How quiet are these axial fans?

The main tag line of these axial fans is the super silent highlight. With the low starting voltage, the fan would run at a slower speed than various other fans, perfect in environments where noise pollution could be an issue, such as hospitals or household appliances. This however does not hinder the cooling air which emits from the fan itself.

What is an axial fan?

An axial fan is a type of fan commonly used within everyday applications, such as air conditioners, computers and laptops. It causes both air and gas (depending on the application) to flow directly through it in an axial direction at different speeds. Allowing the air flow to be axial at both entry and exit. The most common versions tend to have fewer impeller blades than conventional ducting fans or centrifugal fans which have similar operations. Ball bearing or sleeve bearing axial fans are the most commonly used. However ceramic bearings are also used.

What kind of bearing is supplied with this axial fan?

This fan uses Sleeve bearings. Sleeve bearings are a more cost effective solution than the more common ball bearing version. As the bearings in the fan will need to stay lubricated, sleeve bearing axial fans are oiled with a thinner and more concentrated version, leading to a smoother operation.
