Axial fans and centrifugal fans are two different types of products within the fan category, both primarily serving the function of ventilating and air-exchanging within an environment. The differences between axial fans and centrifugal fans are as follows: 1. Air exhaust direction: Axial fans exhaust air along the axis, with the intake and exhaust ports aligned on a single axis parallel line. Centrifugal fans, on the other hand, exhaust air perpendicular to the intake direction, allowing for 360-degree directional exhaust. 2. Installation difficulty: Axial fans are relatively easy to install, typically mounted directly on walls or connected to ducts.
