Axial Fan

Axial Flow Fan – Modern Industrial Equipment Required For Cooling And Air Supply Needs An Axial flow fan takes in air parallel to the axis of blades that rotates around it and forces the air out in the same direction. They can create airflow at a high rate and are capable of generating air flow in large volumes. The key reason why they are needed in industrial units is for the purpose of supplying fresh air. They can also be used to suck the air coming from return air trenches and rotary filters. They can also be used for the purpose of exhausting air out. The most common applications in which it is used are air-cooled condensers, cooling towers, air cooled heat exchangers etc.

Axial Flow Fan is pivotal part of any industrial or a factory setup. As the name suggests, it is an industrial fan which serves the purpose of cooling down the machines and equipment in a factory.

Axial Flow Fan is adept in generating an airflow that is parallel to an axis and that is how it gets its name. A propeller within the axial flow fan is responsible for generating the pressure that influences a suction force, which results in retaining a flow across the fan.

Axial Flow Fans can be designed in various ways depending upon the requirement. Furthermore, they can also be customized.

​ ​ What Are The Main Qualities Of An Axial Flow Fan?
The key feature of Axial flow fan is that it makes air flow through it in an axial direction. The air that flows through is axial both at the entry and also at the exit. The main difference between an axial fan and a centrifugal fan is the way in which both devices move air. The axial flow fan makes use of a propeller to get air into it and send the air out in axial direction. However the centrifugal fan gets air into the blower housing using one seven types of wheels and discharges this at a ninety degree angle.

What are the components of Axial Flow Fans?
1. Motor.
2. Blades.
3. Impellers.
4. Casing

What are the Key Features of Axial Flow Fans?
• The design of the axial flow fan is such that it is capable of providing higher energy-efficiency.
• More conveniently, it has lower noise as compared to other conventional fans.
• Ability to generate propagate better air movement using relatively lesser energy.
• Provide High-cost savings up to 40%.
• Available in wide variations.

Applications of Axial Flow Fans:
• Cooling down areas within a factory, where significant heat is produced.
• Ventilation in factories, warehouses, Forging, engines, etc.
• Paint Spray Booths.
• Spot Cooling of industrial machinery like generators & transformers.
• Welding booths.
• Mills & Petro-chemical industries.
