Airtac GAFR Adjustable Filter Regulator GAFR20008ALJNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR20008ALJNW 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 GAFR20008ALJNW
The GAFR20008ALJNW is a compact filter and regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. It handles a 1/4in port with a lower-pressure range of 0.15-0.4 MPa (20-58 psi) and uses a fine 5 um element for trapping small particles.
This unit spins incoming air to separate liquid water and solid debris into its 25 cc condensate bowl, while the balanced regulator maintains a steady outlet pressure. The pressed-in self-locking knob resists drift from vibration, keeping settings stable in demanding environments.

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 GAFR200 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 GAFC200-08 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 GAFR20008ALJNW Is Used
Precision Valve Control
Feed a single precision pneumatic valve or small actuator where the 5 um element protects fine internal passages and the lower pressure range prevents over-pressurization.
Bench Assembly Station
Supply clean, regulated air to a bench-mounted assembly tool or fixture, with the automatic drain ensuring the 25 cc bowl never overflows during long shifts.
Lab Air Supply
Provide filtered air to a laboratory instrument or test setup that requires stable low pressure, with the compact body fitting into tight equipment racks.
Is the Airtac GAFR Adjustable Filter Regulator GAFR20008ALJNW the Right Air-Prep Unit?
Choose this GAFR200 body for small jigs or single actuators where a 1/4in port and light weight (290 g) are sufficient. The automatic drain (A) handles condensate without manual intervention, ideal for wet or unattended lines. The 5 um element filters finer particles than the standard 40 um, suited for precision valves but requiring more frequent service.
This model comes without a mounting bracket (J) and without a gauge (N); the 1/8in gauge connection allows adding one later if needed. The lower-pressure type (L) tops out at 0.4 MPa, so verify your supply never needs more. With a 1.0 MPa max supply, you have 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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 290 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 GAFC200-08 combination; do not expect an oil mist from this unit.
Airtac GAFR Adjustable Filter Regulator GAFR20008ALJNW FAQ
Pressure range is 0.15-0.4 MPa (20-58 psi), max pressure is 1.0 MPa (145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -5 to 70 C. The drain bowl holds 25 cc and the unit weighs 290 g. It has a 1/4in port and a 5 um filter element.
The J code omits the mounting bracket for panel-mount or existing bracket setups, and the N code means no gauge is supplied. The 1/8in gauge connection is available if you add one later. This reduces cost when these features are not needed.
