Airtac GAFR Adjustable Filter Regulator GAFR40010SNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010SNWK 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 GAFR40010SNWK
The GAFR40010SNWK is a filter & regulator with both functions in a single body, so it replaces a separate GAF filter and GAR regulator with one compact unit that has fewer joints to seal. It handles a 3/8in port, delivers 0.15-0.9 MPa (20-130 psi), and uses a 5 um element for finer particle removal.
This model comes with a PC bowl, a semi-auto plus manual drain, and no gauge fitted, though the 1/4in gauge connection is ready if you add one later. The reverse-flow (reflux) valve is attached as an ordering difference, and the 880 g mass means it needs a proper panel or frame mount rather than support from the tubing.

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 GAFR40010SNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a machining fixture where the 5 um element protects fine internal passages from abrasive wear.
Machine tool air supply
Supply a single CNC machine's clamping circuit with filtered, regulated air, using the 100 cc bowl to handle condensate from a humid compressor line.
Test bench setup
Power a pneumatic test rig that cycles actuators at varied pressures, relying on the balanced regulator to hold the setpoint as shop supply fluctuates.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010SNWK the Right Air-Prep Unit?
Choose GAFR400 for a 3/8in or 1/2in port with a 100 cc drain bowl, stepping up from GAFR300's 60 cc bowl if you want fewer drain interventions. The PC bowl suits standard shop air, while the semi-auto plus manual drain lets you empty condensate automatically or on demand. The 5 um element traps finer particles than the standard 40 um, but expect more frequent element service. The included bracket simplifies mounting, and the PT thread pairs with an MPa/psi gauge scale if you fit one. If your line needs oil downstream, order the matching GAFC400-10 combination instead. A 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 GAFR40010SNWK FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), max pressure is 1.0 MPa (145 psi), and proof pressure is 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 N after the port code means no gauge is supplied, but the 1/4in gauge connection is ready for a field-installed unit. The K code indicates a reverse-flow (reflux) valve is fitted, which is an ordering difference from the standard version.
