Airtac GAFR Adjustable Filter Regulator GAFR40010LNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010LNW 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR40010LNW
The GAFR40010LNW 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 lower-pressure model operates from 0.15 to 0.4 MPa (20-58 psi) and uses a 5 um element to trap fine particles.
With a 3/8in port and an 880 g mass, this unit suits compact machine builds where space is tight. The 100 cc condensate bowl collects separated water and solids, and the included mounting bracket provides secure panel attachment.

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 GAFR40010LNW Is Used
Precision valve control
Feed a precision pneumatic valve or small actuator with regulated air at up to 0.4 MPa, where the 5 um element protects fine internal passages from particle wear.
Compact machine builds
Mount this 880 g unit on a small assembly machine or test rig where space is limited, using the included bracket to secure it to a panel or frame.
Instrument air supply
Supply a sensitive instrument or pressure sensor with filtered, regulated air, relying on the 5 um element to remove fine contaminants before they reach the device.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010LNW the Right Air-Prep Unit?
Choose the GAFR400 body when you need 3/8in or 1/2in ports with a 100 cc drain bowl; it sits between the GAFR300 (60 cc bowl) and GAFR500 (108 cc bowl) in capacity. The L type is limited to 0.4 MPa, so confirm your system never needs more than that regulated output. This model has the 5 um element for finer filtration, a PC bowl, and both semi-auto and manual drains fitted. The bracket is included, and no gauge is supplied, but the 1/4in gauge connection allows adding one later. If oil is needed downstream, order the GAFC400-10 combination instead. The 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 GAFR40010LNW FAQ
The GAFR40010LNW is a filter & regulator with a 3/8in port, 0.15-0.4 MPa (20-58 psi) pressure range, 5 um element, 100 cc drain bowl, and 880 g weight. Maximum pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C.
The L type is a lower-pressure version of the regulator, designed for applications that only need up to 0.4 MPa output. It provides finer adjustment within that lower band. If your system might require more than 0.4 MPa, you would need the standard S type instead.
