temperature range -5 to 70 C. The drain bowl holds 100 cc, the unit weighs 880 g, and it uses a 5 um element. It has a semi-auto plus manual drain, no gauge, and no bracket.
The J code means the mounting bracket is omitted, for panel-mount or existing brackets. The N code means no gauge is supplied, so the set pressure cannot be read without adding one; the 1/4in gauge connection is ready for a gauge with an MPa/psi scale, matching the PT thread.
