Airtac GAFR Adjustable Filter Regulator GAFR30008SNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008SNWK 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 1/4" 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 GAFR30008SNWK
The GAFR30008SNWK is a filter and pressure regulator combined in a single body, saving rail space and reducing potential leak points compared to separate units. It handles 1/4in ports, operates from 0.15 to 0.9 MPa (20-130 psi), and comes with a 5 um element for finer filtration.
Its diversion structure spins incoming air to separate liquid water and solid particles into the 60 cc condensate bowl. The balanced regulator mechanism helps maintain a steady outlet pressure as supply varies, while the pressed-in self-locking knob resists drift from vibration. This model includes a reverse-flow valve and a semi-auto plus manual drain, with no gauge fitted.

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 GAFC300-08 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 GAFR30008SNWK Is Used
Precision valve control
Feed a 5 um filtered, regulated air supply to precision pneumatic valves on a small assembly station, where consistent pressure and fine particle removal protect sensitive components.
Single actuator stations
Mount this 1/4in unit on a jig or test rig to power one or two actuators, using the included bracket for a stable panel installation and the manual drain for periodic service.
Light machine headers
Use it as a point-of-use filter regulator on a light machine header, where the 60 cc bowl and 5 um element handle typical condensate and particulate loads without frequent attention.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008SNWK the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in or 3/8in ports, with a flow curve plotted to 3500 L/min at 0.7 MPa inlet. The 500 g weight and 60 cc drain bowl sit between the smaller GAFR200 and larger GAFR400, making it a mid-range choice for single machines. The PC bowl and 5 um element suit general industrial air; the included bracket simplifies mounting, and the semi-auto plus manual drain allows flexible condensate removal. The PT thread and MPa/psi gauge scale match common regional fittings, and the reverse-flow valve is fitted per the K code. For lines needing oil downstream, order the matching GAFC300-08 combination instead. With a 1.0 MPa max supply, the 0.9 MPa regulated top leaves only about 0.1 MPa of headroom, so plan for a supply pressure near the maximum to achieve the highest setpoint.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFC300-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR30008SNWK FAQ
The GAFR30008SNWK is a filter & regulator with a 1/4in port, working pressure range of 0.15-0.9 MPa (20-130 psi), max pressure of 1.0 MPa (145 psi), and proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C, has a 60 cc drain bowl, and weighs 500 g. The unit includes a 5 um element, semi-auto plus manual drain, and a reverse-flow valve.
The N after the port code means no gauge is supplied; the 1/8in gauge connection is available if you add one later. The K code indicates a reverse-flow (reflux) valve is fitted, which is an ordering difference from standard models. This unit has a PC bowl and includes the mounting bracket.
