Airtac GAFR Adjustable Filter Regulator GAFR400C10SNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10SNW 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 GAFR400C10SNW
The GAFR400C10SNW is a filter & regulator that combines air filtration and pressure regulation in one compact body. This metal-bowl version handles a 3/8in port with a working range of 0.15-0.9 MPa (20-130 psi) and uses a 5 um element for finer particle removal.
Its 100 cc condensate bowl collects water and solids separated by the diversion structure, while the balanced regulator holds the outlet steady as supply varies. The pressed-in self-locking knob resists set-pressure drift from vibration, making this 880 g unit a stable choice for machine headers.

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 GAFR400C10SNW Is Used
Machine tool circuits
Feed a 3/8in line to a CNC machine's pneumatic clamping system where the 5 um element protects precision valves from fine particulates.
Assembly station headers
Supply a multi-operator assembly station with clean, regulated air at up to 0.9 MPa, using the 100 cc bowl to reduce drain frequency.
Test bench air supply
Provide stable pressure for pneumatic test fixtures where the balanced regulator holds setpoint despite supply fluctuations.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10SNW the Right Air-Prep Unit?
Choose the GAFR400C10SNW when you need a 3/8in port with a 5 um element and a metal bowl for demanding environments. The semi-auto drain plus manual drain gives you both automatic condensate release and manual override. The mounting bracket is included, but no gauge is fitted - the 1/4in gauge connection allows adding one later. This standard type covers 0.15-0.9 MPa (20-130 psi) with PT threads. If oil is needed 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.
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 GAFR400C10SNW 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 -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 880 g with a 3/8in port.
The N code means no gauge is supplied. The GAFR400 has a 1/4in gauge connection, so you can add a compatible AirTAC gauge later. Without one, the set pressure cannot be read directly on the unit.
