In various commercial and industrial areas,
one air moving equipment that is widely demanded is the centrifugal fans. This kind of fan comes with a great list of
benefits such as energy efficiency, durability, and low maintenance. Whenever
you’re trying to improve ventilation in your spaces, it can be difficult for
you to know where to start.
In the market, there is the availability of a
number of fans that work efficiently by creating low pressure at the blade’s
center. To choose the right one is somewhat tedious and confusing, so here a
list on the basis of you can make your selection of the centrifugal fan. Let’s
have a look at each of the factors clearly:
On
the basis of functionality
There is different functioning of a
centrifugal fan depending on your requirement. Are you looking for the fan to
move about the material or clean the air? Once you are clear about the
functionality of the fans then you can easily find the right one for your
application. In the backward curved fans, there are powerful blades that are
used for cleaning the air. But these fans can give you wider options for
functions.
Blade
types
Another pointer on the basis of which you can
decide your kind of fan is the type of blade. Some of the different types of
blade types that you will get to see are airfoil, forward curve, backward curve,
and radial. Each of these blades has different functioning and performance. So,
before finalizing the fans of your choice just have a look at the functioning
of the fan blades in a detailed manner. If the blade is satisfying your
requirements and purpose then go with it.
In
terms of static pressure
Static pressure is mainly described as the
friction that is created by the air in the duct. The centrifugal fans are specially designed to withstand the air
volumes in static pressures. In the backward inclined fans, there will less
static pressure. But, a backward curved fan has the ability to handle the
double static pressure. So, don’t forget to consider this factor while choosing
a suitable fan for your establishment. Always make sure that you are contacting
reliable and known manufacturers of centrifugal fans. Do consider the previous tracks and reviews of the
manufacturers before finalizing them.
Velocity
needs
Last but not least, it is important that you are
looking at the velocity requirements in the industries. While choosing the fan,
find out how much pressure is needed to perform the airflow in the duct. With
this, you will be able to know which fan is suitable for your velocity needs.
