Airtac GAFR Adjustable Filter Regulator GAFR400C10AS
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10AS 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 40 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 GAFR400C10AS
The GAFR400C10AS is a filter and regulator combined into a single body, so incoming air is cleaned and then set to a steady outlet pressure without needing separate components. This 3/8in unit with a metal bowl handles 0.15-0.9 MPa (20-130 psi) and uses a 40 um element, with the circular gauge showing MPa/psi.
The automatic drain releases condensate without manual attention, and the 100 cc bowl holds the separated water and solids. At 880 g, this body is a mid-size unit that suits machine headers or multi-tool stations, and the included bracket allows secure panel mounting.

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 GAFR400C10AS Is Used
Machine tool header
Feed a 3/8in header supplying multiple pneumatic cylinders on a machining center. The automatic drain keeps the line dry during long shifts, and the 100 cc bowl reduces maintenance stops.
Assembly station air prep
Prepare air for a semi-automatic assembly station with torque tools and pick-and-place units. The 40 um element protects sensitive valves, while the regulator holds a stable setpoint for consistent operation.
Test rig supply
Supply a test bench that checks actuator cycles or leak integrity. The metal bowl resists knocks in a busy lab, and the included bracket lets you mount the unit securely to the rig frame.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10AS the Right Air-Prep Unit?
Choose the body and port to match your flow demand: the GAFR400's 3/8in port and 7000 L/min plotted curve at 0.7 MPa inlet step up from the GAFR300's 3500 L/min envelope. The metal bowl suits demanding shop environments, while the automatic drain removes the need for manual checks on wet lines. The standard pressure type covers 0.15-0.9 MPa, the bracket is included, and the 40 um element handles general workshop air. If you need finer filtration, the W option swaps to 5 um; for oil downstream, order the GAFC400-10 combination instead. The PT thread gives an MPa/psi gauge scale, and the K option adds a reverse-flow valve. 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 GAFR400C10AS 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, 40 um element, and automatic drain.
The automatic drain expels condensate from the 100 cc bowl without manual intervention, which is useful for wet lines or unattended operation. The standard blank option instead ships with both semi-auto and manual drains, but this A version handles drainage automatically.
