Airtac GAFR Adjustable Filter Regulator GAFR400C10AL
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR400C10AL 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR400C10AL
The GAFR400C10AL 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 model uses a 3/8in port, a metal bowl, and an automatic drain, with a lower-pressure range of 0.15-0.4 MPa (20-58 psi) and a 40 um element.
Its 100 cc condensate bowl and 880 g weight place it in the GAFR400 size class, which is built for medium-flow lines. The balanced regulator mechanism holds the set pressure steady as supply varies, and the pressed-in self-locking knob resists drift from vibration, making it a stable choice for production equipment.

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 GAFR400C10AL Is Used
Precision machining center
Feed a consistent 0.15-0.4 MPa supply to a CNC tool changer or work-holding fixture, where the lower pressure range protects sensitive actuators.
Assembly line pick-and-place
Supply a medium-duty pick-and-place unit on an assembly line, with the automatic drain handling condensate without manual checks.
Test rig air supply
Provide filtered, regulated air to a test rig that requires a stable low pressure, with the metal bowl standing up to shop-floor conditions.
Is the Airtac GAFR Adjustable Filter Regulator GAFR400C10AL the Right Air-Prep Unit?
Choose the GAFR400 body when you need a 3/8in port and a flow envelope plotted to 7000 L/min at 0.7 MPa inlet, stepping up from the GAFR300's 3500 L/min envelope. The metal bowl is a build choice for demanding environments, while the automatic drain suits unattended or wet lines. This L-type unit tops out at 0.4 MPa, so confirm your machine never needs more than that; the bracket is included, the gauge is fitted with an MPa/psi scale, and the element is 40 um. If oil is needed downstream, order the matching GAFC400-10 combination instead. Note that 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 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 GAFR400C10AL FAQ
The GAFR400C10AL is a filter & regulator with a 3/8in port, a 0.15-0.4 MPa (20-58 psi) pressure range, a 1.0 MPa (145 psi) max pressure, and a 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C, has a 100 cc drain bowl, and weighs 880 g.
The L code designates a lower-pressure type, topping out at 0.4 MPa instead of the standard 0.9 MPa. This suits applications that need a gentle, precise supply, but if your machine may ever require more pressure, the standard S type would be the correct choice.
