Airtac GAFR Adjustable Filter Regulator GAFR300C10LNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C10LNWK 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 GAFR300C10LNWK
The GAFR300C10LNWK is a filter and regulator combined into a single body, so the incoming air is cleaned and then set to a steady outlet pressure without needing separate units. This model uses a lower-pressure range of 0.15-0.4 MPa (20-58 psi) and comes with a 5 um element for finer filtration.
It has a metal bowl, a semi-auto plus manual drain, and a reverse-flow valve fitted. The unit weighs 500 g and has a 60 cc condensate bowl, with the gauge connection sized at 1/8in. There is no lubricator in this unit; it only filters and regulates.

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 GAFR300 is 1/8" 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 GAFC300-10 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 GAFR300C10LNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves on a small assembly station. The 5 um element protects fine internal passages, and the lower pressure range suits delicate actuation.
Lab air supply
Supply a laboratory test rig that needs clean, regulated air at modest pressures. The metal bowl handles the environment, and the semi-auto drain allows quick manual purging.
Single actuator feed
Power a single guided actuator on a light-duty machine. The 3/8in port and 500 g body are sized for a compact footprint, while the 60 cc bowl reduces frequent draining.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300C10LNWK the Right Air-Prep Unit?
Choose this GAFR300 body for 3/8in ports where the flow envelope is plotted to 3500 L/min at 0.7 MPa inlet. The metal bowl is a build choice; the common 1.0 MPa max and -5 to 70 C range apply to all bowl materials. This model has the semi-auto plus manual drain, a 5 um element, the mounting bracket included, and no gauge fitted. The L type tops out at 0.4 MPa, so if the machine may need more pressure, the standard S type is the right part. The reverse-flow valve is an ordering difference only. If oil is needed downstream, the matching GAFC300-10 combination adds a lubricator. With a 1.0 MPa max supply, you have about 0.6 MPa 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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 500 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 GAFC300-10 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR300C10LNWK FAQ
The pressure range is 0.15-0.4 MPa (20-58 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 500 g.
The K code indicates a reverse-flow (reflux) valve is fitted. It is an ordering difference from the standard model; the catalogue defers its function to a separate page, so no operational details are provided here.
