Airtac GAFR Adjustable Filter Regulator GAFR30008ASJNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008ASJNWK 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 GAFR30008ASJNWK
The GAFR30008ASJNWK is a filter & regulator in a single body, combining a diversion-type filter with a balanced pressure regulator. It handles 1/4" ports and delivers a standard 0.15-0.9 MPa (20-130 psi) outlet range, with a 5 um element for finer particle removal.
This 500 g unit replaces separate filter and regulator components, reducing potential leak points and saving rail space. It includes a reverse-flow valve and an automatic drain, but no gauge and no mounting bracket, so plan for panel mounting and a separate pressure readout.

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 GAFR30008ASJNWK Is Used
Precision valve control
Feed a bank of precision pneumatic valves with the 5 um element filtering out fine particulates that could clog small orifices. The automatic drain keeps the 60 cc bowl from filling during long production runs.
Unattended machine station
Mount this unit on a machine frame where the automatic drain handles condensate without an operator. The 1/4" port suits single-actuator stations, and the self-locking regulator holds set pressure despite machine vibration.
Panel-mounted air prep
Install this compact 500 g unit on an existing panel using your own bracket, saving rail space. The 1/8" gauge connection lets you add a remote pressure readout where operators can see it clearly.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008ASJNWK the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4" or 3/8" port lines; it offers a 60 cc drain bowl and a flow curve plotted to 3500 L/min at 0.7 MPa inlet. The PC bowl suits standard shop air, while the automatic drain handles wet or unattended lines without manual intervention. The 5 um element traps finer particles than the standard 40 um, ideal for sensitive valves, though it will need more frequent service. The omitted bracket suits existing panels, and the missing gauge means you must add one via the 1/8" connection to read set pressure. The reverse-flow valve is fitted as an ordering difference. If oil is needed downstream, order the matching GAFC300-08 combination instead. 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 (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 GAFR30008ASJNWK FAQ
This filter & regulator has a 1/4" port, a 0.15-0.9 MPa (20-130 psi) pressure range, a 1.0 MPa (145 psi) maximum, and a 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C, has a 60 cc drain bowl, and weighs 500 g. It includes a 5 um element, an automatic drain, and a reverse-flow valve, with no gauge and no bracket.
The J code omits the mounting bracket for installations that use existing panels or custom mounts, saving cost and space. The N code (after the port) omits the gauge; you can add one through the 1/8" gauge connection if you need to read outlet pressure directly.
