Airtac GAFR Adjustable Filter Regulator GAFR40010LNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR40010LNK 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 GAFR40010LNK
The GAFR40010LNK is a filter and regulator combined into a single body, so it cleans incoming air and sets a steady outlet pressure without needing separate units. This model uses a 3/8in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), and a 40 um element.
Its 100 cc condensate bowl collects water and solids separated by the diversion structure, while the pressed-in self-locking knob resists drift from vibration. The unit weighs 880 g and includes a mounting bracket, but no gauge is supplied; the 1/4in gauge connection allows one to be added later.

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 GAFR40010LNK Is Used
Precision valve control
Feed a 3/8in line to a precision pneumatic valve that needs a stable, lower pressure setting. The balanced regulator holds the outlet steady as supply varies, and the 40 um element protects the valve from particles.
Bench test rigs
Use on a test bench where a compact filter-regulator supplies a single actuator or fixture. The 100 cc bowl handles condensate from a moderate air draw, and the included bracket mounts it securely to a panel.
Light assembly stations
Install at a light assembly station to provide filtered, regulated air to a hand tool or small cylinder. The lower pressure range suits delicate operations, and the self-locking knob keeps the setting stable.
Is the Airtac GAFR Adjustable Filter Regulator GAFR40010LNK the Right Air-Prep Unit?
Choose the GAFR400 body for a 3/8in port and a 100 cc drain bowl, which holds about 2.5 times the condensate of a GAFR300's 60 cc bowl, meaning less frequent draining. The lower-pressure type tops out at 0.4 MPa, so if your machine might need more than that, select a standard S type instead. This model has a PC bowl, a semi-auto plus manual drain, and the mounting bracket is included. The 40 um element is standard; a 5 um element (W) is available for finer filtration. The K code indicates a reverse-flow valve is fitted, and the PT thread uses an MPa/psi gauge scale. If you need oil downstream, order the matching GAFC400-10 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this unit's 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 GAFR40010LNK FAQ
The GAFR40010LNK is a filter and regulator with a 3/8in port, a lower-pressure range of 0.15-0.4 MPa (20-58 psi), and a maximum pressure of 1.0 MPa (145 psi). Proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. It has a 100 cc condensate bowl and weighs 880 g.
The K code indicates a reverse-flow (reflux) valve is fitted to this GAFR40010LNK. It is an ordering difference from models without the K code. The catalogue defers the function of this valve to a separate page, so its operation is not detailed here.
