Axial Flow Fan Types

This helps create a higher pressure airflow than axial fans.

Axial flow fan types.

Axial flow fans have blades that force air to move parallel to the shaft about which the blades rotate. In a mixed flow fan the air flows in both axial and radial direction relative to the shaft. The operating environment of a typical engine cooling fan has favored axial flow fans and at the same time posed obstacles to successful adoption of alternative fan types. The quick selection charts nomogrammed sheets and our dimension sheets give an overview over the most commonly used axial flow fans.

This type of fan is used in a wide variety of applications ranging from small cooling fans for electronics to the giant fans used in wind tunnels. Ul or cul is avaliable for usa and canada market. The flow is axial at entry and exit. All applications of fans in ventilating cooling heating and air conditioning processes have their unique set of environmental factors that dictate the fan design but.

Despite a lower flow rate centrifugal fans create a steadier flow of air than axial fans. Axial flow fans are applied in air conditioning and industrial process applications. Can electric parameter be customized. It shall be vane axial fan with airfoil blades.

Types of fans axial and propeller fans centrifugal radial fans mixed flow fans and cross flow fans. In a cross flow fan the air flows in an inward direction and then in an outward radial direction. The fan selection graphs allow us to make a quick selection of the axial flow fans normally used at 50 hz. They provide the fan type size number of poles of the motor shaft power and sound power.

Behind the impeller in the cylindrical body there shall be guiding vanes for airflow straightening. As a resistance to flow is applied to the suction or exhaust side of the fan the volume flow rate will drop. Centrifugal fans also require a higher power input. Exhaust fan cooling pads fire fans axial fans negative pressure fan hot water air heater environmental temperature and humidity air conditioning etc.

Search the engineering toolbox search is the most efficient way to navigate the engineering toolbox. The airflow created by centrifugal fans is directed through a system of ducts or tubes. The fan is designed to produce a pressure difference and hence force to cause a flow through the fan factors which determine the performance of the fan include the number and shape of the blades. When there is no pressure in the system the fan is blowing freely an axial fan will produce the greatest volume flow.

Fan types capacity static pressure air flow sizes. The volume flow is plotted along the x axis and the system pressure is plotted on the y axis. Mixed flow fans develops higher pressures than axial fans.
