Airtac GAFR Adjustable Filter Regulator GAFR200C08ALJNK
The AirTAC Airtac GAFR Adjustable Filter Regulator GAFR200C08ALJNK 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 GAFR200C08ALJNK
The GAFR200C08ALJNK is a filter and regulator combined into a single body, saving rail space and reducing potential leak points compared to separate units. This 1/4in version operates in the lower pressure band of 0.15-0.4 MPa (20-58 psi) and uses a 40 um element to trap solids and separate liquid water via its diversion structure.
Its metal bowl and automatic drain make it suited for applications where condensate handling needs minimal attention. The pressed-in self-locking knob resists vibration-induced drift, helping maintain the set outlet pressure. Weighing 290 g, it is a compact unit for small machines or single actuators.

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 GAFR200C08ALJNK Is Used
Precision jig clamping
Feed a single pneumatic clamp or small fixture where a stable 0.15-0.4 MPa output is required and space is tight.
Bench-mounted tools
Supply a small air tool or bench press with filtered air at a controlled lower pressure, protecting sensitive components.
Lab test rigs
Use in a laboratory setup where a compact, filtered lower-pressure air source is needed for experiments or calibration.
Is the Airtac GAFR Adjustable Filter Regulator GAFR200C08ALJNK the Right Air-Prep Unit?
Choose this GAFR200 when your port requirement is 1/4in and your supply pressure stays below 0.4 MPa. The metal bowl (C) offers a different build option compared to PC or nylon, though all share the same 1.0 MPa max and -5 to 70 C rating. The automatic drain (A) removes condensate without manual intervention, and the absence of a bracket (J) means you plan to panel-mount it. No gauge is fitted (N), so the 1/8in gauge connection is available if you add one later. The reverse-flow valve (K) is an ordering difference; its function is detailed in the catalogue. If your line needs oil downstream, order the matching GAFC200-08 combination instead. With a 1.0 MPa max supply, you have about 0.6 MPa of headroom above the 0.4 MPa top of this unit's 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.
