Airtac GAFR Adjustable Filter Regulator GAFR30008LNWK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR30008LNWK 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 - 0.4 MPa (20 - 58 psi). It has no lubricator, so it adds no oil to the airflow.

About the Airtac GAFR Adjustable Filter Regulator GAFR30008LNWK
The GAFR30008LNWK is a filter and pressure regulator combined into one compact body, saving rail space and reducing potential leak points compared to separate units. This model uses a 1/4in port, a 5 um element, and a lower-pressure range of 0.15-0.4 MPa (20-58 psi), with a 60 cc condensate bowl.
Its diversion structure spins incoming air to separate liquid water and solid particles, while the balanced regulator holds the set outlet pressure steady as supply varies. A reverse-flow valve is fitted, and the unit includes a mounting bracket, though no gauge is supplied-the 1/8in gauge connection is ready for one if needed.

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 GAFR30008LNWK Is Used
Instrument Air Feed
Feed a precision pneumatic controller or a small valve island that needs clean, regulated air at a modest pressure, with the 5 um element protecting internal orifices.
Bench Test Rig
Supply a lab or test bench where a stable 0.15-0.4 MPa output is required for experiments or calibration, and the compact 500 g body mounts easily on a frame.
Single Actuator Line
Protect and regulate air for one small cylinder or a rotary actuator on a light assembly fixture, where the 60 cc bowl gives adequate condensate capacity between checks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR30008LNWK the Right Air-Prep Unit?
Choose the GAFR300 body for 1/4in or 3/8in ports and a flow envelope plotted to 3500 L/min at 0.7 MPa inlet, stepping up from the GAFR200's 2000 L/min curve. The PC bowl suits general shop air; the 5 um element traps finer particles for sensitive equipment, while the semi-auto plus manual drain handles routine condensate removal. The L-type regulator tops out at 0.4 MPa, so confirm your system never needs more than that. The bracket is included, the gauge is omitted (1/8in connection), and the reflux valve is fitted as an ordering difference. If oil is needed downstream, order the matching GAFC300-08 combination instead. Note that 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 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 GAFR30008LNWK FAQ
It is a filter & regulator with a 1/4in port, working pressure 0.15-0.4 MPa (20-58 psi), max pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi), temperature range -5 to 70 C, 5 um filter element, 60 cc drain bowl, and weight 500 g.
The 'L' code sets the regulator to 0.15-0.4 MPa for applications that never need higher output. The 'N' after the port means no gauge is included; the 1/8in gauge connection is capped and ready for a field-installed gauge if you need to read the set pressure.
