Airtac GAFR Adjustable Filter Regulator GAFR300C10SNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR300C10SNWK 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 GAFR300C10SNWK
The GAFR300C10SNWK is a filter & regulator with both functions in one body, so it replaces a separate GAF filter plus GAR regulator and cuts the number of sealed joints. It handles a 3/8in port with a 0.15-0.9 MPa (20-130 psi) standard range, filters to 5 um, and uses a metal bowl.
A diversion structure spins the incoming air to drop liquid water and solid particles into the 60 cc drain bowl, while the balanced regulator holds the outlet steady as supply pressure varies. The pressed-in self-locking knob resists drift from vibration, and the unit weighs 500 g.

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 GAFR300C10SNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves with 5 um filtered air at a stable 0.15-0.9 MPa, where finer filtration protects sensitive pilot stages.
Machine tool circuits
Supply a 3/8in line to a machine tool's clamping or indexing circuit, with the metal bowl standing up to shop-floor conditions.
Test bench air
Provide clean, regulated air to a test bench where the 60 cc bowl and manual drain allow quick visual checks between runs.
Is the Airtac GAFR Adjustable Filter Regulator GAFR300C10SNWK the Right Air-Prep Unit?
Choose the GAFR300 body for 3/8in or 1/4in and 1/2in ports, with a 3500 L/min flow envelope at 0.7 MPa inlet; step up to GAFR400 for a 7000 L/min envelope if you need more capacity. The metal bowl is a build choice, and the 5 um element traps finer particles than the standard 40 um for precision valves. This model has the semi-auto plus manual drain, the mounting bracket included, no gauge (the 1/8in gauge connection is ready for one), and a PT thread with MPa/psi scale. The reverse-flow (reflux) valve is fitted as an ordering difference, and if you need oil downstream, order the matching GAFC300-10 combination instead. Note that 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 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 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 GAFR300C10SNWK FAQ
It is a filter & regulator with a 3/8in port, 0.15-0.9 MPa (20-130 psi) working range, 1.0 MPa (145 psi) max pressure, 1.5 MPa (215 psi) proof pressure, and -5 to 70 C temperature range. The drain bowl holds 60 cc, the unit weighs 500 g, and the flow curve is plotted to 3500 L/min at 0.7 MPa inlet.
The K indicates a reverse-flow (reflux) valve is fitted to the unit. It is an ordering difference from the standard model, and its specific function is detailed in the catalogue page not included in our data.
