Airtac GAFR Adjustable Filter Regulator GAFR40010ASJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010ASJN 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 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 GAFR40010ASJN
The GAFR40010ASJN is a filter and pressure regulator combined into a single body, replacing a separate GAF filter plus GAR regulator with one compact unit. This 3/8in model handles 0.15-0.9 MPa (20-130 psi) and uses a 40 um element to trap solids while the diversion structure spins out liquid water into the 100 cc drain bowl.
A balanced regulator mechanism holds the outlet steady as supply pressure varies, while the pressed-in self-locking knob resists drift from vibration. The automatic drain clears condensate without manual intervention, and this version ships without a gauge or mounting bracket for panel-mount installations.

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 GAFR40010ASJN Is Used
Machine tool air supply
Feed a 3/8in line to a CNC machine's pneumatic clamping system, where the automatic drain keeps the 100 cc bowl clear during long production runs.
Assembly station header
Supply filtered, regulated air to multiple manual assembly tools on a workbench, with the 880 g body mounted to a frame rather than supported by tubing.
Test bench instrumentation
Provide a stable 0.15-0.9 MPa supply to pressure test fixtures, relying on the balanced regulator to hold setpoint as shop air pressure fluctuates.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010ASJN the Right Air-Prep Unit?
Choose the GAFR400 body when you need a 3/8in port with a 100 cc drain bowl and 880 g mass, stepping up from the GAFR300's 60 cc bowl when condensate volume is high. The automatic drain suits unattended lines, while the standard pressure type covers 0.15-0.9 MPa (20-130 psi). The J code omits the bracket for existing mounts, and the N code leaves the 1/4in gauge connection open for a field-installed gauge. The blank bowl code means a PC bowl, and the 40 um element is the standard grade. PT threads with MPa/psi gauge scale are fitted. If downstream lubrication is needed, order the matching GAFC400-10 combination instead. The 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 GAFR40010ASJN FAQ
Working pressure range is 0.15-0.9 MPa (20-130 psi), with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g. It uses a 40 um element and has a 1/4in gauge connection.
The N code means no gauge is supplied, leaving the 1/4in connection for a field-installed gauge if you need to read outlet pressure. The J code omits the mounting bracket, which suits panel-mount installations or setups where you already have a bracket in place.
