Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJWK 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 GAFR400C10ASJWK
The GAFR400C10ASJWK is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. This 3/8in model handles 0.15-0.9 MPa (20-130 psi) and uses a 5 um element to trap fine particles before regulation.
A circular gauge with MPa/psi scale is fitted, and the metal bowl holds 100 cc of condensate. The automatic drain clears water without manual intervention, while the reverse-flow valve is attached as an ordering option.

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 GAFR400C10ASJWK Is Used
Precision valve protection
Feed a bank of precision pneumatic valves with 5 um filtered air from this 3/8in unit, keeping fine particulates away from sensitive spools and orifices.
Medium assembly line
Mount this 880 g regulator on a machine frame to supply steady 0.15-0.9 MPa air to multiple actuators on a medium-speed assembly station.
Panel-mounted installation
Use the no-bracket (J) version for direct panel mounting where existing supports exist, saving rail space with the single-body filter-regulator design.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10ASJWK the Right Air-Prep Unit?
Choose the GAFR400 for 3/8in or 1/2in ports where the 7000 L/min flow envelope at 0.7 MPa inlet suits medium automation lines. The metal bowl (C) suits demanding environments, and the 5 um element (W) protects precision valves from fine particulates. This model ships without a bracket (J) for panel mounting, and the automatic drain (A) handles wet or unattended lines. The PT thread gives an MPa/psi gauge scale, and the reflux valve (K) is fitted. If downstream lubrication is needed, order the GAFC400-10 combination instead. At 880 g, this unit needs proper frame support, not tubing. Max supply 1.0 MPa 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 GAFR400C10ASJWK FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The metal drain bowl holds 100 cc and the unit weighs 880 g. It uses a 5 um element and has an automatic drain.
The K indicates a reverse-flow (reflux) valve is fitted. It is an ordering difference from standard models; the catalogue defers its function details to a separate page not included in our data.
