Airtac GAFR Adjustable Filter Regulator GAFR30008ASJW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008ASJW 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 GAFR30008ASJW
The GAFR30008ASJW is a filter and regulator combined into a single body, eliminating the need for separate GAF and GAR units. 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. This model has a 1/4in port, a 0.15-0.9 MPa (20-130 psi) working range, and a 5 um filter element for finer particle removal.
With a 60 cc condensate bowl and a 500 g weight, this unit is sized for light to medium duty circuits. The automatic drain (A) clears condensate without manual intervention, and the included circular gauge shows the set pressure on an MPa/psi scale. No bracket is supplied (J), so plan for panel mounting or an existing support structure.

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 GAFR30008ASJW Is Used
Precision valve control
Feed a 5 um-filtered air supply to a precision pneumatic valve or a small instrument loop where fine particles could cause sticking or wear.
Bench test rigs
Mount this regulator on a test bench to provide a stable, adjustable pressure for calibrating gauges or validating small actuators.
Single-station automation
Use it to protect and control a single pick-and-place station or a small clamping fixture, where the 1/4in port matches common valve islands.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008ASJW the Right Air-Prep Unit?
Choose the body and port first: the GAFR300 with a 1/4in port handles flows plotted to 3500 L/min at 0.7 MPa inlet, a step up from the GAFR200's 2000 L/min envelope. The bowl is polycarbonate (PC), a standard build choice; the 5 um element (W) traps finer particles than the standard 40 um, but will need more frequent service. The automatic drain (A) suits unattended lines, while the standard pressure type (S) covers 0.15-0.9 MPa. This unit has no bracket (J) and no reverse-flow valve; the PT thread matches the MPa/psi gauge scale. If oil is needed downstream, order the matching GAFC300-08 combination instead. With a 1.0 MPa max supply, you have about 0.1 MPa of headroom above the 0.9 MPa regulated top.
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 GAFR30008ASJW FAQ
Working pressure is 0.15-0.9 MPa (20-130 psi), with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 500 g. It has a 5 um filter element and an automatic drain.
The W code specifies a 5 um element, which traps much finer solid particles than the standard 40 um grade. This is beneficial for precision valves or instrument air, but the finer element will load up faster and require more frequent cleaning or replacement.
