A JYF-50S inline fan that sits in a run of 50mm (2 inch) pipe or hose and pulls air through it at up to 36 m³/h, about 21 CFM. That is the right size for venting a 3D printer enclosure, an electronics cabinet, a battery box or a composting toilet, and too small for a grow tent or bathroom. It runs from 12V DC at 6W, so a 12V plug pack or a 12V battery powers it. No power supply comes with it: the short lead ends in a female DC barrel socket, ready for a 12V supply with a barrel plug.

Wiring & getting started
- Pick a 12V supply
Use a 12V DC plug pack rated 1 A or more with a barrel plug that fits the fan's socket, or a 12V battery. To wire it to a battery or screw terminals, our barrel jack screw terminal adapter comes in both common barrel sizes, 5.5x2.1mm and 5.5x2.5mm. A solar panel on its own runs at around 18 to 22V, so connect the fan to the battery or the controller's 12V load output, not straight to the panel.
- Point the arrow the way the air should go
The arrow on the label shows the airflow, and the fan only blows that way. To pull air out of a box, the arrow points away from the box. Join it to your 50mm hose or pipe with a hose clamp, a rubber coupling or tape, so air cannot leak around the joint.
- Power up and set the speed
At 12V it runs at full speed with a noticeable high-pitched whine. If you need it quieter, run it from a lower voltage, for example from an adjustable step-down converter: it slows down and gets much quieter, while still moving air through the pipe.
