Sunon HA Series Axial Fan, 12 V dc, DC Operation, 5.5m³/h, 440mW, 36mA Max, 30 x 30 x 10mm

Brought to you by Sunon, The Super Silence HA Fan Series of axial fans are designed to the highest environmental standards to ensure the best acoustic quality. The low starting voltage enables the fan to run at a low speed without losing its highly efficient cooling purpose. The Super Silence DC fan series is suitable for a wide range of uses, including household, commercial and medical applications. All models are highly reliable and excellent quality.

• Micro-motor technology
• Low starting voltage
• Low noise level
• High performance bearings
• Smooth and unrestricted airflow

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.

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.

This fan uses Vapo bearings. Vapo bearings are a Sunon exclusive design. They completely eliminate any wobbling or non axial movement whilst the fan is in full operation, which is excellent when performing at a high pressure speed. Sunon have also made these bearings completely dust-proof, this will provide a superior life expectancy of the axial fan.
