Airtac GAFR Adjustable Filter Regulator GAFR30008ASNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008ASNWK 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 GAFR30008ASNWK
The GAFR30008ASNWK is a filter and regulator combined into a single body, handling both filtration and pressure control in one compact unit. It uses a diversion structure to spin the air, separating liquid water and solid particles into the 60 cc condensate bowl, while the balanced regulator mechanism maintains a steady outlet pressure as supply varies.
This model has a 1/4in port and a standard pressure range of 0.15-0.9 MPa (20-130 psi). It comes with a 5 um filter element for finer particle removal, an automatic drain for unattended operation, and a PC bowl. The mounting bracket is included, but no gauge is fitted; the 1/8in gauge connection is available if you need to add one.

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 GAFR30008ASNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves that need clean, regulated air. The 5 um element protects sensitive internals from fine particulate, while the balanced regulator holds a stable setpoint.
Machine tool air supply
Supply a single CNC machine's air system with filtered, regulated pressure. The automatic drain removes condensate continuously, reducing maintenance visits on a busy production line.
Test bench setup
Power a laboratory test fixture that requires a consistent 0.4 MPa supply. The self-locking knob resists drift from vibration, keeping the set pressure stable during long test cycles.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008ASNWK the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in or 3/8in ports, with a 3500 L/min flow envelope at 0.7 MPa inlet. The PC bowl suits general-purpose use, while the 5 um element traps finer particles for sensitive equipment. The automatic drain handles condensate without manual intervention, ideal for wet lines. The included bracket simplifies mounting, and the PT threads match standard gauge scales. If you need lubrication downstream, order the matching GAFC300-08 combination instead. For this model, the 1.0 MPa max supply leaves about 0.1 MPa above the 0.9 MPa top of the range, so plan your inlet pressure accordingly.
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 GAFR30008ASNWK FAQ
This filter & regulator has a 1/4in port, a standard pressure range of 0.15-0.9 MPa (20-130 psi), and a maximum pressure of 1.0 MPa (145 psi). Proof pressure is 1.5 MPa (215 psi), and the operating temperature range is -5 to 70 C. The drain bowl holds 60 cc, and the unit weighs 500 g.
The K indicates a reverse-flow (reflux) valve is fitted to this unit. It is an ordering difference from standard models. The function of this valve is detailed in the full catalogue, which is not included in our data.
