Airtac GAFR Adjustable Filter Regulator GAFR40010L
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010L 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 GAFR40010L
The GAFR40010L is a filter and regulator combined in a single body, so one compact unit cleans the air and locks the outlet pressure. It suits a 3/8in line and delivers a lower 0.15-0.4 MPa (20-58 psi) regulated band, with a 40 um element trapping solid particles and spun-out water droplets.
This 880 g body carries a 100 cc condensate bowl, and the circular gauge with MPa/psi scale is fitted as standard. The balanced regulator holds the set pressure steady as supply varies, and the pressed-in self-locking knob resists drift from vibration.

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 GAFR40010L Is Used
Low-pressure assembly tools
Feed a 3/8in line to pneumatic screwdrivers or torque tools that must never see more than 0.4 MPa, protecting delicate fastening operations.
Lab air benches
Supply a clean, regulated air source to laboratory fixtures or test jigs where a stable low pressure is essential and the 40 um filter keeps particles out.
Light packaging machines
Run a single packaging station or a small indexing table with a steady 0.15-0.4 MPa feed, using the 100 cc bowl to collect condensate between maintenance rounds.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010L the Right Air-Prep Unit?
Choose the GAFR40010L when a 3/8in port and a lower pressure ceiling of 0.4 MPa match the machine's needs. The PC bowl is the standard build, the semi-auto plus manual drain is fitted, and the mounting bracket is included in the box. If the line later needs oil downstream, order the matching GAFC400-10 combination instead of this unit. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated 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 GAFR40010L FAQ
It is a filter & regulator with a 3/8in port, working pressure 0.15-0.4 MPa (20-58 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 40 um element, 100 cc drain bowl, and 880 g weight.
The L code sets the regulated band to 0.15-0.4 MPa instead of the standard 0.15-0.9 MPa. This is for applications that need a consistent low pressure and must not accidentally be set higher, such as delicate grippers or air bearings.
