Description
This centrifugal fan (also known as a blower or squirrel cage fan) pushes a large amount of air in a highly directed fashion. This means it’s great for cooling small or tricky to reach objects – such as the upper part of your 3D printer’s hotend. The fan motor is brushless, ensuring a long operational lifespan.
These fans run on 12V and should draw less than 120mA under regular conditions. The attached cable is ~20cm in length and is terminated in a 2-pin JST connector. They are great for keeping the upper section of your hotend cool – this helps prevent thermal creep, which can often be a problem during longer prints. Long story short, one of these fans will make it much easier to achieve long, reliable prints. These fans also work great for ducted designs – they push air at a much higher pressure when compared to a regular bladed fan, meaning you can ‘pump’ air around with them. Because these fans run on 12V, they're easy to wire in with your other printer electronics.
