What Is a Blower?

A blower is a general term for equipment that blows air.

A blower and a fan are considered synonymous in the same standard. However, in industrial settings, the above distinction is rarely made clearly, and blower is often used as a generic term for these types of blowers, with fan being used for those with relatively weak discharge pressure blower for those with relatively strong discharge pressure.

Types of Blowers

Various types of blowers exist depending on the impeller, which is an important component or part for generating airflow installed inside the blower.

A fan is broadly classified according to the direction in which gas passes through the impeller. Centrifugal fans, in which the gas passes through the impeller in the radial direction, include turbofans (backward-facing blower), sirocco fans (multi-blowers), and radial fans.

Other types of fans include line fans (diagonal flow blowers), in which the gas passes through the impeller at an angle to the axial direction, and axial flow fans, in which the gas passes through the impeller in the axial direction.

Blow guns and blower vacuum guns are also used to pump gas locally.

1. Sirocco Fan

Sirocco fans, also called multi-blade fans, usually have about 30 to 60 short and wide blades. Although their efficiency is relatively low (about 60%), they are mainly used as blowers for ventilation in buildings and ships, and for boiler ventilation because of their compact design and low noise level.

2. Radial Fan

Radial fans are a type of centrifugal blower with 6 to 12 parallel blades, usually made of steel, which are resistant and easily replaceable, and are used in sites and industries that transport gases containing solids such as particulates (dust, pulverized coal, cement, saw dust).

3. Turbo Fan

Turbo fans have an impeller structure similar to that of volute-type water flow pumps, and are used in a wide range of applications due to their high efficiency.

It is also highly resistant to heat, corrosion, and abrasion, and is used to promote combustion in incineration facilities, induce exhaust gases, transport gases containing powders and fine particles, and provide air conditioning and dust collection in the manufacturing processes of food, medicine, textiles, and metals.

4. Plate Fan

Plate fans are small, low-noise blowers among many other types of blowers, and are highly tolerant of continuous operation.

They have a wide range of applications, and can be used in dust collectors, crushers, dryers, incinerators, and other sites where general airflow is required.

Blower Applications

Blowers alone are used for air conditioning control, such as intake and exhaust air in facilities, air and oxygen supply at manufacturing and production sites, and various treatment plants, as well as for dust cleaning work. They are also incorporated into the interior of various products, such as cooling systems for electrical appliances and aircraft engines.

As mentioned above, the type of impeller and the material used for each type of blower varies greatly depending on the site and the environment in which it is used. It is very important to select the appropriate type of blower.
