Kinds Of Electric Followers

 

Most electric fan suppliers will offer two kinds of fans depending upon the design, the axial fan as well as the radial follower. Both have advantages as well as negative aspects and also are more or less ideal for certain locations of application.

The Axial Follower:

Axial fans are utilized anywhere high volume circulations (air quantities) are called for in connection with low pressures (resistances that need to be overcome).

The framework of the axial follower is similar to that of an airplane propeller. It sucks in the air axially (through the motor axis) and blows it out axially.

 

The residential properties of the axial follower:

 

  • Small space requirement because of compact design and straight airflow. Ideal for usage with straight consumption and also straight exhaust, e.g. with wall or home window fans.
  • Easy structure, hence cost-efficient growth and production.
  • Due to the high particular curve of the axial fan, the system stress must be calculated specifically when components of an airflow system are attached.

The Radial Fan:

Radial followers are identified by greater stress. They are for that reason best suited for use in ventilation systems with upstream or downstream filters, air heating systems, and so on.

 

Centrifugal fans approach a drum. They absorb the air by means of the motor axis and also blow it out once again at an angle of 90 °.

The buildings of the centrifugal follower:

 

  • Greater space requirement due to air deflection by 90 °.
  • Typically better efficiency than axial followers.
  • Lower outer speeds result in less sound than with axial fans.
  • Greater available compressions (pressures). This makes it optimal for usage in ventilation systems with upstream or downstream units such as air filter boxes, heat exchangers, etc.
  • Due to the flatter characteristic contour contrasted to axial followers, a radial follower is much more tolerant of boosts in pressure loss, e.g. due to filters progressively ending up being unclean.
