Impeller Fan

From small electronics to large mechanical constructs, impeller fans play a significant role in keeping these devices cool and in working condition.

 

Often going by terms such as centrifugal fan , blower fan , squirrel-cage fan, or biscuit blower, impeller fans are one of the most commonly used apparatuses given their simplicity and cost efficiency in production. Along with these traits, their functionality has made them suitable for air-pollution control, as well as industrial facilities.

 

Much like any piece of machinery that is utilised for complex functions, different types of impeller fans are available for the task at hand. Given the specific tasks one might require an impeller fan, it is important to familiarise yourself with the different types and their functions.Types of Impeller Fans

 

Closed Impeller

Held between two sturdy plates of equal or greater size, the closed impeller is the one most often used. Its greater efficiency in channelling the propelling force from the eye to discharge port makes it a popular choice.

 

However, it is often limited to handling clear liquids.

 

Semi-Open Impeller

Missing a plate on one side, the semi-open impeller is often considered less efficient but more flexible than the closed impeller.

 

However, it’s open-faced feature allows it to handle more viscous liquids than the closed impeller, and it can even weather foreign particles in the propelling liquid.

 

Open Impeller

Optimal for handling suspended liquids and fluids denser than the types functional for the closed and semi-open impellers, open impellers have their own cons as well.

 

Lacking a plate on either side of their structure, these impellers tend to be weaker than others due to the lack of support. To compensate for the structural weakness, open impellers are often smaller and less taxed to prevent damage.

 

But First, Navigate Utility with WSK

Ultimately, each impeller fan serves a different purpose. It is important to understand the utility of the device before selecting the specific tool as the efficiency of the product will vary depending on the conditions.

 

At WSK, a careful and meticulous selection process guides the selection of the device. From fans with 100mm to four metres in diameter, WSK’s aerofoil blades vary in their specifications and are designed to serve your specific needs.
