Axial Flow Fans date back to the horizontally configured windmills of Europe in the Middle Ages. The first electrically powered fans, introduced in the 1880s, were axial fans. Axial fans are named for the direction of the airflow they create. Blades rotating around an axis draw air in parallel to that axis and force air out in the same direction. Axial fans create airflow with a high flow rate, meaning they create a large volume of airflow. However, the airflows they create are of low pressure. They require a low power input for operation. http://www.dhlcentrifugalfan.com/axial-flow-fan/

Because of the high pressure they create, centrifugal fans are ideal for high pressure applications such as drying and air conditioning systems. As all of the moving parts of small centrifugal fans are enclosed and they also have particulate reduction properties that makes them ideal for use in air pollution and filtration systems. Remember to get the suitable fan accessories series for normal work of your fans. http://www.hongkefans.com/small-axial-fan/

Because of the low-pressure high-volume airflows they create, axial fans especially small axial fans are best suited for general purpose applications. For example, they excel at moving air from one place to another, cooling confined spaces such as computers, and cooling larger spaces such as work spaces. http://www.hongkefans.com/small-axial-fan/
