Axial Flow Fan Types

The flow is axial at entry and exit.

Axial flow fan types.

Fan types capacity static pressure air flow sizes. In a cross flow fan the air flows in an inward direction and then in an outward radial direction. It shall be vane axial fan with airfoil blades. The volume flow is plotted along the x axis and the system pressure is plotted on the y axis.

Axial flow fans have blades that force air to move parallel to the shaft about which the blades rotate. Mixed flow fans develops higher pressures than axial fans. Ul or cul is avaliable for usa and canada market. Search the engineering toolbox search is the most efficient way to navigate the engineering toolbox.

Can electric parameter be customized. Centrifugal fans also require a higher power input. The fan shall be direct driven and in a cylindrical structure. 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.

Behind the impeller in the cylindrical body there shall be guiding vanes for airflow straightening. They provide the fan type size number of poles of the motor shaft power and sound power. As a resistance to flow is applied to the suction or exhaust side of the fan the volume flow rate will drop. 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. The airflow created by centrifugal fans is directed through a system of ducts or tubes. In a mixed flow fan the air flows in both axial and radial direction relative to the shaft. The fan selection graphs allow us to make a quick selection of the axial flow fans normally used at 50 hz.

Exhaust fan cooling pads fire fans axial fans negative pressure fan hot water air heater environmental temperature and humidity air conditioning etc. 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. Yes dwe can supply the product with ul to you. The quick selection charts nomogrammed sheets and our dimension sheets give an overview over the most commonly used axial flow fans.

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. 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. When there is no pressure in the system the fan is blowing freely an axial fan will produce the greatest volume flow.
