The blades of a forward inclined fan are curved forward in relation to the impeller rotation, hence the name forward inclined fan.

Forward inclined fans are mostly used for relatively low speeds, high air volumes and low pressures.

Usually, the selection pressure of the front inclined fan does not exceed 1000Pa, and the static pressure efficiency generally does not exceed 55%

The high outlet air velocity of the forward inclined fan makes it possible to obtain large air volumes at low speeds, in general

The lower has the advantage of small size and low noise compared to other types of fans, but is less efficient.

Forward inclined fans at a fixed speed, if the pressure decreases and the air volume increases, the fan shaft power will increase dramatically, the

This phenomenon is known as overload phenomenon and can easily lead to motor burnout.
