Airtac GAFR Adjustable Filter Regulator GAFR40010ASJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010ASJW 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 GAFR40010ASJW
The GAFR40010ASJW is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. This 3/8in port model handles a standard pressure range of 0.15-0.9 MPa (20-130 psi) and comes with a 5 um element for finer filtration.
Its 100 cc condensate bowl and 880 g weight place it in the mid-size class, suitable for machine headers. The automatic drain clears collected water without manual intervention, while the circular gauge with MPa/psi scale shows the set outlet pressure.

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 GAFR40010ASJW Is Used
Machine tool circuits
Feed a 3/8in line to a machining center's clamping fixtures, where the 5 um element protects precision valves from fine wear particles.
Assembly station headers
Supply a multi-operator assembly bench with filtered, regulated air, using the automatic drain to handle condensate from a humid plant air system.
Test rigs
Power pneumatic test fixtures that need a steady 0.15-0.9 MPa supply, with the 100 cc bowl reducing how often operators must check the drain.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010ASJW the Right Air-Prep Unit?
Choose the GAFR400 body when you need 3/8in ports and a 100 cc drain bowl, stepping up from the GAFR300's 60 cc bowl for longer intervals between drains. This model has a PC bowl, a 5 um element for finer particle removal, and an automatic drain for wet or unattended lines. The J code means no mounting bracket is included, so plan for panel mounting or an existing bracket. The standard S type covers 0.15-0.9 MPa, and the fitted gauge reads in MPa/psi with PT threads. If you need lubrication 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 GAFR40010ASJW FAQ
It operates at 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g.
The J code omits the standard bracket for installations where the unit is panel-mounted or secured to an existing frame. This saves space and hardware when you have a dedicated mounting solution already in place.
