Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJN
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJN 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 40 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 GAFR200N08ALJN
The GAFR200N08ALJN is a genuine AirTAC filter and regulator combined into a single body, so it cleans incoming air and stabilizes outlet pressure without needing separate units. This version has a 1/4in port, a nylon bowl, and a lower-pressure range of 0.15-0.4 MPa (20-58 psi), with a 40 um element for standard filtration.
Because the filter and regulator share one housing, this unit replaces two separate components, reducing potential leak points and saving space on the rail. The automatic drain clears condensate without manual attention, and the 25 cc bowl holds the water and solids removed by the diversion structure, which spins the air to separate them from the flow.

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.

Where the Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJN Is Used
Precision Fixture Clamping
Feed a single pneumatic clamp on a small assembly fixture with a steady 0.15-0.4 MPa supply, while the filter removes water and particles from the air before it reaches the actuator.
Lab Air Supply
Provide filtered, regulated air at lower pressures to a laboratory bench setup or a single test station, where the automatic drain keeps the bowl from overflowing during long experiments.
Compact Machine Build
Mount this lightweight 290 g unit on a small machine frame or panel to condition air for a single cylinder, using the included 1/8in gauge connection to monitor output if you add a gauge.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200N08ALJN the Right Air-Prep Unit?
Choose this GAFR200 body when your line needs a compact unit with a 1/4in port, as it is the smallest in the GAFR series at 290 g. The nylon bowl offers an alternative to the standard PC, while the automatic drain (A) suits unattended operation or wet lines, and the missing bracket (J) means you plan to panel-mount it or use an existing bracket. The lower-pressure type (L) tops out at 0.4 MPa, so confirm your system never needs more than that, and note that no gauge is fitted, though the 1/8in gauge connection allows one to be added later. If you need to lubricate downstream equipment, order the matching GAFC200-08 combination instead, as this unit does not add oil. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of the regulated range, which is a comfortable margin for stable operation.
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 GAFR200N08ALJN FAQ
The GAFR200N08ALJN is a filter and regulator with a 1/4in port, a nylon bowl, and an automatic drain. It operates in a lower pressure range of 0.15-0.4 MPa (20-58 psi), with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C, and it must not freeze. The drain bowl holds 25 cc, and the unit weighs 290 g.
The 'N' after the port code means no gauge is supplied, so you cannot read the set pressure directly, but the 1/8in gauge connection allows you to add one later. The 'J' code means the mounting bracket is omitted, which is useful if you are panel-mounting the unit or using an existing bracket, but you will need to provide your own mounting solution.
