Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJNW
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJNW 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 GAFR200N08ALJNW
The GAFR200N08ALJNW is a filter and pressure regulator combined into a single body, eliminating the need for separate units. It handles a 1/4in port and delivers a lower pressure range of 0.15-0.4 MPa (20-58 psi) with a 5 um filter element.
This compact 290 g unit features a nylon bowl and an automatic drain, making it suitable for applications where regular manual draining is impractical. The diversion structure inside spins the airflow to separate liquid water and solid particles, protecting downstream components.

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.

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 GAFR200N08ALJNW Is Used
Precision Fixturing
Feed a single pneumatic clamp or small positioning jig that needs clean, regulated air at a consistent low pressure without risking over-pressurization.
Laboratory Air Supply
Provide filtered air at a stable low pressure to sensitive lab instruments or test benches where fine particle removal is critical and space is limited.
Bench Assembly Station
Power a small hand tool or air blow gun at a workbench, with the automatic drain reducing maintenance in a busy assembly environment.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJNW the Right Air-Prep Unit?
Choose this GAFR200 when your line needs a compact 1/4in filter-regulator with a low pressure ceiling. The nylon bowl offers an alternative to PC or metal, while the automatic drain handles condensate without manual intervention. This model omits the mounting bracket for panel-mount installations and comes without a gauge, though the 1/8in gauge connection is ready if you add one later. The 5 um element traps finer particles than the standard 40 um for sensitive equipment. If your application requires lubrication downstream, order the matching GAFC200-08 combination instead. With a maximum supply of 1.0 MPa, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated 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 GAFR200N08ALJNW FAQ
The GAFR200N08ALJNW operates from 0.15 to 0.4 MPa (20-58 psi) with a maximum pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). It is rated for -5 to 70 C, has a 25 cc drain bowl, and weighs 290 g.
The J code means the mounting bracket is omitted for installations using existing brackets or panel mounts. The N after the port code indicates no gauge is supplied, but the 1/8in gauge connection is present if you need to add one for pressure monitoring.
