Airtac GAFR Adjustable Filter Regulator GAFR40010ASK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010ASK 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 GAFR40010ASK
The GAFR40010ASK is a filter and regulator combined into one body, so incoming air is spun to separate liquid water and solid particles before the balanced regulator sets a steady outlet pressure. This model uses a 3/8in port, works from 0.15 to 0.9 MPa (20-130 psi), and comes with a 40 um element and a circular gauge showing MPa/psi.
Its 100 cc condensate bowl and 880 g mass place it in the mid-size class, where the included mounting bracket is essential for proper panel or frame installation. The automatic drain clears collected water without manual intervention, making it suitable for unattended operation on wet supply lines.

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 GAFR40010ASK Is Used
Machine tool air preparation
Feed a 3/8in line to a CNC machine's pneumatic clamps or tool changer with filtered, regulated air. The automatic drain keeps the 100 cc bowl from overflowing during long shifts, and the gauge confirms set pressure at a glance.
Assembly station supply
Power pneumatic screwdrivers or presses at a workbench where consistent pressure is critical. The balanced regulator holds outlet pressure steady as line supply varies, while the 40 um element protects downstream valves from debris.
Test rig instrumentation
Supply clean, regulated air to a test fixture with sensors and small cylinders. The 880 g unit mounts securely on a panel, and the included bracket prevents movement that could stress tubing connections.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010ASK the Right Air-Prep Unit?
Choose the GAFR40010ASK when you need a 3/8in port with a 100 cc drain bowl and the convenience of an automatic drain. The PC bowl suits general-purpose industrial air, while the standard pressure type covers 0.15-0.9 MPa (20-130 psi) for most pneumatic circuits. The included bracket simplifies mounting, and the fitted gauge lets you read set pressure directly. The 40 um element handles typical workshop air, and the PT thread with MPa/psi scale matches common regional fittings. If your line needs oil downstream, order the matching GAFC400-10 combination instead, since this unit does not lubricate. Remember that 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 GAFR40010ASK FAQ
The GAFR40010ASK is a filter & regulator with a 3/8in port, 100 cc drain bowl, and 880 g weight. Pressure range is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C. It has a 40 um element, automatic drain, PC bowl, and fitted gauge with MPa/psi scale.
The K indicates a reverse-flow (reflux) valve is fitted to the GAFR40010ASK. This is an ordering difference from models without K; the valve is drawn as a separate pneumatic symbol in the catalogue. For details on its function, please confirm from the AirTAC datasheet.
