Sunon DC Fans & Blowers

Range

SUNON’s extensive DC offering covers a wide range of sizes, each with different voltage, bearing and speed variations to suit every application.

For markets with very particular requirements, SUNON has developed ranges of DC fans that target these specific needs. The Super Silence range (HA series) delivers exceptional efficiency and low sound pressure (dbA), and utilizes SUNON’s patented MagLev bearing technology. The Power Fan range (PF/VF/VG series) is targeted at applications where high flow/velocity and reliability are a must.

MagLev

SUNON’s patented MagLev bearing system has become the gold standard across many industries. With minimal contact and friction, lower bearing temperatures contribute to its long life and high reliability. Unlike traditional ball and sleeve bearing options, sound pressure (dbA) does not increase over time and makes it the ideal choice for noise-sensitive applications.

Radial Blowers

Where air flow is needed under high static pressure conditions, radial blowers are a sensible option. With the air exit point at a 90° to the inlet, blowers can also provide a handy alternative where space is at a premium.

Additional Wires for Feedback & Control

Feedback on fan operation is a useful function for applications where the fan is critical. Locked rotor detection (R type) uses a square wave signal to signify that the fan is/is not operating. Tacho feedback (F type) measures RPM and can be utilised either to alert of early signs of fan failure (so the device can be serviced and replacement fitted prior to failure), or to fix fan performance. As there is a direct relationship between RPM (speed) and CFM (airflow), many choose to deploy an open loop system to adjust voltage to secure the correct speed. This method of control delivers consistent performance, and removes any impact of batch variation.

Pulse Width Modulation

PWM is recognised as the most efficient method of speed control. Selecting the right speed(s) for your application will optimise power consumption and extend fan life. On-board PWM removes potential risks such as power-cycling the IC and batch variation.

Ingress Protection

For applications where high levels of dust or moisture are likely, we encourage additional protection. IP21 conformal coating is applied to the fan PCB and is recommended for devices likely to encounter high humidity or steam. For outdoor applications or devices likely to come into contact with high levels of dust, IP55 is delivered through a double-dip conformal coating process and a covering with protective resin. Parylene coating is recommended for applications where the fan will be subjected to corrosives, such as salt water or cleaning fluids.

For applications where the fan will be subjected to severely harsh conditions or even submerged in fluid, SUNON also offer an extensive range of IP68 and GR487.

Custom Solutions

Standard fans are often useful when parts are needed quickly and forward planning isn’t possible. However, in most cases they’ll need some form of adjustment prior to your final assembly. Lead adjustments and the addition of connectors means additional processing. Our preference is always to supply fans/blowers that are ready for your assembly line. With wires cut to length and connectors fitted, reduced handling mitigates the risk of damage.

Packaging and labelling are other common customisation requests, delivering efficiencies with transport, goods inwards inspection and on assembly lines.

Managed Logistics

Economies of scale delivered through larger order quantities help you manage unit costs, but can come with logistics complications.

Not with Gelec!

We will store them for you, shipping them to your assembly location on an agreed schedule. We will work with you to forward-plan, navigating annual holidays and lead time changes to prevent interruptions to your supply.
