Airtac GAFR Adjustable Filter Regulator GAFR400C10SNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10SNWK 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 GAFR400C10SNWK
The GAFR400C10SNWK is a filter and regulator combined into one body, saving rail space compared to separate units. It handles a 3/8in port with a 100 cc metal condensate bowl, weighing 880 g, and uses a 5 um element for finer particle removal.
This standard type regulates from 0.15 to 0.9 MPa (20-130 psi). The metal bowl suits demanding environments, while the semi-auto and manual drains give operator control. A reverse-flow valve is fitted as an ordering difference, and the unit has no gauge, so the 1/4in gauge connection remains available for later installation.

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.

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 GAFR400C10SNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves that need clean, regulated air at 5 um filtration to protect internal orifices from fine wear particles.
Machine tool circuits
Supply a 3/8in line to a CNC machine's clamping circuit, where stable pressure and water separation keep cycle times consistent throughout the shift.
Test bench air supply
Provide filtered air to a laboratory test bench where operators read the set pressure from an external gauge, relying on the 100 cc bowl to handle condensate between checks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10SNWK the Right Air-Prep Unit?
Choose the GAFR400 for 3/8in or 1/2in ports where a 100 cc drain bowl and 880 g mass fit the machine layout. The metal bowl is a build choice, not a performance upgrade, so confirm compatibility with your surroundings. This model includes the mounting bracket, uses a 5 um element for finer filtration, and ships with both semi-auto and manual drains for flexible operation. The PT thread matches the MPa/psi gauge scale, and the reverse-flow valve is fitted per the K code. If the line needs oil downstream, order the matching GAFC400-10 combination instead. Note that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan inlet pressure near the maximum for full output.
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 GAFR400C10SNWK FAQ
Working pressure 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 has a 3/8in port, 5 um element, and no gauge.
The K code indicates the reverse-flow (reflux) valve is fitted as an ordering difference. The catalogue defers its function to a separate page, so treat it as a specified option for this unit rather than a standard feature.
