We design, engineer, and manufacture high quality, high performance DC fans and blowers. Our innovative brushless cross flow designs provide high efficiency and outstanding longevity, even in the most demanding thermal management applications.
DC Brushless Cross Flow Fans for All Applications
Our industrial DC cross flow fans are commonly used to cool computer equipment and other sensitive electronics, and can be found in countless other applications across all commercial and industrial markets.
We know that no one fan design is right for every need, and with that in mind, we offer 25mm, 30mm, 36mm, 38mm, 40mm, 50mm, 60mm, 70mm, 80mm, 92mm, 120mm, and 172mm DC cross flow fan options. All models feature state-of-the-art technology and deliver exceptional performance and reliability, with low noise.
At the most basic level, the key difference between DC fans and AC fans is the type of electricity they use: direct current or alternating current. While direct current (DC) can only flow in one direction, alternating current (AC) can change direction quickly to maintain a more constant flow. Typically, AC fans operate on a higher voltage than DC fans; thus, they are better suited to high pressure or high airflow applications.
Pros & Cons of DC Brushless Fans
Pro – lower power consumption: Up to 70% more efficient than AC fans
Pro – less electromagnetic interference (EMI): ideal for sensitive electronic devices
Pro – quieter operation: far less noise than AC fans
Con – variable flow: DC fans cannot provide the constant, even flow that AC fans can
Con – require a transformer: DC technology cannot be connected directly to a power source, necessitating the use of a transformer to convert AC electricity to DC
Pro – constant, even airflow: AC technology allows for consistent operation and airflow
Con – higher power consumption: though still quite efficient, AC fans do use more power than their DC counterparts
Con – louder operation: increased noise may be a nuisance in many applications
Con – more EMI: AC electricity generates more electromagnetic interference, which can cause problems for electronic devices
