What Is an Inline Fan?
An inline fan is a type of blower that incorporates a fan and an electric motor inside a casing to which sound-absorbing material is affixed.
They are used in various buildings, such as offices, hotels, movie theaters, and factories as air conditioning and ventilation equipment. Most of them are installed in such a way as to be suspended from the ceiling, etc., and are connected to ducts that serve as ventilation channels to transport air inside or outside a room.
Other types of inline fans include centrifugal and axial fans. Fans are characterized by higher pressure for centrifugal fans and higher airflow for axial fans.
Uses of Inline Fans
Inline fans are a type of blower used for air conditioning, air supply, and air exhaust in most buildings, including high-rise buildings, hospitals, hotels, schools, theaters, and factories.
Most of them are often installed in a suspended position, in line with ducts installed in the ceiling or elsewhere.
Most inline fans have a built-in diagonal flow fan as the fan. This diagonal flow fan is used when both air volume and pressure are required, and is therefore suitable for such situations as well as for use.
Principle of an Inline Fan
An inline fan consists of a diagonal flow fan, an electric motor, and a round or box container with sound-absorbing material attached to the inside. The fan may also incorporate a centrifugal fan.
Most fans are driven by a direct drive system that directly connects the fan to the electric motor, but belt drive systems are also used.
Recent boxes have a structure in which sound-absorbing material is placed to fill the gap between the fan and the box, and the fan is held in place by the sound-absorbing material.
A fan is a rotating machine that gives energy to air or other gases through its rotation. A centrifugal fan bends inhaled gas at a right angle and discharges it, while an axial flow fan used for fans sends the gas backward. Therefore, centrifugal fans have the effect of increasing speed and pressure due to centrifugal force, while axial fans have almost no such effect.
