Airtac GAFR Adjustable Filter Regulator GAFR400C10ASWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10ASWK 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 GAFR400C10ASWK
The GAFR400C10ASWK is a filter and regulator combined into a single body, eliminating the need for separate GAF filter and GAR regulator units. This 3/8in model operates from 0.15 to 0.9 MPa (20-130 psi) and comes with a 5 um filtering element, making it suitable for applications requiring finer particle removal.
Its metal bowl and automatic drain are built for continuous operation, while the integrated circular gauge with MPa/psi scale provides clear pressure readout. The balanced, self-locking regulator mechanism maintains stable outlet pressure despite supply variations, and the diversion structure inside spins the air to separate liquid water and solid contaminants into the 100 cc condensate bowl.

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 GAFR400C10ASWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a machining center where the 5 um element protects tight clearances and the balanced regulator holds set pressure steady.
Machine tool header
Supply a compact machine tool header with filtered, regulated air at 3/8in, using the automatic drain to shed condensate during long production runs.
Test bench air supply
Provide clean, stable air to a laboratory test bench where the metal bowl resists rough handling and the gauge allows quick pressure verification.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10ASWK 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, placing it between the lighter GAFR300 (60 cc, 500 g) and the heavier GAFR500 (108 cc, 950 g). The metal bowl (C) suits demanding environments, while the automatic drain (A) handles unattended operation. This standard type (S) covers 0.15-0.9 MPa, the 5 um element (W) traps finer particles than the standard 40 um, and the included bracket simplifies mounting. The PT thread provides an MPa/psi gauge scale, and the reverse-flow valve (K) is fitted as an ordering option. For lines needing oil downstream, 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 GAFR400C10ASWK FAQ
This filter & regulator has a 3/8in port, 0.15-0.9 MPa (20-130 psi) working range, 1.0 MPa (145 psi) max pressure, 1.5 MPa (215 psi) proof pressure, and operates from -5 to 70 C. It has a 100 cc drain bowl, weighs 880 g, includes a 5 um element, and comes with an automatic drain and metal bowl.
The K indicates a reverse-flow (reflux) valve is fitted. This is an ordering difference from models without K; the catalogue defers the valve's function details to a separate page not included in our data.
