Axial Fans, Propeller Fans, Inline Fans etc.
An axial fan moves air parallel to its axis, similar to a propeller, and is used for high-volume, low-pressure applications like ventilation and cooling. The rotating blades create a pressure difference that draws air in from one end and expels it out the other in a straight line, making them common in HVAC systems, electronics cooling, and industrial exhaust systems.
A propeller fan is a type of axial fan that moves a large volume of air at low pressure and consists of a propeller-like blade mounted on a rotating shaft within a ring or cage. These fans are commonly used for ventilation and cooling in applications with low resistance, such as exhaust fans in walls, ceiling fans, and room fans.
An inline fan is a ventilation fan mounted inside a duct system, typically in a hidden location like a ceiling void or attic, to move air from one area to another. It pulls air through ducting to exhaust it to the outside or move it to another location, making it quieter and allowing for powerful performance over long duct runs.
