Axial flow fan types.

In a cross flow fan the air flows in an inward direction and then in an outward radial direction. Axial flow fans have blades that force air to move parallel to the shaft about which the blades rotate. 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. An axial fan is a type of fan that causes gas to flow through it in an axial direction parallel to the shaft about which the blades rotate.

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. The volume flow is plotted along the x axis and the system pressure is plotted on the y axis. This helps create a higher pressure airflow than axial fans. The fan selection graphs allow us to make a quick selection of the axial flow fans normally used at 50 hz.

The fan shall be direct driven and in a cylindrical structure. The airflow created by centrifugal fans is directed through a system of ducts or tubes. The quick selection charts nomogrammed sheets and our dimension sheets give an overview over the most commonly used axial flow fans. Search the engineering toolbox search is the most efficient way to navigate the engineering toolbox.

Axial flow fans are applied in air conditioning and industrial process applications. Fan types capacity static pressure air flow sizes. They provide the fan type size number of poles of the motor shaft power and sound power. When there is no pressure in the system the fan is blowing freely an axial fan will produce the greatest volume flow.

Mixed flow fans develops higher pressures than axial fans. Yes dwe can supply the product with ul to you. Exhaust fan cooling pads fire fans axial fans negative pressure fan hot water air heater environmental temperature and humidity air conditioning etc. Centrifugal fans also require a higher power input.

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. As a resistance to flow is applied to the suction or exhaust side of the fan the volume flow rate will drop. In a mixed flow fan the air flows in both axial and radial direction relative to the shaft. 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.

Despite a lower flow rate centrifugal fans create a steadier flow of air than axial fans. Ul or cul is avaliable for usa and canada market. Types of fans axial and propeller fans centrifugal radial fans mixed flow fans and cross flow fans.
