The centrifugal fan was originally designed and invented in the early 19th century by a Russian military engineer who was known as Alexander Sablukov
. A centrifugal fan is one of the most commonly used fans today as it is easier to make than an axial fan, but more importantly it is also far cheaper to make.
The centrifugal fan is used in our cars engine for example. They are used to cool the internal combustion engine, using energy that is created from the engine itself. They are also used in buildings to help with ventilation, heating and cooling systems. Another example of where a centrifugal fan would be found is in a commercial or professional kitchen where temperatures often reach and exceed 100C.
Centrifugal fans can be built with a single or double inlet, with either forward curved or backward curved impellers. They are made from metal with a standard or external rotor motor as its main operation. A backward curved centrifugal fan with a motorised impeller for example would be used for things like air filtration, air conditioning cassettes, roof extract units or lamp cooling. It would also be used to cool solarium equipment or refrigeration equipment as well. A forward curved centrifugal fan with a double inlet would be used in things like air conditioning units, air handling units or air curtains.
Laboratories, pharmaceutical companies and chemical stores will also use centrifugal fans as a way of keeping the air clean so important research work can be carried out in a clean and safe environment. They will use a fan that is corrosion resistant due to the sensitive environment in which they work in, with these fans being made from plastic or to use its proper name a polypropylene moulded construction fan.
