Consider these points before buying Air Blowers



Air blower is an electro- mechanical device for creating current of air, which is used to dry or heat something at a substantial pressure. Fans and blowers are necessary for air to overcome the flow resistance caused by components like ducts and dampers. A blower is another name for a fan that operates where the resistance to the flow is primarily on the downstream side of the fan. Some makers of portable fans refer to their units as blowers even if they don’t necessarily conform to ASME distinction, which applies to permanently installed industrial process equipments.

These fans increase the speed and volume of an air stream with the rotating impellers (a rotor used to increase the pressure and flow of a fluid).The working of it goes by a no. of rotating blades, which is connected to a shaft and driven by a motor or turbine. Blowers operate with a pressure ratio of 1.11 to 1.2, which makes them intermediate between a fan and a compressor.


Based on the pressure and airflow requirements of each application, either a fan or a blower is used. So, the two main categories of blowers are:

  • Centrifugal Blowers: It is contained within scroll-shaped fan housing. The air inside the spinning fan is thrown off the outside of the wheel. Inlet and outlet ducting are often attached to fan’s housing, to supply and exhaust air based on industry requirement. They include a gear system to achieve speed. Their main limitation is that airflow decreases rapidly when an obstacle raises pressure, making them unsuitable for applications.


  • Use: They are used for combustion air supplies, in industrial applications such as ventilation, cooling and heating system, dust control etc.


  • Positive –displacement Blowers: It has a rotor geometry designed to capture pockets of air, driving flow in the intended direction at high pressure. They are similar to positive displacement pumps. Among positive displacement blowers, the Roots, or the rotary lobe, type is common. It uses mechanical means to squeeze fluid and increase pressure or velocity. It’s done by trapping a certain volume of air then discharging or forcing it out against the system pressure.


  • Use: They can be used anywhere, gas needs to conveyed and compressed.

People nowadays are very careful and conscious about time because of their daily hectic schedules. The technology and digitalisation has already helped them a lot with their chores. Household chores are a manic activity. Air blower reduces usage of time and energy. Now, Air Blowers or Vacuum Cleaners that is also a kind of blower can use for cleansing of any delicate household or other items.

People think and then take decisions for every action in their life. Even if we have to purchase anything, we have some factors according to which we spend and buy.

Here are some important factors to pounder when you are buying an air blower, which you may need:

  • Quality: We always go for the branded company products because of the quality factor. It should be the first priority while buying any electronic device. So, one should always check the description of the product i,e. check the materials and other items used in the product. We also sometimes compromise with budget just for the better quality.


  • Blower Type: The most common type of blower being used is centrifugal. Positive –Displacement blowers are also in use by many manufacturing industries. Both are being used at various places according to specific work and requirement. In this, buyer should also check blades. They should be easy to clean, so that, it works smoothly and properly.

  • Eco-friendly: While buying an electronic appliance, this factor should always be in mind. Most of the electrical devices make noise which can annoy the people and environment around you. Go for battery operated blowers for small tasks. They get easily charged and also make less noise, especially if used for longer hours.
