Airtac GAFR Adjustable Filter Regulator GAFR300N10SNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300N10SNWK 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 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR300N10SNWK
The GAFR300N10SNWK is a filter and regulator combined into a single body, with no lubricator section. It cleans incoming air through a diversion structure that spins out liquid water and solid particles, then delivers a steady outlet pressure via a balanced, self-locking regulator mechanism. This model uses a 3/8in port, a nylon bowl, a 5 um element, and a semi-auto plus manual drain, with a working range of 0.15-0.9 MPa (20-130 psi).
Weighing 500 g with a 60 cc condensate bowl, this unit is sized for light industrial lines where space is tight. The pressed-in knob resists vibration-induced drift, keeping the set pressure stable. Since the filter and regulator share one housing, there are fewer potential leak points than with separate components, and the included mounting bracket simplifies panel installation.

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.

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 GAFR300N10SNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves that require clean, particle-free air at a stable pressure. The 5 um element protects sensitive internals from wear, while the balanced regulator holds the setpoint steady.
Compact machine build
Mount this unit on a small assembly machine or test rig where panel space is limited. The single-body design saves rail width compared to separate filter and regulator units, and the included bracket simplifies installation.
Light production line
Use it to condition air for a single actuator or a small pneumatic cylinder on a light assembly line. The 60 cc bowl provides adequate condensate capacity for intermittent operation, and the manual drain allows quick servicing.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300N10SNWK the Right Air-Prep Unit?
Choose this GAFR300 when your line needs 3/8in ports and a compact footprint. The nylon bowl is a build choice, not a performance upgrade, so confirm compatibility with your environment. The 5 um element traps finer particles than the standard 40 um, making it suitable for precision valves, though it will require more frequent servicing. The semi-auto drain releases condensate when pressure drops, with a manual override for immediate draining. A gauge is not fitted, but the 1/8in connection allows one to be added later; the PT thread uses an MPa/psi scale. The reverse-flow valve is an ordering difference only. If you need lubrication downstream, order the matching GAFC300-10 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 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 GAFR300N10SNWK FAQ
The working pressure range is 0.15-0.9 MPa (20-130 psi), with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). The operating temperature range is -5 to 70 C and the unit must not freeze. It has a 3/8in port, a 60 cc drain bowl, and weighs 500 g. The filter element is 5 um, and the drain is semi-auto plus manual.
The K code indicates a reverse-flow (reflux) valve is fitted, which is an ordering difference from the standard version. The N code after the port means no gauge is supplied; the 1/8in gauge connection is available if you need to add one. The 5 um element is chosen for finer filtration, and the nylon bowl is a material option.
