Airtac GAFR Adjustable Filter Regulator GAFR40010AL
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010AL 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 GAFR40010AL
The GAFR40010AL is a filter and regulator combined into a single body, handling both air preparation steps without the need for separate units. This model uses a 3/8in port, operates in the lower pressure band of 0.15-0.4 MPa (20-58 psi), and comes with a 40 um element.
Its 100 cc condensate bowl and 880 g mass place it in the mid-range size class, suitable for machine headers where space is at a premium. The automatic drain clears collected water without manual intervention, and the integrated circular gauge shows the set pressure on an MPa/psi scale.

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 GAFR40010AL Is Used
Precision Fixturing
Feed a clamping fixture on a CNC machine with a stable 0.3 MPa supply, using the lower pressure range to avoid over-clamping delicate workpieces.
Machine Header Supply
Provide filtered, regulated air to a single station on an assembly line, where the 3/8in port matches typical manifold inlets and the automatic drain reduces maintenance.
Lab Air Bench
Supply a laboratory pneumatic bench where a maximum of 0.4 MPa protects experimental setups, with the 40 um element trapping particles from the main line.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010AL the Right Air-Prep Unit?
Choose the GAFR40010AL when your circuit needs a regulated output capped at 0.4 MPa, such as for delicate air tools or sensitive actuators. The 3/8in port suits branch lines feeding a single machine station, while the 100 cc bowl holds more condensate than the 60 cc unit on a GAFR300, meaning less frequent draining. The automatic drain (A) handles wet supply lines without operator attention, and the included bracket simplifies panel mounting. The standard 40 um element covers general shop air; select a W variant for 5 um filtration if you have precision valves downstream. This model keeps the PT thread with an MPa/psi gauge scale, and the L-type regulation range is about 44% of the standard 0.9 MPa ceiling, so confirm your maximum required pressure stays below 0.4 MPa before ordering.
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 GAFR40010AL FAQ
The GAFR40010AL is a filter & regulator with a 3/8in port, working pressure range of 0.15-0.4 MPa (20-58 psi), and a maximum supply pressure of 1.0 MPa (145 psi). It has a proof pressure of 1.5 MPa (215 psi), operates from -5 to 70 C, and includes a 40 um element. The condensate bowl holds 100 cc and the unit weighs 880 g.
The 'L' in the code designates the lower-pressure type, which tops out at 0.4 MPa instead of the standard 0.9 MPa. This is chosen when downstream equipment requires a limited pressure ceiling for safety or precision. If your application might need more than 0.4 MPa, you would need a standard 'S' type model instead.
