Though summer is coming to an end, temperatures are
still soaring. A fan or cooler is invaluable to any room or workplace. It is
required in all seasons and keeps the room well-ventilated. As against ceiling
fans, going in for a portable cooling fan is much more beneficial.
Portable cooling fans are small,
handy, powerful, and convenient and can be moved from one room to the other
with ease.
Most often, people find it difficult to buy small portable fans online. Therefore, in this article, we will discuss the important things
you must consider when choosing a portable
cooling fan.
Efficiency: There are several factors that affect the
efficiency of a fan. Some of them are:
v Case design: Fans housed inside casings are more efficient than
those enclosed in open wire guards. With casings, the airflow can be 50%
higher.
v Fan design: Axial fans are 70% more efficient compared to
paddle fans.
v Speed control: In most low cost fans, a lot of energy
is wasted. This can reduce the life of the motor. High efficiency portable cooling fans use electronic
speed controls that waste very little energy.
Efficient small
portable fans are expensive initially but in the long-run save a lot on
energy and electricity bills.
Fan and air noise: Design of the fan blades reduces the noise levels
considerably. Noise is an important factor to consider when choosing a fan. It
is an important consideration when choosing a fan for an office, shop, hospital
or workplace.
Impellor size and airflow
Many people buy the biggest fan available assuming
it will give the highest airflow. But remember, a large inefficient fan will
use more energy, but will not necessarily produce the highest airflow.
Speed control
A portable fan with step less electronic control is
flexible because the output can be set exactly at the level required for any
situation and bigger fans can be installed which will give the option of higher
output if needed. As a general rule, always choose the fan with the biggest
airflow.
Quality
The last, but the most important consideration when
choosing portable fans is to examine their quality. Quality includes things
like the materials used in construction, thickness etc. For example, a fan
designed for light domestic use is not as durable as one built for commercial
use or heavy industrial use.
Thus, keep these points in mind when choosing portable cooling fans.
